Job description

About the Role

Join a small engineering team building voice AI agents for customer-facing business workflows. You will own projects from product decisions through architecture and production delivery, helping make real-time AI interactions reliable and useful.

What You'll Do

  • Build reliable voice AI systems, including retrieval-augmented generation, dynamic model routing, and testing new transcription systems before release.

  • Design and operate distributed call scheduling systems that handle concurrency, time zones, retries, provider limits, and failures.

  • Extend agents across voice and other communication channels, maintaining shared context across real-time and asynchronous conversations.

  • Develop memory and reasoning capabilities that help agents maintain context through customer workflows.

  • Build AI-powered tools for configuring agents, troubleshooting issues, and connecting to business systems.

  • Improve observability and resilience so issues can be traced to their root causes.

What We're Looking For

  • At least 2 years of relevant experience building and shipping product software, including owning distributed systems in production and delivering projects end to end.

  • Production experience with Python, FastAPI, or TypeScript, and data stores such as PostgreSQL or Redis.

  • Experience with distributed systems, real-time systems, audio processing, voice infrastructure, or production AI and agentic systems.

  • Familiarity with cloud infrastructure such as AWS, GCP, or Azure.

  • Experience with workflow orchestration or message queues, frontend development, and observability tools is useful.

  • Strong software fundamentals, a bias toward action, and an interest in business outcomes and reliable AI products.

  • Relevant technologies include LiveKit, Bun, Node.js, Fastify, React, Temporal, and OpenTelemetry.

Compensation & Benefits

Base salary is €85,000 to €160,000 annually, plus equity. Visa sponsorship is available.

Location

On-site in Berlin, Germany.
