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 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.

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.)

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 build and deploy self-driving industrial vehicles - forklifts, tuggers - to real warehouses and factories across North America. Not a research lab, not a demo: our AVs are running production routes at customer sites today. Publicly traded (CYN), ~100 people, startup energy.
The stack touches everything from low-level C++/ROS2 on the vehicle to a Python + TypeScript cloud platform (fleet dashboards, real-time telemetry, digital twins, analytics). If you want to work on software that moves physical things in the real world, this is it.
Currently hiring across engineering, product, field ops, and business:

We have a ton of smart people trying to solve the autonomy problem in warehouses for retrofitting processes. Come and join!
We are hiring two Product Engineers to join us in our newly opened office in SF. We're small and early and you'll help shape team culture.
Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured.
Our #1 hiring criteria for this position is immense software wisdom, the kind not yet encoded in the weights of an LLM. We are not looking for artisans to meticulously craft single lines of code. We're looking for software engineers excited to use the leverage that AI offers for code production to permit focus on higher order technical architecture, product requirements, and user needs.
We're looking for enough experience that indicates accumulated wisdom in shipping and maintaining reliable, scalable software, solid CS fundamentals, experience taking products from 0 to 1, and versatility.
Our current tech stack includes TypeScript, a managed container service, Postgres, and Redis. But we are adaptive and you should be too. We highly value software engineering and computer science fundamentals and experience with other languages like Go, C++, Python is valued.
Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m).

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.

- 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.

You’ll work on the projects best suited for you. Projects range widely, and include:
- Scientific tools
- Automation & robotics (Linux & ROS level)
- Embedded C/C++ (typically owned by dedicated firmware engineers, but software engineers are welcome to learn!)
- Linux, CUDA, Server engineering for our AI safety, security, and verification work
- Custom simulation software (usually python)

- Organisational tooling (Typescript, react, postgres, etc.)
Structure: Small teams of software, mechanical, electronics, and firmware engineers build end-to-end systems, typically shipping within a few months.
Looking for experienced engineers to build and scale infrastructure and data platforms for a Berlin asset management fund. We are betting big on AI to drive investment returns and build the best infrastructure to support our high alpha targets (track record >30% p.a. since inception; https://bitcap.com/en/bit-global-technology-opportunities-ai...).
You'll design large-scale data pipelines, evolve our lakehouse architecture, strengthen data quality and observability, and build infrastructure for AI/LLM workflows (agentic scaffolding, RAG, LLMOps, AI for engineering). We are looking for a hands-on technical leader, that is steering initiatives end-to-end while staying deep in implementation.
We have our roots in tech entrepreneurship (Jan Beckers), and this mindset still dominates our work culture, even as a regulated financial institution. We are a team of ~40 with a flat hierarchy, hands-on leadership, fast-paced decisions, and a little nerdy culture as people are actually passionate about their work. Stack: AWS, Databricks/Spark, Python, PostgreSQL, Agentic AI.
If the complexity of financial markets excites you as much as the complexity of distributed systems, you'll love it here. Competitive comp, relocation & visa support, stellar team.
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.
