Junior Full Stack Engineer

Who We Are

Baton Corporation is the development company that builds and operates the entire technology stack behind pump.fun, the largest memecoin launchpad in production today. Our systems are low latency, high throughput, live under constant load, and demand precision.

What You’ll Do

As a Junior 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

We are looking for an exceptional early-career engineer with a strong foundation in computer science and the ability to ramp quickly on new systems and codebases. Ideal candidates will have:

• Studied at a top university or demonstrated equivalent ability through competitive programming, Olympiads, open-source contributions, or substantial personal projects.
• Comfort working across the stack, with hands-on experience in technologies like TypeScript, React, Next.js, and Node.js (or adjacent modern frameworks).
• Curiosity and intellectual rigor – you enjoy understanding why systems work, not just how to use them.
• Strong problem-solving skills to 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.
• Motivation by fast feedback, real users, and an environment where what you ship matters immediately.
• A hunger 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, and the 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.
