Urun - Founding Engineer- Software

• 7+ years building and shipping backend software in production • Proficiency in one or more backend languages — Python, Go, or TypeScript/Node.js • Experience designing APIs, service-oriented systems, and distributed application components • Solid understanding of cloud infrastructure, containers, and modern deployment workflows • Ability to reason about performance, concurrency, reliability, and debugging in complex systems • Experience with real-time, interactive, streaming, or latency-sensitive systems, this is central to the role, not a bonus • THINGS THAT WILL GIVE YOU AN EDGE • WebRTC or WebSockets for real-time communication • AI infrastructure, inference-adjacent systems, media pipelines, or event-driven architectures • Kubernetes, observability tooling, and hands-on production operations • Early-stage startup experience — owning problems end-to-end and moving quickly with limited scaffolding • WHAT YOU'LL GET IN RETURN • Competitive salary and meaningful equity in an early-stage AI infrastructure company. The band above is our target; for an exceptional candidate we'll go higher. Equity is real — you're early, and the grant reflects that. • Health, dental, and vision — full coverage • 401(k) — company-supported retirement savings • FSA/HSA — flexible spending accounts for healthcare costs • Paid time off — we trust you to manage your time • Top-tier tooling — access to the best AI tools available: Claude, Codex, Kimi, and whatever else helps you move faster • MacBook Pro and AirPods — the hardware you need, on us • HOW WE WORK (AND WHAT THAT FEELS LIKE DAY-TO-DAY) • You'd join an early team building a genuinely new category of real-time AI infrastructure and product. You'd work directly with the founder and senior technical leadership, with real influence over architecture, developer velocity, and the shape of the product itself, working at the intersection of backend systems, platform engineering, and interactive AI. • It also means ambiguity. We're early: there's limited scaffolding, priorities shift, and you'll often be setting architecture before there's a playbook to follow. That's a real part of the job, and it suits some people far more than others. We'd rather you know it going in. • We build the stage, not the show. We're an infrastructure company, a developer-tools company, and a production partner for model labs, and focus is a deliberate choice we've made and hold to. • Day-to-day, that means a small team, a high bar, and real ownership. You won't wait for permission or inherit a backlog of someone else's decisions, in a founding security role, the function is what you make it. • Watch our launch party video https://www.linkedin.com/posts/whatcanurun-ugcPost-7460358302183596032-Yhde?rcm=ACoAACk3J5EBo0AnESrfELpk5q0Fzw2bm2AHvq8&utm_medium=member_desktop&utm_source=share • Read the manifesto https://blog.urun.sh/ • Follow us on LinkedIn https://www.linkedin.com/company/urunml/ • Follow us on X https://x.com/urunml
