About this role
## Baton Corporation — Senior Staff Full Stack Engineer ### 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. Our 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, contributing production code in both frontend and backend - 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 (system design → RFC → implementation → rollout → iteration) - Design clean boundaries between frontend, backend, and blockchain infrastructure to keep systems 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, ensuring 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 spanning 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 modeling, caching, and client-server tradeoffs - Able to move fluidly between frontend performance optimization and backend system design - Known for solving ambiguous, cross-cutting technical problems across 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.
