About Asteroid

Asteroid builds AI browser agents for enterprise operations teams. Their agents run directly in the browser — no APIs, no connectors — automating mission-critical workflows like prior authorization, insurance quoting, and patient data entry at scale. Founded by David (CEO) and Joe (CTO), the team was first to deploy computer-use agents to healthcare and processes thousands of browser agent executions daily. Backed by Y Combinator (W25) and Entrepreneur First, with angels from OpenAI and Hugging Face.

About the Role

Asteroid processes thousands of mission-critical browser agent executions per day — and the interface for supervising them has never been built before. You'll own the entire product experience end-to-end: design system, onboarding, core frontend features, and the website. This isn't a maintenance role — you're creating the UX paradigm for what it means to supervise an AI workforce at scale across complex, exception-heavy workflows. The team is world-class at AI and infrastructure. What's missing is someone with taste.

Requirements

  • Proven experience building and shipping products used by thousands of weekly active users, ideally B2B
  • Full-stack engineering capability — you don't stop at the frontend
  • Ability to translate customer feedback into specific, high-impact platform improvements
  • Incredible taste — a perfectionist who knows when to ship
  • Self-motivated, hard-working, and extremely AI-native
  • 3+ years of relevant experience

Nice to Haves

  • Design background — Figma fluency and visual design chops
  • Strong AI engineering skills
  • PM-like instincts — can run a roadmap, not just execute on one
  • Experience managing customer accounts directly

Benefits

  • Contract-to-hire path (full-time or part-time)
  • Work alongside the full team in SF, ideally in person
  • Greenfield ownership — no legacy codebase or design system to inherit

Compensation Details

Salary $130K–$160K. Equity 0.20%–0.40%. Contract-to-hire path available. Standard 4-year vest with 1-year cliff assumed.
