Senior Software Engineer; Platform

At Trunk, our mission is to help teams create high-quality software quickly. We've helped engineering 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 they’ll be happier doing it. We’re 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, You Tube, 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 Git Hub (Tom Preston‑Werner), Apollo Graph

QL (Geoff Schmidt), Algolia (Nicolas Dessaigne), and Peopl.ai.
