The posting

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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
