About the role

Role focused on building and improving the agent experience (AX) for AssemblyAI, enabling AI agents to integrate with AssemblyAI products. Owns agent skills, MCP server integrations, documentation, prompts, and evaluation to achieve production-ready integrations for developers.

Responsibilities

  • Drive the agent experience. Treat coding agents as a first-class user of AssemblyAI, alongside the humans who use our dashboard and Playground.
  • Build and maintain agent skills. Ship skills for our core products (Speech-to-Text, Real-time, Dictation, Voice Agents, TTS, LLM Gateway) that teach agents how to integrate us correctly.
  • Build on our MCP server and agent integrations. Extend the AssemblyAI MCP server, help ship agent and MCP auth (OAuth and API keys), and make it easy to plug into Claude Code, Cursor, Codex and whatever comes next.
  • Make our docs and code samples agent-ready. Own llms.txt, machine-readable docs, quickstarts and SDK examples so agents pick the right API, parameters and patterns the first time.
  • Tune the prompts and instructions behind our product. Improve the system prompts, tool definitions and agent instructions that power our in-dashboard agent and onboarding flows.
  • Measure it. Build evals and benchmarks that run real coding agents against real integration tasks. Track success rate, time to first working call, and activation from agent-driven signups.
  • Help us scale the playbook. Start with one product and then roll what works across every product.
  • Use AI tools as a core part of how you work, and help the rest of engineering build faster with agents.

Qualifications

  • 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 curiosity about success/failure factors.
  • Hands-on experience writing prompts, skills, tool definitions or agent instructions, and ability to measure them with evals.
  • Product sense for developer-facing work. You care whether developer or agent reaches a working integration.
  • Clear technical writing. Ability to produce content read by both agents and humans.
  • Comfort with ambiguity and bias to ship. AX is a new discipline.
