The posting

ABOUT THE ROLE

Join a small, fast-moving engineering team building voice AI agents for customer-facing workflows. You will own projects end to end, working across applied AI, real-time audio, and distributed systems to solve practical customer problems.

WHAT YOU'LL DO

- Build reliable voice AI systems, including retrieval-augmented generation, dynamic model routing, and testing transcription services before production rollout.

- Design and operate a distributed call scheduler that manages concurrency, race conditions, time zones, retries, and provider limits.

- Extend agents across voice, messaging, and email, with shared memory and state for asynchronous and real-time conversations.

- Develop memory and reasoning systems that preserve context throughout customer workflows.

- Build AI-assisted tools for configuring agents, debugging issues, and connecting to business systems such as CRMs, calendars, and email.

- Improve tracing and resilience so failures across calls, workers, and providers can be diagnosed and handled effectively.

WHAT WE'RE LOOKING FOR

- Production experience building and owning distributed product systems, and a track record of shipping projects end to end.

- Experience with Python, FastAPI, or TypeScript in production, plus PostgreSQL, Redis, or comparable data stores.

- Background in real-time systems, audio processing, or voice infrastructure, and experience with concurrency, load balancing, or fault tolerance.

- Experience shipping LLM, AI model, or agentic systems, and working with AWS, GCP, or Azure.

- Familiarity with workflow orchestration or message queues, observability tools, and full-stack development is useful.

- Technologies include LiveKit, Bun, Node.js, Fastify, React, Temporal, and OpenTelemetry.

- Strong software fundamentals, independent problem-solving, and a team-oriented focus on customer and business outcomes.

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.
