Ask HN: Who is hiring? (September 2026)

QUOBYTE | Berlin, Germany | Full-time | ONSITE (Germany) | https://www.quobyte.com/ At Quobyte we are working on a highly scalable and fault-tolerant software storage system built around a parallel file system core. Our customers use us for large scale AI and HPC clusters in the enterprise and research, k8s and OpenStack infrastructures, and as a scalable backend for SaaS products. There are Quobyte clusters which span tens of thousands of machines and slurp 100s of GB/s! Under the hood, we have built a full-stack fault-tolerant parallel file system, with everything from kernel development over our own replicated database system design to distributed algorithms (Paxos!) and performance. In short: lots of real-world challenging and fun problems! We work as a highly efficient engineering team, ship frequently, do code reviews, and have lots of unit and integration testing. If you’re passionate about systems, we might be the right place for you! Berlin, Germany (Onsite): * Software Engineer (with a passion for Systems, 60-100k EUR) * Infrastructure Engineer (engineering and corporate infrastructure, 50-90k) * Customer Success Engineer (50-90k) For detailed job descriptions please and application process, please visit https://www.quobyte.com/company/careers or write to work at quobyte.com.

PlantingSpace | Full-time | Remote (EU time zone) + Quarterly Meet-ups | https://planting.space We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics. We're hiring for the following openings: * Engineering Program Lead * Backend Software Engineer * Quantitative Modelling Engineer * Bayesian Software Engineer * Program Synthesis Engineer * Analytic Learning Algorithm Researcher * Product Managers and Business Development * Domain Experts - Valuation, Quantitative Default-Probability, or Interest Rate Prediction Models: to collaborate on use cases, from opportunity validation through production We’ve recently released a series of recordings from one of our quarterly team retreats, to share a look into how we work, and some of the technical problems we’re solving. A few team members sat down and talked through these topics, unscripted, and real. If you consider applying to join us, they offer a glimpse into our culture, and what working with us is really like.

Wikimedia Foundation | Lead Product Manager, Security | REMOTE (US + 18 countries) | Full-time I lead the security and safety team for Wikipedia, at the Wikimedia Foundation. I’m hiring a product manager to lead our security roadmap and steer the priorities of our security engineering team. It’s a high-pace, shipping-heavy time for the whole project right now, as we are dedicating ourselves to surviving all the ways AI is messing with us and the internet, and getting to the other side of it. I joined myself about a year ago, and have found it to be a great time and place to swing big and surprise people. This is a PM role and PM background is certainly helpful, but it’s not strictly required (everyone has the first PM job at some point). A technical background and security expertise are a must for this role, so we’re also open to people in engineering roles, who have demonstrated PM-relevant skills and are interested in making a pivot. You can apply at https://job-boards.greenhouse.io/wikimedia/jobs/8140060?gh_s... - we don’t auto-filter based on AI or anything like that, I will personally see your resume.

Paul Scherrer Institut (PSI), Switzerland | Software Scientist / Research Software Engineer | ONSITE (CH) | Full-time | 2y project | www.psi.ch PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges for society, science and economy. We are looking for a developer for the measurement orchestration software for experiments at the Swiss Light Source (SLS) synchrotron. Our scientists rely on this software for time-critical experiments, requiring support before, during, and after measurements to use, extend, and integrate new functionality. The role acts as translator and facilitator between scientists and specialists across a wide range of disciplines, bridging gaps in collaborative discussions and code development.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite We make robots that autonomously construct buildings, starting with bricklaying. There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run. We're looking for experienced software engineers for many roles. You can help us solve problems like: - Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time) - Modelling buildings in code and finding the right UI for operators to edit them - Designing systems for robots to drive safely and fully autonomously around a building site Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium We're rapidly scaling up operations - we'll be building in the UK soon - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!
