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

WHO WE ARE Baton Corporation is the development company that builds and operates the entire technology stack behind pump.fun http://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 Frontend Engineer, you’ll remain deeply hands-on while shaping the technical direction of our frontend platform. You’ll own the hardest frontend problems - performance under real load, architectural scalability, and correctness in complex, stateful systems. - Architect and evolve large-scale frontend systems using React and Next.js that serve hundreds of thousands (and eventually millions) of users - Define and drive long-term frontend architecture strategy while actively implementing critical parts of the system -

• Own performance, reliability, and correctness across mission-critical user flows, including rendering performance, state management, caching, and data synchronization -
• Lead the design of frontend systems that handle real-time updates, blockchain state changes, and high-frequency interactions without degrading UX -
• Establish scalable patterns and abstractions that enable rapid product iteration without increasing systemic complexity -
• Drive cross-functional architectural decisions with backend and Solana engineers, shaping clean client–server boundaries and data contracts - Anticipate scaling bottlenecks and proactively redesign systems before they become constraints -
• Lead multi-quarter frontend initiatives end to end - from RFC and design to rollout, monitoring, and iteration - Raise the bar for engineering quality through rigorous design reviews, performance audits, testing standards, and operational readiness -
• Improve developer velocity by evolving tooling, build systems, CI/CD, observability, and frontend infrastructure - Act as a technical anchor during high-pressure launches or incidents affecting core user flows WHO YOU ARE - Have repeatedly built and evolved large-scale production React systems serving real users under real load -
• Deep understanding of browser internals, rendering pipelines, hydration, streaming, and performance profiling -
• Strong architectural instincts - able to design frontend systems that remain coherent as product and team scale - Expert in React, Next.js, and TypeScript, with fluency in state management strategies, caching models, and data-fetching tradeoffs -
• Comfortable reasoning about distributed systems from the client side - including consistency, latency, and eventual state alignment - Known for solving ambiguous, cross-cutting frontend problems others struggle with - High-agency and execution-focused - you shape direction by building, not by delegating. - Able to influence technical decisions across teams through clarity of thinking and strength of implementation - Excited by high-scale consumer systems, crypto-integrated products, and fast-moving environments 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.
