About CoLab At CoLab, we help mechanical engineering teams bring life-changing products to market years sooner. CoLab is the AI platform for driving stronger engineering decisions. Every design review in CoLab builds a knowledge repository of design feedback, decisions, and lessons learned - which AI agents draw from to flag issues on future designs before they compound.

The more your team works in CoLab, the smarter it gets and the faster you arrive at the ideal design. Companies like Ford, Komatsu, and Johnson Controls use CoLab to catch issues earlier, eliminate rework cycles, and bring products to market faster. Founded in St.

John’s, Newfoundland, CoLab has grown quickly from our first customer in 2019 to a rapidly scaling company. We’ve recently been recognized on Deloitte’s Fast 50™ and Fast 500™, and named a Canadian company to watch by The Globe and Mail and Financial Post.

About The Role

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.

Our Ideal Candidate 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.
