Senior Cloud Architect

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.
