About CoLab
At CoLab, we help mechanical engineering teams bring life-changing products to market years sooner.
We build AI for engineers designing cars, medical devices, and jet engines. Products this complex aren't sketched and sent to production. Teams spend months on iterations, reviews, and tests, predicting how every part performs before anything is built. CoLab is where those reviews happen, and we capture the rationale behind every change. Other tools show what changed between versions. Only CoLab knows why. That's how our AI helps manufacturers like Bobcat, Triumph Motorcycles, and GE Appliances make better decisions, eliminate rework cycles, and get to market faster.
Proudly based in St. John’s, Newfoundland, CoLab started with one customer in 2018. Since then we’ve raised a $72M Series C, been named the 57th fastest growing company in North America by Deloitte (Fast 500™), signed multi-year AI partnerships with companies like Bombardier, and grown to a team of 250+.
About the Role:
Mechanical engineering teams rely on a complex ecosystem of CAD, PLM, and enterprise systems to design, review, and manufacture products. At CoLab, we're building software that fits naturally into those workflows.
As a Senior Full Stack Developer, you'll play a key role in making that possible. You'll build the integrations and platform capabilities that connect CoLab with the systems our customers use every day, helping engineering organizations review designs faster, collaborate more effectively, and make better decisions throughout the Mechanical Engineering Lifecycle.
This role is a great fit for someone who enjoys solving technically challenging integration problems. Ideally you’ve spent your career building web applications and focused within heavy integrations.
You'll work closely with Product, Design, Customer Success, and fellow engineers to translate real customer challenges into scalable software. One week you might be improving how CoLab integrates with a CAD application. The next, you could be investigating a complex customer workflow spanning PLM, ERP, and engineering data to eliminate friction for thousands of engineers.
