Founding Product Engineer

Weave (YC W25) is building the definitive platform for understanding and improving how engineering teams work.

We’re now hiring a Founding Product Engineer to help define the product and the technical foundation of Weave.This is a rare opportunity to join at the ground floor and shape how millions of engineers and leaders understand engineering work.What We’re BuildingWeave is rethinking engineering output from first principles.We use AI to:Understand how engineers actually work (not just what they ship)Surface meaningful insights about productivity, quality, collaboration and impactHelp teams improve outcomes without vanity metrics or surveillanceOur goal is not to optimize for “more output,” but for better engineering.The Team You’ll Work WithYou’ll work directly with:Andrew (CTO) – previously a founding engineer at Causal, MIT alum.
