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.

As a Full Stack Engineer at Baton, you’ll work on production systems operating at real scale, alongside a team of highly experienced engineers. This is a hands‑on role with immediate responsibility and fast feedback.

• Build, ship, and iterate on production features that reach hundreds of thousands of users
• Work across the stack, from backend services and data pipelines to frontend interfaces, gaining deep exposure to how large systems are built and operated
• Learn to design for performance, reliability, and scalability by working on systems under real‑world load
• Prototype quickly, test ideas with real users, and refine based on data rather than opinion
• Tackle ambiguous, technically challenging problems and learn to reason from first principles with guidance from experienced engineers
• Collaborate closely with a small, high‑caliber team where code quality, clarity of thought, and execution speed matter
• Own features end to end, from initial idea and implementation through deployment, monitoring, and iteration

• An exceptional early‑career engineer with a strong foundation in computer science and the ability to ramp quickly on new systems and codebases
• Studied at a top university or demonstrated equivalent ability through competitive programming, Olympiads, open‑source contributions, or substantial personal projects
• Comfortable working across the stack, with hands‑on experience in technologies like Type Script, React, Next.js, and Node.js (or adjacent modern frameworks)
• Curious and intellectually rigorous — you enjoy understanding why systems work, not just how to use them
• A strong problem solver who can break down ambiguous problems, reason from first principles, and iterate toward solid solutions
• High‑agency and ownership‑oriented, eager to take responsibility for features end to end while learning from more experienced engineers
• Motivated by fast feedback, real users, and an environment where what you ship matters immediately
• Hungry to learn from exceptional peers and grow rapidly by working on challenging problems at real scale

• 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

• 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.
