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