  • [Optional] Expand features and improve the reliability, accuracy, and speed of our LLM orchestration.

  • Deep understanding of backend development best practices, including system design, performance optimization, async frameworks, and scalable architecture.
  • Take initiative and get things done.
  • Quickly evaluate tradeoffs and make sound technical decisions in a fast-paced, changing, and often unclear environment.
