About the role

Notion is seeking a Software Engineer to join the Model Capabilities team, responsible for integrating frontier models, ensuring scalable and reliable inference, and building model-level capabilities for Notion AI.

Responsibilities

  • Bring new frontier models into production quickly, making them available for our users and our engineers.
  • Make inference reliable: better error categorization, self-healing retries, and cross-provider failover.
  • Own observability for the model layer, driving down both time to detection and time to fix.
  • Build new model-level capabilities and help product teams adopt them.
  • Act as connective tissue across Notion's AI teams: find the gaps, unblock people, and make sure fixes land with the right owner.

Qualifications

  • Comfort with a moving frontier: The model landscape changes monthly. You keep up with it, form your own view of what's real, and stay pragmatic about what's worth adopting now.
  • AI fluency as a practitioner: You use AI tools seriously in your own work and have opinions about where they help and where they don't.
  • Production AI systems experience: You've built and operated systems on top of LLM APIs, you understand token economics, streaming, tool calling, context limits, and production failure modes.
  • Measurement before conviction: You define what 'better' means, use evaluation to test it, and are willing to be proven wrong by data.
  • Cost and performance instincts: You treat latency and dollars as product qualities, balancing them with output quality.
