Job description
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. The systems are low latency, high throughput, live under constant load, and break if you get them wrong.
What You’ll Do
As a Senior Staff Full Stack Engineer, you’ll remain deeply hands‑on while shaping the technical direction of our platform across frontend and backend systems. You’ll own the hardest cross‑stack problems - performance, scalability, correctness, and architectural coherence in a fast‑moving environment.
Architect and build high‑performance systems across the entire stack, directly contributing production code in both frontend and backend layers.
Define and evolve cross‑stack architecture that scales with user growth, product complexity, and real‑time interaction demands.
Lead complex, multi‑surface initiatives end to end— from system design and RFC through implementation, rollout, and iteration.
Design clean boundaries between frontend, backend, and blockchain infrastructure, ensuring systems remain modular and adaptable as we scale.
Anticipate systemic bottlenecks (performance, data consistency, infra limits) and proactively design durable solutions.
Drive improvements in performance, reliability, and observability across the stack.
Rapidly prototype and validate new product ideas while ensuring that successful experiments evolve into production‑grade systems.
Raise the bar for engineering quality through design reviews, architectural guidance, and hands‑on mentorship.
Act as a technical anchor during critical launches, migrations, or incidents that span multiple parts of the stack.
Improve developer velocity by evolving tooling, CI/CD pipelines, testing strategy, and shared abstractions.
Who You Are
Proven track record of owning large cross‑stack systems serving real users under real load.
Deep expertise in TypeScript, React, Next.js, and Node.js (or equivalent backend frameworks), with strong architectural instincts.
Comfortable reasoning about distributed systems, data modelling, caching, and client–server tradeoffs.
Able to move fluidly between frontend performance optimisation and backend system design.
Known for solving ambiguous, cross‑cutting technical problems that span multiple layers of the stack.
High‑agency and execution‑driven— you influence direction by building and shipping.
Comfortable setting technical direction without stepping away from implementation.
Experience in high‑growth or high‑scale environments where systems must evolve rapidly without collapsing under complexity.
Familiar with crypto, DeFi, or blockchain systems—especially real‑time interactions, indexing, or wallet‑integrated applications.
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.
