We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams - even if you aren't a 100% skill or experience match. Here are a few qualities we've found compatible with our team. If some of this describes you, we'd love to talk. * You want the people using your software to be people you know by name, and you take it personally when it gets in their way * You want a product area that is yours to own end to end, from the first conversation with a user to the thing running in production * You work well at speed. Priorities here move with the business, and the problems worth solving tend to arrive on short notice * You want to know whether the AI in your product is any good, and you will build the evals to find out * You stand behind what you ship, whether you wrote it or a model helped you write it ## Description You will build full-stack applications, and features in UNION itself, and own all of it in production, from the interface down to the data model. Our stack is TypeScript with React and Next.js, Python services running on Kubernetes, and Postgres alongside the lakehouse. We care more that you have built and run this kind of software than which frameworks you built it in. A good share of the work is AI-facing, meaning natural language interfaces and agents that operate on governed data, plus the evaluation work that tells you whether they are any good. Owning a product area here means you sit with the people who run the process and work out with them what the software should do. You are also the one who answers for it when it breaks. Most of these processes have never been written down anywhere, so a fair amount of the job is working out what to build before you build it. ## Related Videos - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Building the Next Generation of Software](https://www.wearedevelopers.com/videos/100186-building-the-next-generation-of-software) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Craftsmanship in the Age of Agents](https://www.wearedevelopers.com/videos/100106-craftsmanship-in-the-age-of-agents) ## Related Articles - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [What is Software Engineering in the Age of AI?](https://www.wearedevelopers.com/magazine/640-what-is-software-engineering-in-the-age-of-ai) - [Never delegate the understanding](https://www.wearedevelopers.com/magazine/749-never-delegate-the-understanding) - [How to Answer the Interview Question: “Why Do You Want to Be a Software Engineer?”](https://www.wearedevelopers.com/magazine/392-how-to-answer-the-interview-question-why-do-you-want-to-be-a-software-engineer) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again)
