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

• 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 TypeScript, 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

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.
