About this role
Who We AreBaton 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 DoYou’ll design, build, and maintain on-chain programs that operate under heavy real-world load. This is a hands-on role with real ownership and immediate impact.
Design and implement high-performance Solana programs in Rust that handle significant transaction volume
Reason carefully about program correctness, security, and upgradeability in a production environment
Optimise compute usage, account layouts, and transaction flows for latency and throughput
Work closely with backend and frontend engineers to design clean on-chain / off-chain boundaries
Debug, test, and ship changes that go live quickly and are used by hundreds of thousands of users
Participate in design discussions around protocol changes, economic mechanics, and system constraints
Own programs end to end: from design and implementation through deployment, monitoring, and iteration
Who You AreHighly experienced engineer who has deployed production smart contracts or on-chain programs that operate at meaningful scale, with real users, sustained volume, and operational constraints
Understand that building at scale is different from deploying isolated contracts - you’ve dealt with performance bottlenecks, edge cases, and real-world failure modes
Thoughtful about security, adversarial environments, and long-term maintainability
Able to work independently, take ownership, and make sound technical decisions with incomplete information
Motivated by operating real systems at scale
What it's like to work hereWe 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.
