Sourced from bookingagency.io
Superhuman is looking for a back-end software engineer to build LLM-powered, agentic AI features end-to-end. The role involves designing reliable, fast, and scalable services, protocols, and data flows, taking ownership of ambiguous problems, and shipping in tight iterations. The ideal candidate is back-end-strong yet stack-flexible, with hands-on experience integrating LLM/agentic features and strong fundamentals in Java, Go, or Python. This hybrid role is based in Berlin and includes relocation support.
Responsibilities
- Build LLM-powered and agentic AI features end-to-end, from idea to production.
- Design services, protocols, and data flows that make AI features reliable, fast, and scalable.
- Build and support production services with high call rates, targeting high availability.
- Take on ambiguous problems—shaping scope, estimating work, and making quality, cost, and latency trade-offs.
- Move across the stack when needed, from client platforms to shared protocols to infrastructure.
- Learn infrastructure as code and ship in tight iterations.
- Mentor new hires and help raise the engineering bar across the team.
Requirements
- 5+ years of relevant experience in back-end development.
- Back-end-strong but stack-agnostic, comfortable working across the stack.
