Summary
👤
Senior🎓
Top SchoolJeff An is a startup CTO and seasoned engineering leader with 9 years of experience building scalable developer infrastructure and developer-first products. As Co-Founder and CTO of Momentic (YC-backed), he’s focused on bringing no-code visual end-to-end testing to teams while previously inventing Toolscript and a Retool VS Code experience to enable reviewable, source-controllable app workflows. Jeff led large teams at Robinhood to create a Kubernetes production simulation that powered thousands of tests and developer environments, and has a track record of cutting iteration time and infrastructure costs across Google, Splunk, and other scale-stage companies. He combines low-level systems expertise (Kubernetes, Bazel, autoscaling) with product-minded APIs that unlock developer velocity and observability. A Waterloo CS grad and International Chemistry Olympiad medallist, he brings both rigorous analytical training and a knack for translating research-grade thinking into production systems. Based in San Francisco, he mixes hands-on engineering with founding experience and a tilt toward tooling that makes complex workflows reviewable and automatable.
