We're a freight brokerage in NJ building a self-hosted, AI-first platform to replace our legacy CRM/TMS.
The AI compute infrastructure and data foundation are already in place. We need the architect who turns it into a production operating system.
This is a systems architecture role, not a feature dev role. If your primary strength is writing features or following tickets, this is not the role.
You will be responsible for: designing and deploying a PostgreSQL schema for complex freight operations across 30+ entities. Building Python service layers integrating multiple REST APIs. Wiring locally-hosted LLM inference into business workflows. Structuring systems that involve document ingestion, email processing, and asynchronous event-driven pipelines. Defining backend patterns for reliability and maintainability across a multi-million record environment.
The entire stack is self-hosted on custom-built server hardware. Database, application layer, AI inference — all of it. No cloud dependencies. No API rate limits. No monthly GPU bills. No vendor lock-in. You have direct access to the metal, you deploy on your terms, and the only ceiling on what you can run is the hardware itself.
If you've ever wanted to build a production platform without a cloud provider standing between you and your infrastructure, this is that role.
You are the first technical hire. You report directly to the owner, who is directly involved in this hire and in daily collaboration on the build. Architectural decisions are yours to make. AI coding tools and low-code UI frameworks are part of the workflow — your time goes to data models, service orchestration, and API plumbing, not hand-building screens.
Stack: Python, PostgreSQL, FastAPI, Docker, Neo4j, Linux, vLLM. Preferred: freight/TMS domain, Microsoft Graph API, CRM migration experience.
1-week paid onsite onboarding in NJ, then fully remote. Equity conversation open once mutual fit is established.
To apply, send: (1) your resume, (2) a brief writeup of a system you designed end-to-end — not code, but the architecture decisions you made and why, (3) a short note on why this role interests you.

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.

1. Solution Architect: You will partner closely with sales and customers to translate business needs into technical solutions, run technical discovery, and guide repeatable deployments and proofs of value for customers. This role is a great fit for entrepreneurial, customer-facing technical professionals who want a front-row view into how modern companies adopt AI at scale, and who enjoy working across technical discovery, solution design, demos, deployment scoping, and hands-on customer implementations, in close partnerships with Sales and Engineering
2. AI Solutions Engineer/Forward Deployed Engineer: You will partner directly with customers to architect, build, and deploy high-scale production AI applications on Baseten’s platform. You’ll own the journey with customers from initial exploration to production deployment. To be clear, this is a technical engineering role with hands-on coding and software dev that also includes aspects of product management, technical customer success and pre-sales solutions engineering mixed in. We’re language agnostic but strong Python and ML experience is a big plus.
3. Customer Engineer: You'll partner closely with Solutions Architecture, SRE, Infra, Product, and Forward Deployed Engineering, but you own the customer outcome end-to-end: from first response to root-cause analysis to the follow-up that reinforces trust. This role blends deep infrastructure debugging, AI/ML performance expertise, incident command, and proactive account ownership. You'll triage and resolve issues across Kubernetes, GPUs, networking, and model serving, lead war rooms during P0 escalations, and translate recurring pain points into product improvements.
The Offer:
Compensation: Very competitive, we’re looking for folks with a breadth of experience
Equity: This is an opportunity to participate in the ownership of a fast-growing AI Infrastructure platform
Location: We are based out of San Francisco with offices in New York. We are also open to remote employees for these roles.

BoWatt builds AI software for manufacturing complex hardware products like machines, medical devices or electronics. We’re a profitable, bootstrapped startup headquartered in Munich, with team members across Germany and the UK.
We’re looking for a full-stack engineer to own and ship features across our Go backend and React/TypeScript frontend, with the option to work on our AI features as well. You have to live in Germany and have the right to work here for this role.
We’re a team of eight, and more than half of us are former startup founders (deep tech, AI, psychedelics and gaming). We build closely with our customers and aim to strike the right balance between moving fast and not breaking things.

Common Prefix is a science-first blockchain consulting company. Our vision is to make blockchains usable for mainstream users and everyday people – paying at the supermarket, remittances, moving money across borders, saving, investing – and solving the real problems of usability, scalability, and interoperability that come with it.
We're a 30-person team, half scientists (cryptographer PhDs, post-docs, and professors) from renowned universities, half engineers with long web2 experience. A lot of our field is broken and we're trying to make a small contribution in fixing it, by introducing provable security and proper engineering practices across the board.
What we're looking for: Software engineers who can solve problems, are smart, get things done, and enjoy working on the bleeding edge, learning about cryptography, and working from first-principles. Auditors who can write and read code, especially low-level cryptographic implementation code (zero knowledge verifiers, signature schemes, etc), consensus (PoW, PoS), or smart contracts (everything DeFi). Support engineers (junior to early-mid) who enjoy being on the front line of production support (monitor live systems, respond to partner/user issues, triage/debug, and escalate). Formal Verification Engineers with hands-on experience in formal methods to work on machine-checked proofs of blockchain protocols and smart contracts.
Tech stack: Doesn't matter, we'll teach you. But we work mostly with Rust.
Open roles:
* Software Engineer, https://commonprefix.notion.site/sw-folk
* Auditor, https://commonprefix.notion.site/auditing-folk
* Support Engineer, https://commonprefix.notion.site/support-folk
* Formal Verification Engineer, https://commonprefix.notion.site/fve-folk
We offer:
* $80,000–$171,000 / year cash
* Local from Athens, Greece, or remote
* Conference participation in exciting scientific and engineering venues, 2-3 times per year
* The opportunity to work and learn from world-class scientists from major universities in the field of blockchains, cryptography, and consensus
We build geospatial AI infrastructure. Our platform lets analysts train custom object and change detection models on satellite/aerial/drone imagery in minutes, then reconstructs 3D terrain from those detections. We just shipped a planetary-scale simulation platform with Lockheed Martin powered by Unreal Engine.
If you want to work on distributed systems that run in a data center one day and an edge laptop the next, we have interesting problems. Our training and inference infrastructure is processing trillions of pixels and we deliver real world impact for our customers across defense, intelligence, and local governments.
Tech Stack: Python, Fast API, PyTorch, Postgres, Redis, Vue.js

Hi everyone! We're a Series A startup on a mission to protect society from fraud and money laundering using our intelligent Client Due Diligence Platform. With fraud and money laundering skyrocketing, regulated professionals are struggling to keep pace with their compliance obligations. Thirdfort turns compliance into a competitive advantage, offering beautifully secure onboarding for regulated businesses operating across legal and property.
We've already protected over 3 million people through life's big transactions, with a core aim to protect many more. We've spent the last year rebuilding our product from the ground up and are increasingly leaning into AI across the team/system, focusing on technologies that let product-minded engineers solve hard client problems fast and with confidence: Go, Temporal, NextJS and React Native. We expect our engineers to use their hard-won expertise to get deeply involved in product design as much as technical implementation — joining the team is a great opportunity to work with exciting tech and have a real impact on people's lives.
We have the following open positions:
* Lead Software Engineer – we're looking for a strong technical leader to drive one of our product squads. You'll shape architecture, mentor engineers, and ship meaningful product improvements.
* Senior Software Engineer – we're looking for a senior engineer who's excited to own problems end-to-end, from product design through to production.
* Analytics Engineer (Fixed Term Contract) – we're looking for someone to own and improve our analytics models and datasets end-to-end, covering a period of parental leave.

Fully remote, fully async, fully open-source. A CRE is a point of contact available, both internally and externally, to advise on best practice. Normally, they are knowledgeable in a specific area (i.e. Realtime, Postgres) but they aim to be generalists on the platform as a whole. They do not have specific customers that they help; instead they get involved with deeper, longer-running cases to achieve an outcome.
Looking for more of a focused development role? Sure thing, we have many roles open!

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.
Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

We build real-time civilian threat intelligence for conflict zones — and we just landed our first operational pilot. Multi-model AI pipeline (Gemini 3 Pro / Flash) ingests OSINT from verified sources, runs it through a gated verification system, and pushes geolocated alerts to offline-first mobile clients. Think of it as a personal intelligence analyst for non-combatants — on a phone that works on 2G.
This is not a pitch deck. We have a working system: Django backend is live, Flutter apps are approved on both App Store and Play Store, multi-gate AI pipeline is processing real OSINT, admin console has human-in-the-loop verification for high-severity alerts. Since our last HN post: 93 candidates vetted across two months, 1 Senior AI/Backend Engineer hired (now owns the verification pipeline), and we've begun an operational pilot with Winrock International for counter-trafficking intelligence in Southeast Asia. Pre-seed is imminent with multiple NGO grant applications under review (WFP, IRC Airbel, DRK Foundation).
*We need one person:*
*Founding Product Engineer / Systems Architect* You will own the Django backend, MongoDB schemas, and the Flutter UI that connects them. Our AI pipeline lead handles the Gemini orchestration — your job is to own the data layer, build the API surface, and wire it directly into the offline-first client. This is not drawing backend diagrams. You must be an end-to-end builder who cares about how a civilian interacts with the system on the ground in a crisis. A bug in this system isn't a 500 error — it's a missed warning in a conflict zone.
Must have: Python/Django, MongoDB, Flutter (or high competence to pick it up fast), and system design thinking. Strong plus: DevOps (Docker, AWS), LLM integration, OSINT, geospatial.
We also welcome strong full-stack implementation engineers who ship fast and want founding-team equity. Same stack.
*Compensation (No BS):*
- Now: Sweat equity (12-18% SA / 5-10% FSD, 4yr vest, 1yr cliff). This is founding-team ownership. - Pre-Seed (closing): $3,000/month + equity. - Seed (6-12 months): 75% market salary + equity. Increases from there.
If you need full salary today, this is not for you. If you want to build something where the stakes are real and you're willing to bet on yourself to get there — we should talk.
*Stack:* Python 3.9+, Django 4.1.13, MongoDB, Flutter, Vertex AI (Gemini 3 Pro Preview / 2.5 Flash / 3 Flash Preview), Docker, AWS.
*Apply:* Email PeterJFrancoIII@gmail.com with subject line `[SENTINEL-BUILDER] - HackerNews Application`. To prove you read this, include the word "Atlas" in your first sentence. Include your Resume or GitHub + what you'd build in your first week. (Emails without the exact subject line are auto-archived.)
Join HIFI Labs and work on innovative projects with well known and iconic musicians. Past artist activations include Bruno Mars, Linkin Park, Jisoo / Zayn,Rüfüs Du Sol, Dua Lipa, and Mike Shinoda. We're looking for a Senior Fullstack Engineer passionate about design, user interactions, and privacy.
You'll work with TypeScript, React/Next.js, Firebase and explore new frameworks like Astro. Experience with Styled Components, continuous deployment and devops is a plus. We also play around with React Native / Expo.
