Senior 3D & AI Systems Software Developer

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 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. 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 modeling 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. Job Responsibilities Become a key contributor in the backend development for 3D AutoReview features, from pipeline architecture to production delivery Experiment with geometry parsing, quality detection, and context generation for 3D model review Partner with backend, frontend, and product teams to drive the delivery of high-impact features with speed, quality, and cross-functional alignment. Collaborate with ML teams to incorporate intelligence into the 3D review process Develop extensible systems for custom rule creation and reference data in 3D AutoReview Help set and maintain high technical standards across the team Qualifications 5+ years of experience in backend development, ideally in a product or platform team Solid grasp of 3D math with practical experience in graphics engines, CAD kernels (HOOPS, OpenCascade, Parasolid), Robotics, 3D simulations, etc. Hands-on experience designing, developing, and maintaining robust, scalable backend systems and APIs Experience working with multiple data storage paradigms (SQL, NoSQL, and vector databases) Experience with ML/AI/LLM concepts and productionalization Familiarity with 3D model ML pipelines (e.g., feature extraction, embedding generation, model training, or inference) Familiarity with agentic workflows (e.g., pydantic-ai) Experience integrating and prompting large language models (LLMs) via APIs (e.g., OpenAI, Anthropic, Google Gemini) Knowledge of ML frameworks such as PyTorch, Hugging Face, or Scikit-learn Experience deploying ML services in cloud infrastructure (e.g., AWS SageMaker, Amazon Bedrock, etc.) Comfortable working with ambiguous or loosely scoped technical challenges Excellent communicator—able to translate technical problems into clear paths forward Experience with CAD modeling software like SolidWorks, Creo, or OnShape is a strong plus Experience with mechanical engineering concepts is a strong plus Extra Details This is a full-time, permanent position with a competitive compensation package that includes stock options Includes extended health benefits, unlimited paid vacation, and RRSP/401K matching and 100% health/dental coverage Fully remote within North America 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. 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.
