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 DoAs 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
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
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
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.
