Senior 3D & AI Systems Software Developer
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
CoLab’s AutoReview product is a core part of how we bring AI and engineering expertise together to improve design quality. So far, much of that work has focused on 2D drawings. Now, we’re building the future of 3D AutoReview — and we need a backend engineer who’s excited to help in that mission.
You’ll join the AutoReview team and help build the systems that power intelligent 3D design analysis at scale. That includes everything from geometry parsing and model analysis to backend infrastructure, rule systems, and AI-assisted review workflows. This is deeply technical, multidisciplinary work that sits at the intersection of backend engineering, CAD systems, and machine learning.
You’ll spend time experimenting, testing assumptions, and solving problems that don’t have obvious answers. You won’t be handed perfectly scoped projects or detailed specs. But you will get ownership, support, and the opportunity to shape how AI-driven design review evolves inside some of the world’s leading engineering organizations.
Our Ideal Candidate
You’ve got solid backend engineering experience, ideally with exposure to 3D CAD modelling or using tools like OpenCascade or Parasolid. You’re comfortable with math-heavy problems (linear algebra, vector calculus), and bonus points if you’ve worked in ML/LLM environments or with HOOPS.
You like to understand the “why” behind the work and communicate it clearly. You thrive in ambiguity and don’t wait for someone else to go first. If something’s unclear, you figure it out—and then explain it to the rest of the team. You’re ready to be the go-to person for 3D anomalous within the AutoReview space and help others get up to speed.
Frequently cited statistics show that people who identify with historically marginalized groups are likely to apply to jobs only if they meet 100% of the qualifications. We encourage you to help us break that statistic and apply even if you don’t meet every single qualification—your potential is what matters most to us.

Most of CoLab's open roles are remote-tagged for Canada, with several also open to the United States and broader North America. CoLab also lists two Europe-remote roles (Industry Strategy Manager and Key Account Executive) and one hybrid role based in St. John's, NL or Toronto, ON.
CoLab's careers page highlights health and dental coverage with the employer paying up to 100% of premiums, RRSP and 401(k) matching, stock options, unlimited PTO, a mental health benefit up to $1,000 per year, a home office stipend up to $1,000, and parental, maternity, or adoption top-up to 80% for 15 weeks.
CoLab raised a $72M USD Series C in November 2025, led by Intrepid Growth Partners, following a $21M Series B and a $17M Series A. That gives it a stable base for continued hiring and growth.
CoLab is hiring across engineering (Mechanical Engineer, Forward Deployed Engineer, Senior Back End Developer, Senior Full Stack Developer), sales (Key Account Executive, Director of Sales, Major Account Director), customer success (Strategic CSM, Senior Implementation Specialist), and marketing (Senior Director Growth Marketing, Senior Product Marketing Manager).
CoLab runs a CoLaborator of the Week program, announced by the CEO at the company-wide weekly meeting with a gift card, alongside quarterly performance reviews and a referral bonus of $750 to $9,000.
