Hi HN! I'm Seema, Tech Recruiter at Ojin, and we're looking for a Product Engineer to join our small team.
We build the infrastructure that makes AI feel human — real-time AI agents with natural, lifelike conversation on a globally distributed GPU fabric. We've spent five years proving this works for enterprise customers and we're now opening it up as a developer platform — this is the team that will build it from the ground up.
You'd own features end-to-end: interactive frontends through to Python-based agentic backends, working directly with the founders on a 15 person team. You help define the solution, design the architecture and ship it.
Stack: TypeScript, React, Node.js, Python, WebRTC, WebSockets, AWS
Looking for: 3-5+ years, genuine full-stack ability, startup experience, and real enthusiasm for building AI products.
We're not able to offer relocation or visa sponsorship. If you're already in Berlin, this is a hybrid role. If you're elsewhere, we're open to fully remote within CET ±2h.
