About The Position

As a Front-End Developer (Software Developer IV) on our Build Auto Review team, you’ll bring modern, user-focused front-end skills to an evolving platform used by global engineering teams. You’ll work with designers, product managers, and back-end developers to build responsive, performant, and accessible UI experiences, helping CoLab users engage with complex data and workflows in simple, intuitive ways. This is a senior role, ideal for someone who has real production experience in React and TypeScript, is confident in navigating a modern front-end codebase, and is looking to grow through collaboration, ownership, and impact. You’ve worked in a front-end role at a SaaS company or on a product team, and you’re comfortable shipping features with real users and real deadlines. You write clean, maintainable code and enjoy working closely with design and product to bring thoughtful interactions to life. Experience working on high-usage interfaces or data-rich applications is an asset. This role requires both technical confidence and curiosity — someone who wants to build an excellent UI, but is also motivated by learning how users work and how to make their experience better.
