Trunk Technologies Inc.
Tech Lead (CI & Test Data Platform)
Trunk Technologies Inc., San Francisco, California, United States, 94199
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, 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 Peopl.ai (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 it's worth fixing.
The next wave is agentic. AI tools today hit a wall when code leaves the local environment. We're building the data layer that lets AI agents actually reason about CI: diagnosing failures, suggesting fixes, and eventually shipping code autonomously.
We're looking for a
Tech Lead
to own the data platform that powers Trunk's flaky test detection and CI analytics products. You'll 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.
We're at an inflection point. The scale challenges are real and growing. The AI/agentic future of development tooling is taking shape, and we're building the data infrastructure that makes it possible. If you want to work on hard systems problems with direct customer impact, this is the role.
What you'll do
Design and build the data pipelines, storage systems, and backend services that power Trunk's 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. We're a small team solving hard problems, and you'll have significant ownership
We're 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
You're a good fit if ℹ️
You're 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
You're 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
You're self-directed, making sound technical decisions without waiting for detailed specs
Our tech stack
Frontend: Typescript, React, Next.js, AWS
Backend: Typescript, Node, AWS
Data pipelines: Dagster, python, polars
CI/CD: GitHub Actions
What we offer
Unlimited PTO
Competitive salary and equity
Work-life balance
Lunch ordered in on us at the office on Wednesdays and Thursdays
Few meetings, so you can ship fast and focus on building
One Medical membership on us!
Top-notch medical, dental, vision, short-term disability, long-term disability, and life insurance
All insurance is 100% company-paid ($0 premiums) for employees and highly subsidized for dependents
FSA, HSA with company contributions, and pre-tax commuter benefits
401(k) plan
Paid parental leave ( up to 12 weeks)
The salary and equity range for this role are: $200-$245K and .3-.5%.
Please note that the compensation range provided is a general guideline only and is subject to change based on location, qualifications, and experience.
Don’t meet every single requirement? At Trunk, we are dedicated to building a diverse and inclusive workplace, so if you’re excited about this role but your past experience doesn’t align perfectly with every qualification in the job description, we encourage you to apply anyways. You may be just the right candidate for this or other roles.
If you need assistance or an accommodation due to a disability, we're happy to help accommodate. Please contact us at recruiting@trunk.io.
