Staff Frontend Engineer

Who We Are

Bags.fm is the development company that builds and operates the entire technology stack behind bags.fm , the leading launchpad for new projects and ideas. The systems are low latency, high throughput, live under constant load, and break if you get them wrong.

  What You’ll Do

As a Staff Frontend Engineer, you’ll own the design and evolution of large parts of our frontend architecture. This is a hands-on, high-impact role focused on building fast, reliable, and maintainable user-facing systems under real load.

• Architect and evolve large-scale frontend systems using React and Next.js that serve hundreds of thousands of users

• Own performance, reliability, and correctness across critical user flows, including rendering performance, state management, and data fetching

• Design frontend abstractions and patterns that scale with team and product complexity, not just feature count

• Work closely with backend and Solana engineers to define clean, efficient client–server boundaries

• Lead complex frontend initiatives end to end, from technical design through implementation, rollout, and iteration

• Set a high bar for code quality, testing, and operational readiness across the frontend codebase

• Mentor and unblock other frontend engineers through design reviews, pairing, and hands-on guidance

  Who You Are

• A staff-level frontend engineer with deep experience building production React applications at scale

• Have owned frontend systems used by large, real user bases, not just internal tools or small apps

• Strong understanding of browser internals, rendering pipelines, performance optimisation, and modern frontend tooling

• Comfortable designing systems that balance developer velocity, performance, and long-term maintainability

• Deep experience with React, Next.js, and TypeScript; comfortable working close to the metal when needed

• High-agency and ownership-driven, able to drive large initiatives with minimal guidance

• Thoughtful about tradeoffs and able to make pragmatic decisions based on real-world constraints

• Interested in crypto systems or high-scale consumer products, and excited by 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 Bags.fm 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.
