Product Engineer

Ojin | Product Engineer | HYBRID (Berlin) or REMOTE (CET ±2h) | Full-time Hi HN! I'm Seema, Tech Recruiter at Ojin, and we're looking for another 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 5+ years proving this works for enterprise customers and we're now opening it up as a developer platform. 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 genuine curiosity about how AI systems actually work in production. We're not able to offer visa sponsorship or relocation support for this role - you'll need to already be based within CET ±2h and have the right to work where you live.
