WHY BOX NEEDS YOU
Every file uploaded, every download clicked, every task completed — our engineering team builds the core experiences that make it all happen. We're evolving our React architecture into a faster, more reliable, and delightful experience — built for an AI-driven world — while shipping new features customers are actively asking for. If you're excited by building at scale, partnering closely with Product and Design, and leading complex architectural evolution with zero downtime, this role is for you.
As a Senior Software Engineer focused on frontend, you'll drive end-to-end delivery of high-impact features, contribute to our next-generation architecture and design blueprints, and help overhaul our processes to improve quality and velocity. You'll work on a team that actively embraces AI-assisted tooling and workflows while staying grounded in strong engineering fundamentals — writing clean code, making thoughtful design decisions, and building systems that last. You'll also take part in releases and on-call rotations to keep our core workflows available and performant.
