About the Company

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.

• 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

Requirements

• Highly experienced engineer who has deployed production smart contracts or on-chain programs at scale
• Experience dealing with performance bottlenecks, edge cases, and real-world failure modes
• Deep understanding of security, adversarial environments, and long-term maintainability
• Ability to work independently and make sound technical decisions with incomplete information
• Motivation for operating real systems at scale
