We're a profitable B2B services company ($3M–$50M ARR clients) actively building a proprietary AI platform — and we need the technical leader to own the execution.
WHAT WE'RE BUILDING: A multi-agent AI platform that operationalizes our founder-story methodology into deployable client systems. Architecture spec exists, pieces are already in production. We're not starting from scratch — we're scaling a real build.
THE STACK: LLMs (Claude, GPT, Gemini), multi-agent orchestration (LangGraph/LangChain), RAG pipelines, vector databases, React/Next.js, Python/Node.js, AWS, n8n/Make for automation.
WHAT MATTERS MOST: You're not just an executor. You come to the leadership table with tools and approaches we haven't seen yet. You translate the CEO's vision into a technical spec, a build plan, and a shipped product — without needing everything pre-defined.
THE TEAM: 4 core people. You'd join the CEO, a Growth Strategist, and an Operations Manager — and lead one AI Engineer (your first direct report).
ENGAGEMENT: Starts fractional with a clear path to full-time and equity for the right fit. We're not VC-funded by design, so equity is unencumbered.

Chestnut builds the systems insurance carriers actually run their distribution business on. We replace spreadsheets, legacy vendor systems, and manual processes with real-time data, deterministic workflows, and AI-assisted tooling.
This is end-to-end product engineering.
You won’t just write APIs. You’ll design schemas, build backend logic, ship UI, deploy to production, and handle the sharp edges that show up with real customers. The problems are messy and state-heavy: payouts that must reconcile with finance, onboarding flows with regulatory constraints, dynamic hierarchies, retries, chargebacks, partial failures.
We care a lot about correctness. These systems move real money and cannot drift.
Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS
We use AI heavily in our workflow — for drafting, refactoring, test generation, and exploring solutions. We expect engineers to use it aggressively. We also expect you to understand what it’s doing, spot when it’s wrong, and maintain strong fundamentals. Taste matters.
You’ll likely thrive here if you: - Have 3–6 years building real product systems - Are strong in at least one typed language and comfortable picking up others - Enjoy owning features end-to-end - Think in terms of invariants, edge cases, and failure modes - Like shipping quickly but cleanly - Want to build systems that operate in production, not demos
We’re a small, high-agency team. You’ll have meaningful ownership and direct impact on customers.
Hybrid in SF and Seattle.

At Formical, we believe we can become the first sustainable generation on Earth. Biotechnology plays a key role in this future - benefiting all people, animals, and our planet by making industrial production more sustainable. But bioprocessing still runs on fragmented data and tacit knowledge. The infrastructure to turn data into the intelligence that teams need to scale doesn't exist yet, hindering the sector’s progress. Our product accelerates bioprocessing by connecting fragmented data, enabling predictive modeling, and ultimately closing the loop between measurement and action.
We're not looking for specific skills, just willingness to learn. I joined a couple months ago with little React/TypeScript full-stack experience, but with CC I managed quite well coming from a Python backend background. Nothing's enforced though! We're a small team, have some customers, and are looking to build out the platform and the client-base significantly this year.

We're looking for people who have great startup energy, want to win, and bring great vibes to our tight-knit team.
I'm Kris, a manager on Access Control at Verkada.
Access Control is a core product at Verkada. We build the systems that power how customers secure and manage their offices, schools, and campuses. Our software unlocks nearly 8 million doors every day. These are mission-critical systems, not internal tools, and reliability and usability matter a lot.
My frontend team builds more than small widgets or forms. We design and deliver entire workflows that bring clarity to complex systems - managing doors, groups, schedules, users - all within a unified, elegant interface. This means working closely with world-class designers (and debating them when needed), but also having the vision and technical depth to lead when design resources are scarce.
I'm looking for a React expert who can bridge craft and leadership: - Lead technically within the frontend team, setting patterns and guiding others. - Collaborate deeply with our web infrastructure and component library teams to shape the building blocks of our platform. - Champion UX - because building secure, intuitive experiences at global scale is as much about design empathy as it is about React/Redux mastery.
This is a team for engineers who want real ownership, visible impact, and problems rooted in production reality. Verkada is pre-IPO with a $5.8B valuation, and the entire engineering org is about 350 people, which keeps scope high and teams relatively autonomous.

Bubblehouse is a fast-growing custom loyalty platform, tripling the revenue each year. Headquartered in NYC, the entire team is fully remote and spread across the globe. We power loyalty programs for brands like American Girl and Old Spice.
We’re expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.
We run on Golang and use custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.
Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.
Looking for:
1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.
2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)
3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)
4. Broad experience across multiple programming paradigms, platforms and software stacks.
5. Demonstrated care for the software craftsmanship (which can take many forms).
6. Great spoken English, and ability to communicate 9am to noon in New York time zone.
We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.
Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.

Despite rapid growth, we retain the stability of a self-funded, profitable company. Role Overview: As a Senior Software Engineer at Ping, you will work onsite in Delhi, India, sitting alongside our data entry team to increase efficiency, streamline processes through ML and UI improvements, and triage and fix bugs that occur overnight (US time). You will have a direct, daily impact on production quality and team productivity. Occasional work from home is available. Responsibilities:
Work closely with the data entry team to identify bottlenecks, streamline workflows, and build tooling that increases throughput and accuracy. Develop and implement ML-driven and UI-based improvements to internal processes. Triage and resolve production bugs that arise overnight, ensuring smooth operations for US-based customers each morning.

Oversee projects from problem identification through deployment, including architecting solutions, running experiments, and managing rollouts.
Required:
Minimum 5 years of experience in software development. Strong proficiency in React, TypeScript, and modern frontend practices. Comfort working across the stack — willingness to dig into backend (Python/Django) and ML pipelines as needed. Proven track record of deploying and maintaining production web applications. Strong debugging and problem-solving skills, especially under time pressure.
Preferable:
Experience with machine learning workflows or data processing pipelines. Familiarity with Python/Django backend development. Knowledge of cloud services (AWS) and containerization (Docker). Experience in insurance, fintech, or data-intensive industries.
Tech Stack: React, TypeScript, Python, Django, SCSS, Redux Toolkit, Jest, Webpack, Node.js, Git, AWS. Why Join Ping: Be a key player with direct influence on how our team operates day to day. Work with a top-tier team of insurance and tech veterans building ML-powered products that are transforming the property insurance industry. Your work will have immediate, visible impact on production quality and team efficiency. Please apply at jobs@pingintel.com
We're looking for a backend-leaning fullstack dev. You will be one of the first engineers outside of the founding team. Here is a bit more about us: We're a seed stage AI startup backed by top tier investors. We're on a mission to ensure every patient gets covered for the care they need and every doctor gets paid for the work they do.
We’re building deep, vertically integrated technology systems to solve fundamental problems in US healthcare - the biggest market in the world ($5T). We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!
We are a founding team made up of ex-YC, Amazon, Meta, Microsoft, and Harvard Business School with previous successful exits.
You’ll own entire product areas and be expected to play a true full-stack role, with the ability to go from customer need to end-state product. You’ll work directly with the CTO at the edge of what's possible with LLMs and agentic systems applied to a hard domain. You'll contribute to technical strategy, make real architectural decisions, and write vast amounts of production code with AI first developer workflows. Most importantly, the technology you build will have real impact on real people - clinics staying open, clinicians getting paid, patients getting care.
This is an opportunity to work in a fast paced, high ownership environment while solving real problems in healthcare.
We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!
Luminate is the entertainment industry’s preeminent data and insights partner, serving as the single source of truth for record labels, film studios, talent agencies, and every part of the music and entertainment ecosystem.
The team's stack is Java w/ Spring, React w/ Typescript, and SQL w/postgres, and snowflake. We use playwright for e2e testing and deploy our infra on AWS.
The team is relatively new (around 3 years old) but is working on an older codebase with plenty of tech debt. Luckily we actually _do_ get time to address our tech debt and take the time to leave our code better than we found it, so it's getting better all the time.
We have an oncall rotation but getting paged is pretty rare.

Please mention Hacker News in your cover letter.
Mixpeek is multimodal AI infrastructure — we turn unstructured content (video, images, audio, documents) into searchable, programmable assets through a unified API. Think of us as the data infrastructure layer that sits between your raw media and your AI applications. If you've ever tried to build a pipeline that extracts features from video, makes them retrievable, and serves them at scale — you know this is a 12-18 month infrastructure project. We compress that to an afternoon.
We're currently building MVS (Mixpeek Vector Store) — a distributed vector database built on Ray + S3, designed to handle 100B+ vectors at a fraction of the cost of existing solutions. Architecture details: shard-level WAL, LIRE-based adaptive search, replica sets, and agent-native query primitives. If you've ever wanted to rethink how vector search works from the storage layer up, this is that project.
Some things we're shipping right now:
- IP safety for media & sports — our copyright detection platform (https://copyright.mixpeek.com) helps brands and leagues detect unauthorized use of visual IP at scale. We're working with partners in the media/sports ecosystem including Backblaze for storage-native integration.
- Healthcare pipelines — multimodal extraction for clinical trial recruitment and SNF/MDS coding workflows, working with enterprise partners in the space.
- Ad verification — we contribute to the IAB Tech Lab ARTF working group and power contextual intelligence for ad safety.
Our core primitives: feature extractors, retrievers, taxonomies, clusters. Decompose with extractors, recompose with retrievers. Docs: https://docs.mixpeek.com
Stack: Python, Ray, S3, FastAPI, React/TypeScript. We also maintain amux [https://github.com/mixpeek/amux], an open-source tmux multiplexer for running parallel Claude Code agent sessions — if you're into agentic dev workflows, check it out.
I'm Ethan (founder/CEO, previously led search at MongoDB). Small team, high ownership, real problems. We're preparing for NAB Show next week and scaling enterprise pipeline work across healthcare, adtech, and media.
Reach out: ethan [at] mixpeek [dot] com — mention HN.
Senior Software Engineer: You'll own complex technical problems end-to-end—translating customer needs into scalable architecture, optimizing AI model efficiency through prompt engineering, and shipping features that directly impact how revenue teams operate. We want bold ideas and people who push boundaries.
Junior Software Engineer: You'll work across our stack (Python, FastAPI, Next.js, React) alongside senior engineers, contributing to real features from day one. Great fit if you're hungry to learn, ship fast, and grow with a startup building cutting-edge agentic systems.
New Grad Software Engineer: Entry point for recent grads excited about AI and agentic systems. You'll get hands-on experience with our modern data stack (Postgres, ElasticSearch, ClickHouse, DuckDB), Kubernetes/AWS deployment, and Temporal.io workflow orchestration while shipping production code.
This role is based in our Manhattan office (4 days/week in-person). Full health and dental coverage.

We're building an AI platform for credit unions. A variety of tools (third party integrations + RAG) backed by multiple LLM options, including OLMo, running in our own AWS infrastructure. We're a small team (I'm CTO and our first technical hire) so you'd have real ownership over the AI stack and architecture.
You'd work on retrieval over heterogeneous corpora with citations, agent orchestration and tool calling, model serving infra, and third party API integration. There's a lot of room to experiment with hierarchical retrieval, heavier upfront document processing, and custom agent tooling. Over time we're going to expand into fine tuning, more direct compute management, and some interpretability work.
Stack: Python/FastAPI, React, PostgreSQL/pgvector, AWS/OpenTofu. Looking for someone with a few years of experience building production systems.
Email me at talati@getcultivate.ai if you're interested!

Join builds collaboration software for the construction industry — helping contractors, owners, and architects coordinate on high-value projects. React, Golang, Postgres. We deploy to AWS via Terraform.
We're hiring multiple senior/staff engineers across a range of profiles: frontend-heavy, fullstack, and backend-heavy. We're especially looking for 1–2 engineers with architect-level frontend chops (React, TypeScript, state management, perf) who can own UI quality and level up the team. But we're also very interested in strong Go/Postgres or infra/ops backgrounds.
Day to day you'll write code (25–75%), review PRs (25–50%), and pair/mentor/document (10–20%). You'll act as a technical lead on projects, break down large efforts, and influence architectural decisions across the org. Small cross-functional teams with a designer, PM, and EM.
Stack: React, TypeScript, Golang, Postgres, GraphQL/Apollo, Vite, Cypress, Terraform, AWS (ECS, RDS, Lambda). We lightly use Elastic and are interested in event-driven patterns.
Fully remote, 100% employer-paid medical, 401(k), two company-wide shutdown weeks, continuing education budget.
To apply: send resume to jon@join.build. If you are able to please include a PR review you've given that had a positive impact (or a description/snippet if that's confidential).
We're a Dental Support Organization running 59 practices across TX/OK/CO/MO/IA/NE/TN/AZ. The unsexy industry description hides what's actually an interesting technical role: a small dev team with real ownership, pushing hard on automation and AI to make dental operations actually work well.
Stack is primarily Rails 7.1 (Hotwire+Stimulus.js), with some React/Electron, C# .NET (OpenDental), and tiny bit of Go — all on AWS.
You'd be joining a tight team where developers own problems end-to-end: from understanding why a billing workflow breaks down, to designing the fix, to shipping it. The domain is surprisingly broad — patient communication, PMS integration, payroll, clinical workflows — and there's no shortage of genuinely novel problems once you learn the business.
Good fit if you like: stable company, small team, broad latitude, and work that visibly matters to the people using it. Not a fit if you need a large eng org — but there's plenty of greenfield work as we're still actively building new features, not just maintaining legacy code.

We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write open-source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

Alterdd is building the fit intelligence layer for fashion. Currently, brands lack structured data on how their products actually fit real customers, making it a massively costly problem. We are fixing this by helping brands understand their fit so they can sell clothes that fit correctly the first time.
We are looking for our first technical hire to take full ownership of our engineering, moving our technology from prototype to production.
Why this role is interesting:
This is specifically designed as a bridge for a hungry Senior Engineer who is ready to step up into a Lead role. If you want the autonomy to build both the product and underlying systems from the ground up without waiting for direction, this is your shot to earn that Lead title. You will work directly with the founder with zero layers between idea and execution.
What you will do & stack:
- Design and build scalable systems across frontend, backend, and data layers. - Stack: Full-stack applications using TypeScript, React, Node, Python (or similar). - Data: PostgreSQL , building pipelines to ingest product feeds and fit data. - Integrations: Embedding our tech into e-commerce platforms like Shopify. You will need to design systems that handle highly inconsistent product and sizing data across different brands.
Working style & Interview: Hybrid working (2-3 days a week in person) in London or Cambridge. The interview process is fast and respects your time: one online technical interview, followed by one in-person interview with the founder.

At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.
We just announced our $42M Series B last week! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.

We're building an AI-native clinical data platform from the ground up, not a legacy system with AI bolted on. AI is core to the architecture, the development workflow, and the product itself. Fully funded by a private family office, no outside capital needed, no fundraising runway concerns. We're assembling the founding team now.
We're building a founding team to revolutionize healthcare in the United States, and we're hiring a technical operations lead. Best analogy: studio engineer to a recording artist. You own the environment so engineering leadership stays on high-leverage product work. That means CI/CD, QA, testing infrastructure, compliance documentation, and 30-40% independent feature development. Ground-floor equity in a company that's pre-revenue by choice, not by circumstance.
Hard requirement: you are already shipping software with AI coding tools daily (Claude Code, Cursor, Copilot, or similar). Not curious about AI. Not experimenting. Actively building and deploying with it. If you can't show us something you built with AI tools in the last 60 days, this isn't the right fit. Stack: React/Next.js, Python, PostgreSQL, Docker, AWS. But we care more about polyglot instincts than any single framework.
What we're looking for:
3-7 years full-stack experience Strong QA discipline (you write tests because you want to, not because someone made you) DevOps comfort: Docker, CI/CD pipelines, cloud infrastructure Self-directed. We don't micromanage and don't plan to start. Must be US-based or already have US work authorization. We do not sponsor visas.
What you get:
Meaningful early-stage equity (not a token option grant)
Direct access to founders and decision-makers, no layers
A say in the technical architecture from day one
Relocation to Miami fully covered
Health, dental, vision
Interview process: 15-min screen (show us your AI-built work) > take-home exercise > 2-hour paid working session > culture fit conversation.
Email: ksantos --at--direzzefamilyoffice.com, subject line "HN April 2026" so I can find you.
