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 Growth Engineer, your job is to make sure every engineer who hears about Weave ends up using it. You'll own the self-serve funnel end to end, from the first visit to the website to the moment a team is hooked, and you'll build the systems that turn that funnel into pipeline for sales.
We've raised a $13.5 million Series A and are backed by Standard Capital, YCombinator, Moonfire, Burst Capital, IrregEx and the Agent Fund.
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 BUILDING
Weave 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 impact
- Help teams improve outcomes without vanity metrics or surveillance
Our goal is not to optimize for "more output," but for better engineering.
THE TEAM YOU'LL WORK WITH
You'll work directly with:
- Andrew (CTO) – previously a founding engineer at Causal, MIT alum. Andrew has been in your shoes and is deeply committed to providing the mentorship, ownership and growth he had as an early engineer.
- Adam (CEO) – leads sales and customer discovery. Adam is a former sales executive at multiple high-growth startups and deeply embedded with customers and scaled multiple sales teams from $0-30M in ARR.
This is a small, intense, highly collaborative team. You will have real ownership from day one.
THE ROLE
This isn't a traditional growth role and we're not looking for a growth operator who can write a little SQL. The closest thing we can describe it as is a mashup of full-stack engineer, growth PM, data analyst and marketer.
Today Weave grows because the product is good and the sales team is relentless. Engineers hear about us, install Weave or the Weave Router, and tell their teams. Your job is to turn that into a machine: a website that converts, a signup that takes minutes, onboarding that gets a team to their first real insight fast, and the data to know which of those teams sales should call today.
You'll sit on the GTM team, write production code every week and be measured on one thing: how many engineering teams start using Weave and stick. Not on assisting someone else's strategy, not on optimizing a slice of a funnel, but on the whole funnel, end to end. If you've been waiting for the role where you actually get the keys, this is it.
RESPONSIBILITIES
- Own the funnel end to end. Website, signup, onboarding, activation, expansion. You decide what to fix first, you fix it and you report on whether the number moved.
- Build the website like a product. Landing pages, pricing, programmatic SEO pages, interactive demos, the docs entry points. Ship, measure, iterate. No waiting on an agency.
- Make onboarding take minutes. Own the signup and first-run experience for Weave and the Weave Router: connecting a repo, installing the router, getting to the first insight a team actually cares about. Find where people drop off and fix it in the product code.
- Run the experimentation engine. Build the A/B testing, feature-flag and event-tracking infrastructure, then use it. Real hypotheses, clean experiments, honest readouts. Kill what doesn't work, double down on what does.
- Build the growth data stack. Attribution, product-qualified lead scoring, CRM sync. Sales should know which self-serve teams are ready for a conversation before…
