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’re Quadrature, a technology company in the algo trading space. We use advanced machine learning on large amounts of data to predict trends in financial markets. More at https://quadrature.ai.
What makes us different:
- ~250 people, no traders — our systems trade autonomously.
- Single PnL.
- We don’t separate “quant researchers” from “developers” — everyone codes to a high level and has the opportunity to do research.
- Mission-driven: our climate foundation (https://www.qc.foundation/) has made significant divestment commitments over recent years. For many of us, it's why we're here.
We’re hiring Quant Developers — a generalist team of engineers and researchers who own both the research pipeline and software infrastructure across the entire business. Stack is Rust, Python and C++. We want sharp, collaborative people with no big egos.
Interested? Reach out here: li@qc.ai.

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.

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!

Fractional AI operates at the forefront of applied AI, and we measure our success by the business outcomes we deliver in production — not by checking boxes on a SOW. We build production-grade AI systems that optimize core operations, automate internal workflows, and improve customer experiences. Every system is designed explicitly against clear business goals and North Star metrics (revenue growth, cost take-out or avoidance, churn reduction, etc.). Our role is to enable our customers to get past POCs and experiments into robust, real-world systems that reliably create value.

Tables power every clinical trial, financial model, and scientific experiment, but deep learning has mostly ignored them. No natural sequence, no spatial structure, no shared vocabulary across datasets. LLM architectures don't transfer. We built TabPFN, the first foundation model that actually understands tabular data (published in Nature, 3M+ downloads, new SOTA for tabular ML). The hardest problems are still open.
The model is half the product. The other half - training infrastructure, real-time serving, developer platform, reliability - is what turns a research breakthrough into something enterprises trust in production. We're hiring across both.
- ML Engineer, Training Infrastructure — Own GPU infrastructure, distributed training performance, and the developer productivity layer (CI, experiment tracking, model registry) that keeps research moving fast.
- Full Stack Engineer, ML Platform — Build the product that puts tabular foundation models in users' hands, from data upload through inference and results. You'll work across frontend, backend, and directly with the research team to turn new model capabilities into production features.
- Research Engineer, Foundation Model — Design experiments, run ablations, build training infrastructure, contribute to papers. Research engineers here aren't supporting scientists — they are the science team.
- ML Engineer, Cloud Platform — Design and scale the core infrastructure for serving and finetuning foundation models in production. Early enough that you're making the architecture decisions, not inheriting them.
Also hiring: Research Scientist, Applied Scientist, Forward Deployed ML Engineer, Developer Relations Engineer, AE, BDR.
20-person team selected from thousands applicants. Backgrounds from Jane Street, Google, CERN, G-Research. Led by Frank Hutter, advised by Yann LeCun and Bernhard Schölkopf. With backing from leaders at Hugging Face, DeepMind, and Black Forest Labs, XTX Ventures & Balderton.

Rinse provides dry cleaning and laundry delivery services to customers in twelve metropolitan areas in the US and Canada. We have sophisticated logistics optimization software, a polished consumer product, and firm business fundamentals. We're now over a decade old - this is a stable, yet consistently growing and innovating, company.
Our engineering team is distributed across the United States and internationally, and has been entirely remote for years now, but a desk can be provided in the above cities if you'd prefer.
We're open to both newly-graduated engineers or more senior engineers, provided they meet our bar. We're particularly interested in true full-stack engineers, with strong React / Typescript / CSS skills to complement comfort in a Python / Django environment. We're also seeking engineers with experience leveraging AI to automate complex operational processes.
This season, we're particularly interested in new grads or junior engineers, to round out the team.
You will join a high-caliber team where collaboration, honesty, and open communication are at the core of everything we do.
