  • Add a new information source to the platform on day one.
  • Ship a speed or reliability improvement to agentic systems in week one.

Requirements

  • 2 to 7 years of professional software engineering experience with a strong track record of building, shipping, and operating production systems end to end.

  • Data infrastructure and pipeline experience, including ETL, data modeling, and SQL.
  • PostgreSQL or similar relational database design and optimization.
  • AWS cloud infrastructure and deployment experience.
  • Production observability, monitoring, and debugging of distributed systems.
