Principal CAD Developer, St. John's

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 builds a knowledge repository of design feedback, decisions, and lessons learned—AI agents then 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 were recently recognized on Deloitte’s Fast 50™ and Fast 500™, and named a Canadian company to watch by The Globe and Mail and Financial Post.

About the Role 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 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 Our ideal candidate has previous experience working on browser‑based 3D/2D graphics engines, or Computer Aided Design (CAD) software, 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.

Job Responsibilities

Architect and prototype systems for ingesting and visualizing a variety of engineering data

Explore and de‑risk strategic projects through rapid experimentation

Translate deep domain knowledge into product direction and technical architecture

Work directly with design, product leadership, and customers to validate concepts

Identify constraints and opportunities in handling various design data

Qualifications

Proven track record as a staff or principal‑level developer in a SaaS environment

Experience building or shaping new products or product areas, not just implementing features

Strong ability to operate in ambiguity and define problems ahead of solving them

Extra Details

Full‑time, permanent role with competitive compensation and stock options

Remote‑first across North America

Extended health benefits, unlimited vacation, and RRSP/401K matching

Equity Note 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.
