Research Engineer (Reinforcement Learning)
LiveKit, North America +1
The role
We are looking for an exceptional engineer to build post-training at LiveKit. Our agents run over voice and increasingly over text channels like SMS and chat, and the interesting problems show up over long horizons: staying useful across many sessions, working with context that accumulates over time, and using tools reliably in the middle of a live conversation.
What you will do
- Build the environments and verifiers our models train against
- Own the synthetic data pipeline, from generation through the quality gates
- Run training experiments end to end, and explain what moved the model
