Founding Design Engineer

Weave (YC W25) is building the definitive platform for understanding and improving how engineering teams work. We believe the way engineering output is measured today is fundamentally broken and that modern AI can give teams a far more accurate and actionable view of productivity, impact and collaboration.Trusted by 200+ customers such as Robinhood, Rho, PostHog and Browserbase, we’ve delivered consistent double-digit month-over-month revenue growth since May and are looking to accelerate our growth.As Weave's Founding Design Engineer, your job is to make complex engineering data feel simple, beautiful and actionable. You'll own the intersection of design and engineering, turning insights about how software teams work into interfaces that leaders and engineers actually love using. You'll be building our design systems and frontend standards as you go to make every incremental feature easier to build and more delightful to use. Your goal will be to delight customers with experiences that make their job 10x easier.We’ve raised a $4.2M seed round and are backed by Moonfire, Burst capital and Y Combinator (W25).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.

You should be equally comfortable in Figma and in code. You're obsessed with craft, the micro-interaction that feels off, the visualization that could tell a clearer story, the flow that adds one too many clicks.You must be empathetic.
