Junior Full Stack Engineer ($250k - $300k salary)

WHO WE ARE Baton Corporation is the development company that builds and operates the entire technology stack behind pump.fun http://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 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 WHO YOU ARE

• 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 WHAT IT'S LIKE TO WORK HERE
