Senior Staff Full Stack Engineer ($500k - $1.5m salary)

About the role

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.

Responsibilities

• 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

Requirements

• 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.
