From the employer
Who We Are
Baton Corporation is the development company that builds and operates the entire technology stack behind pump.fun, the largest memecoin launchpad in production today. The systems are low latency, high throughput, live under constant load, and break if you get them wrong.
What You’ll Do
As a Staff Frontend Engineer, you’ll own the design and evolution of large parts of our frontend architecture. This is a hands-on, high-impact role focused on building fast, reliable, and maintainable user-facing systems under real load.
Architect and evolve large-scale frontend systems using React and Next.js that serve hundreds of thousands of users
Own performance, reliability, and correctness across critical user flows, including rendering performance, state management, and data fetching
Design frontend abstractions and patterns that scale with team and product complexity, not just feature count
Work closely with backend and Solana engineers to define clean, efficient client–server boundaries
Lead complex frontend initiatives end to end, from technical design through implementation, rollout, and iteration
Set a high bar for code quality, testing, and operational readiness across the frontend codebase
Mentor and unblock other frontend engineers through design reviews, pairing, and hands-on guidance
Who You Are
A staff-level frontend engineer with deep experience building production React applications at scale
Have owned frontend systems used by large, real user bases, not just internal tools or small apps
Strong understanding of browser internals, rendering pipelines, performance optimisation, and modern frontend tooling
Comfortable designing systems that balance developer velocity, performance, and long-term maintainability
Deep experience with React, Next.js, and TypeScript; comfortable working close to the metal when needed
High-agency and ownership-driven, able to drive large initiatives with minimal guidance
Thoughtful about tradeoffs and able to make pragmatic decisions based on real-world constraints
Interested in crypto systems or high-scale consumer products, and excited by fast-moving environments
What it's like to work here
We work in person
Hours can be long and unconventional
The pace is intense
Expectations are high, and impact is immediate
Working at Baton is not for everyone
Why Join Us?
Unmatched ownership and autonomy
Exposure to systems operating at the edge of crypto scale
The ability to ship fast and see real-world impact immediately
If you’re motivated by responsibility, speed, and building products used by massive audiences, you’ll feel at home here.
