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.
Come take a look at our open roles: https://www.thirdfort.com/jobs/
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.

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
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.

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.
On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.
Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.
If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

The AMF works to fight malaria in an extremely cost effective way with insecticide treated bed-nets. Every year hundreds of millions of people will be infected with malaria, and half a million of them will die, with many more being debilitated or disabled. Independent charity evaluators, such as GiveWell, have ranked the AMF as one of the most cost-effective charities in the world for over a decade, due to our long and well-studied track record preventing hundreds of millions of cases of malaria.
Our tech team is just a couple people, and all-remote. Our software is essential to the charity work we do; it is one of the ways we stand out among other charities, by allowing us to automate, analyze, and validate our work in novel ways. Our tech stack includes C# .NET, Blazor, and Python.

We build an open source data platform on Kubernetes. The product (Stackable Data Platform - SDP) bundles 12+ open source data tools (Trino, Apache Kafka, Apache Airflow, Apache Superset, etc.) and makes them work together. Right now everything is Infrastructure-as-Code only. We need someone to build a UI layer on top.
No mockups, no Figma, no product roadmap waiting for you I'm afraid, just a bunch of ideas :) We're all backend people and need someone to own this end to end. Play around with our product stack, figure out what customers actually need, build it.
Stack (because we got started without you...): Svelte/SvelteKit, TypeScript, TailwindCSS. SDP itself is Rust, Java, Python on K8s. Three releases a year. Not SaaS. Quality matters.
100% remote, Germany (UK possible) only, no other countries, sorry. No Scrum, minimal meetings. Interview process is usually just two conversations. The position isn't on our homepage yet as I'm on vacation. Send a mail to recruiting@stackable.tech and I'll get back to you next week. Please mention HN in your mail. My personal mail is also in my HN profile. I'm the Co-founder and CTO.

We have a ton of smart people trying to solve the autonomy problem in warehouses for retrofitting processes. Come and join!
We'd like to feed the world through AI, here is our product concept:
https://taonexus.com/publicfiles/mar2026/render%203-2.webp
https://taonexus.com/publicfiles/mar2026/render%204.webp
We currently donate money to food banks and would like to set up end-to-end infrastructure so we could deliver free food to people's homes. Our concept is that AI does all the work (including farming) and gives away free goods and services. Where this runs into problems is the question of who's going to make and distribute food and how people are going to get it. While we haven't figured out all parts of food delivery we'd like to work on the distribution channel. We think it's very important.
What we're looking for is someone who is passionate about owning network infrastructure in people's homes and would like to help run the software stack, since at the moment AI is not talented enough to autonomously run the full infrastructure stack. This is an unpaid volunteer position.
What you would be in charge of is food distribution algorithms, equality, fairness, and the long-term future for humanity.
You can email me directly at: rviragh@gmail.com - please mention relevant volunteering or organizations you support.

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.

Identity Labs has generated 2B+ views across Twitter. We've worked with Bryan Johnson, Chamath Palihapitiya, Tony Fadell, partners at a16z, partners at Kleiner Perkins, and YC founders. We are a small team of 15 people.
If the 21st century gets defined by 100 influential ideas, Identity Labs wants to be instrumental in popularizing 10 of them.
We believe every founder who's built something massive has five Paul Graham level essays inside them. Our job is to find those essays and give them distribution.
We're hiring a Creative Director.
Your job is to sit with someone who built a billion dollar company, talk for two hours, figure out which idea from that conversation will make 10 million people stop scrolling on Twitter, then write it.
It's intellectual sparring plus longform journalism plus an obsessive understanding of what spreads on Twitter and why.
We're growing at 1500%+ YoY. A Creative Director can 5x their salary within 2 years as they grow into a Partner role.

* Backend Software Engineer (Python, PostgreSQL/PostGIS, Docker, AWS, Terraform) - $135-$155k — https://enveritas.org/jobs/backend-software-eng/#10d7adef8us (worldwide remote)
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!

Ridgeline International builds software that fights Ubiquitous Technical Surveillance (UTS), which is the growing threat of everyday commercial devices, apps, and networks being used to passively collect data on people and organizations without their knowledge. Think smartphones, smart TVs, IoT devices, and third-party apps leaking sensitive behavioral and location data at scale. Our tools help U.S. government and enterprise customers understand and manage that exposure, often before they even realize they have a problem.
This is a genuinely full-stack role. You will own features from design through deployment, working with Java (backend), Angular (frontend), REST and GraphQL APIs, SQL databases, and cloud infrastructure with DevOps workflows. For the first four months you will support legacy systems built on C# and Azure, then transition to our modern core platform. That bridge phase is intentional, not a bait-and-switch.
What you need:
U.S. citizenship required, ability to obtain a security clearance 5 or more years of professional software development Strong OOP fundamentals and relational database experience Comfort with REST APIs and a genuine growth mindset
Bonus if you have: Java or Angular experience, GIS or mapping work, DevOps and CI/CD, or containerization (Docker, Kubernetes).
Perks include flexible PTO, a generous 401k match up to 10% with automatic 3% safe harbor, full health benefits, HSA employer contribution, professional coaching, and personal privacy protection services.
We are the hiring company, not a recruiter.

We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

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.
