The ideal candidate will have a passion for developer tools, extensive knowledge of diverse programming environments and languages, and experience with advanced LLM features like tool-use, chaining and orchestration patterns, and prompt engineering. Curiosity about AI research is a must. We believe new AI capabilities are best achieved through secure foundations, and as capabilities grow more advanced, it is critical that progress moves forward safely and for the benefit of all society.

  • Dive into possibly unfamiliar areas like Python notebooks, VS Code plug-ins, and containerized environments.

Requirements

  • Excited about AI-assisted coding as a tool to enhance developer productivity and creativity.
  • Spend a lot of time refining and customizing AI workflows.

  • Specializes in user experience engineering but is a capable full stack developer.
  • Hands-on experience working with large language models and prompt engineering.
  • Worked on projects with stringent safety, security and/or compliance requirements.
  • Care about the societal impacts and ethics of your work.
  • 6+ years of work experience.
  • Building and maintaining CLI tools.
  • Working in large codebases and quickly jumping in to unfamiliar development environments.
  • Working with container orchestration and cloud infrastructure.
  • Scaling TypeScript projects.
  • Working with alternate JavaScript runtimes like Bun and Deno.
