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.
