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 Engage 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. 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. Success Will Be Measured By: - On-time delivery of user-facing features and enhancements - Code that’s scalable, accessible, and easy to maintain - Clear communication and collaboration across teams - Proactive ownership of tasks and awareness of broader technical context - Contributions to front-end best practices and continuous improvement Job Responsibilities - Build and maintain UI features using React, TypeScript, and our internal component library - Work with product and design to translate user needs into front-end solutions - Develop, test, and ship changes regularly as part of sprint-based releases - Participate in code reviews and contribute to front-end architecture decisions - Advocate for performance, accessibility, and usability across the platform - Collaborate with back-end and infrastructure teams to integrate APIs and optimize workflows - Help maintain and improve our testing practices using tools like Cypress or Playwright - Share your knowledge and learn from others — mentorship is a two-way street Qualifications Required: - 5+ years of professional front-end development experience - Strong proficiency with React, TypeScript, HTML, and CSS - Experience integrating APIs and working within a modern front-end toolchain (e.g. Vite, Webpack, npm, ESLint) - Familiarity with Git workflow (pull requests, branches, code reviews) - Experience writing automated tests (unit, integration, and E2E) - Understanding of front-end performance principles and accessibility best practices - Strong communication skills and a collaborative mindset Nice-to-Have: - Experience with design systems and scalable component libraries - Familiarity with GraphQL - Familiarity with Python - Experience working closely with product designers Extra Details - Compensation: This is a full-time, permanent position with an attractive compensation package that includes a stock options package. - Benefits: This role offers an extended health and benefits package that includes unlimited paid vacation and RRSP matching. - Remote/Hybrid Work: Our main office is located in St. John’s, NL, where we offer hybrid and remote opportunities.
