Who we are About Stripe Stripe is a financial infrastructure platform for businesses. Millions of companies - from the world’s largest enterprises to the most ambitious startups - use Stripe to accept payments, grow their revenue, and accelerate new business opportunities. Our mission is to increase the GDP of the internet, and we have a staggering amount of work ahead. That means you have an unprecedented opportunity to put the global economy within everyone's reach while doing the most important work of your career. About the Organization The JavaScript Infrastructure Engineering team is a high impact, high leverage, and high visibility team that supports the productivity of Stripe’s frontend engineers. The team creates and supports cross cutting infrastructural libraries, services, and utilities; establishes and enforces clean coding patterns; makes sweeping code changes that improve the quality of code at Stripe; and improves build times and reliability. That’s not easy. We work with a code base of several million lines of code (and counting), used by thousands of engineers across the globe and we must focus at many levels of the stack. It's rewarding and what we do is key to allowing Stripe engineers working in our products to have the most productive time of their careers. What you’ll do We're looking for engineers who are excited about making large-scale frontend development fast, reliable, and maintainable. You'll own parts of the infrastructure that every Stripe UI engineer depends on, from remote devboxes to CI, and build solutions where open-source tooling doesn't scale to our needs. Responsibilities • Build and maintain Stripe's frontend package manager, build toolchain, bundler setup, and TypeScript infrastructure • Lay the groundwork for AI-native frontend development • Drive consistency and best practices across Stripe's JS codebases through tooling • Own SLOs for build performance, install speed, and developer tooling reliability • Debug and resolve developer-facing incidents during on-call, providing timely support to UI engineers across Stripe • Partner with frontend product and platform teams to understand friction points and continuously improve the core edit/build/test loop Who you are We're looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply. The preferred qualifications are a bonus, not a requirement. Minimum requirements • 2+ years of software development experience, with a strong foundation in JavaScript or TypeScript • Knows their way around the modern frontend ecosystem, and has worked on complex web applications with a global user base • Deep systems thinking: you consider edge cases, failure modes, and downstream effects when designing solutions • Motivated by improving the experience of the engineers around you; you measure your success by their productivity and happiness • Comfortable working with high autonomy on problems where the right solution isn't obvious • Strong written communicator, able to share context and decisions clearly across a distributed team Preferred Qualifications • Experience building or contributing to developer tooling, CLI tools, or build infrastructure • A background building frontend products with React is helpful, but we're especially interested in candidates eager to improve how frontend developers work, wherever that takes them in the stack.
