Job Summary
At Trunk our mission is to help teams create high-quality software quickly. Weve helped engineerings teams at: Google X Zillow and Brex to understand why their builds fail which tests are flaky and how to ship code faster without sacrificing reliability. AI has made writing code 10x faster but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts flaky tests inconsistent code quality and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing implementing and delivering software will build magical high-quality projects - and theyll be happier doing it. Were building a CI Reliability Platform that empowers teams to land code faster and develop happier.
Our founders launched Trunk in 2021 after designing delivering and scaling software at Uber Google YouTube and Microsoft. We raised a $25M Series A led by Initialized Capital (Garry Tan) and a16z (Peter Levine) with investments from Haystack Ventures Garage VC and the founders of GitHub (Tom Preston-Werner) Apollo GraphQL (Geoff Schmidt) Algolia (Nicolas Dessaigne) and(Oleg Rogynsky).
CI pipelines are black boxes. Engineers waste hours debugging failures that turn out to be flaky tests or infrastructure noise. Trunk makes this visible: what failed why and whether its worth fixing.
The next wave is agentic. AI tools today hit a wall when code leaves the local environment. Were building the data layer that lets AI agents actually reason about CI: diagnosing failures suggesting fixes and eventually shipping code autonomously.
Were looking for a Tech Lead to own the data platform that powers Trunks flaky test detection and CI analytics products. Youll design and build the systems that ingest millions of test runs per hour surface actionable insights and lay the foundation for AI-driven CI workflows.
Were at an inflection point. The scale challenges are real and growing. The AI/agentic future of development tooling is taking shape and were building the data infrastructure that makes it you want to work on hard systems problems with direct customer impact this is the role.
What youll do
- Design and build the data pipelines storage systems and backend services that power Trunks flaky test and CI products
- Lead a team of engineers through complex distributed systems and data infrastructure challenges
- Work directly with customers to understand their pain points and translate them into robust technical solutions
- Drive architectural decisions for scale reliability and future AI/agentic integrations (MCP semantic failure clustering automated remediation)
- Ship independently with high autonomy. Were a small team solving hard problems and youll have significant ownership
Were looking for
- 7 years of backend/infrastructure engineering experience with a focus on data processing pipelines and distributed systems
- Experience leading teams of 2 engineers on complex technical projects
- Track record of building and operating systems at scale
- Strong proficiency in Rust and Python; familiarity with TypeScript
- Experience with our stack: PostgreSQL ClickHouse AWS Kubernetes Dagster
- Comfort with monitoring observability and debugging in distributed environments
- Previous experience at a high-growth startup
Youre a good fit if ℹ
- Youre passionate about building high-quality scalable systems and take pride in clean maintainable code
- You have deep experience with distributed systems databases and performance optimization
- Youre comfortable navigating large codebases and can ramp quickly on complex systems
- You enjoy mentoring engineers and thrive in collaborative environments
- Experience and intuition to zero in on root causes for bugs that can leave others stumped
- Youre self-directed making sound technical decisions without waiting for detailed specs
