About the role

More and more developers don't read our docs or click through our dashboard. Their coding agent does. Claude Code, Cursor, Codex and others are now how a big share of engineers discover, integrate and debug AssemblyAI. We've spent years polishing the human experience. The agent experience (AX) is newer, growing fast, and almost untouched. Found on 1752vc Careers, the job board for startup and VC roles.

What they're looking for

  • 2+ years of professional software engineering experience, with solid full-stack fundamentals (Javascript and/or Python)
  • Daily, hands-on use of coding agents such as Claude Code, Cursor or Codex, and real curiosity about what makes them succeed or fail
  • Some hands-on experience writing prompts, skills, tool definitions or agent instructions, at work or side projects, and an interest in measuring them with evals rather than vibes
  • Product sense for developer-facing work. You care whether the developer, or their agent, actually gets to a working integration
  • Clear technical writing. Much of this role is writing that agents and humans both read
  • Comfort with ambiguity and a bias to ship. AX is a new discipline, and you'll learn it and help define it alongside us
