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.
CoLab is seeking a Principal Developer to join our growing team.
In this high-impact, hybrid role, you will work closely with our leadership team as a senior Individual Contributor (IC) and product thinker. Your primary focus will be on supporting strategic initiatives from a technical perspective.
You will help define our product roadmap by building working prototypes, pressure-testing initial assumptions, proposing potential approaches, and transforming technical unknowns into clear, actionable product direction.
Our ideal candidate has previous experience working on browser-based 3D/2D graphics engines, and or Computer Aided Design (CAD) softwares, and a strong track record of applied R&D in a SaaS context.
You’re comfortable working without a clear path, and enjoy engaging with a broad set of stakeholders (product, design, leadership and customers) to clarify outcomes and validate potential solutions. You are high agency, and find ambiguous, open-ended challenges exciting.
If you’re looking for clear requirements and defined scopes that you can simply execute on, this likely won’t be the right fit.
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.

CoLab is a cloud based platform for engineering design review. We make it easy for subject matter experts (SMEs) across your business to access, evaluate, and comment on 2D drawings and 3D models. Our built-in AI peer checker, AutoReview, can analyze designs for you and spot common errors or non-compliance with your standards and guidelines. AutoReview creates markups and comments on your files, in context – just like a human checker.
With CoLab, human SMEs and AI work together to help you make better decisions and improve designs faster. We automatically capture knowledge from across your global business that would otherwise be buried in emails, spreadsheets, slide decks, and unknown locations in Sharepoint or PLM. Then, we make sure every lesson learned and every design guideline is applied exactly when it matters.
Companies like Johnson Controls, Komatsu, Schaeffler, and Polaris have launched products 40% faster, cut BOM costs by 50%, and reduced quality escapes by 15% in 1 year.
