Senior 3D & AI Systems Software Developer

Role Description

CoLab’s AutoReview product is a core part of how we bring AI and engineering expertise together to improve design quality. We’re building the future of 3D AutoReview — and we need a backend engineer who’s excited to help in that mission.

• Join the AutoReview team and help build systems that power intelligent 3D design analysis at scale.
• Work on geometry parsing, model analysis, backend infrastructure, rule systems, and AI-assisted review workflows.
• Engage in deeply technical, multidisciplinary work at the intersection of backend engineering, CAD systems, and machine learning.
• Experiment, test assumptions, and solve problems that don’t have obvious answers.
• Take ownership and shape how AI-driven design review evolves inside leading engineering organizations.

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.

Requirements

• 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.

Benefits

• 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.
