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, 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
