Our mission
To build the next generation of purpose-built developer tooling to bend the curve on software quality and development velocity. We are starting with the problem of code review and quality control.
The role
As a Founding Senior Frontend engineer you’ll design new interaction primitives, write code that brings our designs to life, and build a best-in-class user experience loved by developers.
Some of the challenges of the role will be around building highly performant web frontends, even as the data and content (such as PR diffs) enters into the 10s of thousands of DOM nodes, achieving great ergonomics with keyboard shortcuts, syncing data fo realtime feedback for collaborative workflows, etc.
Our stack is React, Vite, Tailwind, Tanstack Router, Tanstack/React Query, and Zero
Our team
We are a lean team with extremely high ownership and autonomy.
Mesa is lead by two repeat founders
Oliver Gilan - co-founder of Antimetal, engineer at Microsoft and Census
Ben Warren - Ex-YC, engineer at Microsoft and Census
In addition to our team, Mesa is backed by top seed investors, including Aditya Agarwal (ex-CTO of Dropbox, early engineer at Facebook), Soleio Cuervo (ex-Head of Design at Dropbox, first designer at Facebook), Ethan Yu (Founder of Motion), and Boris Jabes (CEO & Founder of Census).
Why design The Mesa?
Not just another SaaS dashboard: Most SaaS today is copy-paste — a few dashboards, lists, and forms. Mesa is creating new primitives for understanding large code diffs, collaborating effectively, and building great software.
Be seen by the world’s greatest builders: Our early investors and users invented search, the feed and the like button. From day 1, your code will empower great builders to create the next big thing.
Build for yourself: Mesa brings together engineering, product, and design in a single collaboration layer. You will use Mesa every day to build and ship software.
You’ll be a good fit if you…
Obsess over user experience. Keyboard shortcuts, information hierarchy, visual feedback, performance. The details are hard to get right but it’s the details that determine user experience. If you’re obsessed
Understand the tech stack at a deep level. We use React, Tailwind, and Vite. You should have a deep understanding for how to optimize our component tree, improve our builds and delivery of the deployed bundle, and know the latest techniques in SSR and data syncing.
Know how to 80/20 effectively. Velocity is the result of making smart tradeoffs.
Want to grind and be recognized. Effort is the only input that is entirely in our control. We stay focused and stay late, because nothing feels better than the recognition that we’ve built something great.

We are based in San Francisco and work in-person every day from our office in South Park. We work from home on weekends.
