AI-native devtools that help engineering teams measure and improve how they ship software

Lead Software Engineer - Backend

San FranciscoHybrid$210K - $250K6+ years
You'll spend your days designing data pipelines that ingest messy engineering signals—Git commits, CI runs, incident pages—and transform them into structured insights that managers actually use. Most of your code will ship in TypeScript or Python, though you'll sometimes reach for Go when latency matters. Expect to review a lot of PRs from junior engineers, debate schema designs with the data team, and occasionally debug why a customer's Azure integration is throttling at 3pm on a Tuesday. This is a team that still builds together in person a few days each week in San Francisco and the South Bay.

What they're looking for

  • 6+ years shipping backend systems, with at least two years in a senior or staff role
  • Deep fluency in TypeScript or Python, and comfort reading Go or Ruby when context demands it
  • Experience building on AWS, Azure, or GCP—bonus if you've wrestled with multi-tenant data isolation
  • Track record of mentoring engineers and shepherding technical decisions without micromanaging
  • Genuine curiosity about how software teams work, not just the tools they use
