# Senior Staff Full Stack Engineer \($500k - $1\.5m salary\) - Company: [Batoncorporation]() - Location: New York - Team: Engineering - Employment type: Full Time - Salary: $500K – $1500K - Posted: February 12, 2026 ## Job description # 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 # 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. ## Apply [Apply on Batoncorporation]() Canonical job page:
