Ojin
Product Engineer | HYBRID (Berlin) or REMOTE (CET ±2h)
hn · HYBRID (Berlin) or REMOTE (CET ±2h)
Jose is a near-perfect match with 12+ years shipping production systems including real-time voice AI products, deep expertise in the exact tech stack (TypeScript, React, Node.js, Python, WebRTC, AWS), and proven founding engineer experience building AI products end-to-end. His work at Addie on real-time voice agents with sub-200ms latency and multi-channel delivery directly aligns with Ojin's core mission, and he has the full-stack capabilities and startup DNA the role demands.
Hook: You've built the exact product Ojin is now productizing — real-time AI voice agents at scale — and you've done it as a founding engineer with the full-stack and architectural ownership they're looking for.
Missing: CET timezone location confirmation (candidate is in California, though role allows remote CET ±2h)

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 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.
