Senior Staff Full Stack Engineer ($500k - $1.5m salary)
Baton · New York City
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
