About the role

This is a small team (3-4 engineers) with high autonomy and broad ownership. You'll work across the full stack as an AI-first generalist who moves between browser-side code, edge runtimes, and backend services depending on what the problem demands. You'll get competitive perks and benefits , from health & wellness to equity, to help you bring your best self to work.

What they're looking for

  • Own data collection across the full stack. Work across the JS tag, Cloudflare Workers, and Java backend services to deliver reliable first-party data collection at scale
  • Help lead technical direction on a small, autonomous team. Write proposals, run design reviews, and mentor teammates. With a team this size, your judgment directly shapes what gets built and how
  • 6+ years of professional software engineering experience, with a track record of working across multiple layers of a system, not just frontend or backend alone
  • Backend experience building and operating services in Java, Kotlin, or a similar typed language, including API design, data modeling, and testing
  • Comfortable with JavaScript/TypeScript beyond casual use. You can reason about browser runtime behavior, async patterns, and performance in production
  • Experience with edge compute or serverless runtimes (Cloudflare Workers, Lambda@Edge, Fastly), or the ability to ramp quickly
