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.
This role sits on our Build Eng Reviews team — the group responsible for the structure and organization of CoLab’s core assets.
You’ll work on the foundational framework and layout design of CoLab’s core assets. This includes building our file drive capabilities, managing and displaying complex hierarchical data, like Assembly Structures and BOMs, and exploring new forms of engineering data such as Simulations and ECAD.
This is a front-end heavy full stack role. You’ll spend a lot of your time in the UI layer, building fast, intuitive experiences on top of complex and varied data models. But you won’t be isolated from backend or infrastructure decisions — you’ll contribute across the stack when needed.
The challenge? Visibility and urgency.
Engineers rely on these features daily. Sales relies on them in enterprise deals. Leadership has opinions. Customers have requests. Priorities can shift. You’ll need to build with focus and resilience, even when the spotlight is on.
If you like building technically demanding interfaces where performance, precision, and usability all matter — you’ll thrive here.
Our Ideal CandidateYou enjoy hard technical problems — especially the kind where rendering performance, complex data relationships, and UX intersect.
You can:
- Build elegant front-end systems on top of complex data
- Navigate shifting priorities without losing momentum
- Hold strong opinions loosely and engage in thoughtful technical debate
This team works closely with Product and other engineering teams. You won’t find someone micromanaging you — but you will find high standards and clear expectations.
Job Responsibilities- Own front-end architecture and implementation for asset organization and interaction
- Contribute to technical decisions that shape the future of CoLab’s core asset management
- Improve performance and reliability of large file rendering workflows
- Build and iterate on the UX representations of Assembly Structure and BOM data trees
- Develop new engineering review capabilities within CoLab (e.g., simulations, ECAD)
- Respond to high-impact feature requests with pragmatic, well-structured solutions
- 5+ years of experience in full stack development, with strong front-end focus
- Deep experience with modern front-end frameworks (e.g., React)
- Strong understanding of rendering performance, state management, and complex UI systems
- Experience designing, implementing, and maintaining complex relational data models
- Experience collaborating in cross-functional product teams
Bonus:
- Experience with CAD file formats or engineering software
- Experience optimizing high-performance browser applications
- Full-time, permanent position with competitive compensation and stock options
- Extended health and benefits package including unlimited paid vacation and RRSP matching (Canada)
