CAD Integration Software Engineer

Job summary

Job Description OVERVIEW Boy***'s CFD team is seeking a dynamic software engineer to lead the integration of a commercial 3D geometry modeling kernel (Parasolid or equivalent) into our thermal simulation software. This role is central to modernizing our CAD processing capabilities and will directly impact product quality for engineers across North America.

Qualifications

• 3–5 years professional experience with a B-rep geometry kernel such as Parasolid, ACIS, or OpenCASCADE
• Bachelor's degree in Computer Science, Software Engineering, or related engineering field with strong programming foundation
• Have the ability to work within a group and have strong leadership
• Experience migrating between geometry kernels or integrating multiple CAD libraries
• Python proficiency for integration work, scripting, and API development
• C++ or C#/Python interop experience
• Knowledge of mesh generation algorithms and techniques
• Background in numerical methods or computational modeling
• Prior work in thermal analysis or CFD simulation environments
• WORKING ENVIRONMENT
• Join a small, collaborative development team working on a mature, commercially deployed simulation product.
• This role offers significant autonomy in technical decision-making and implementation approach.

Responsibilities

• Architect and implement integration between a commercial geometry kernel and existing CFD/thermal simulation software, replacing current OpenCASCADE-based workflows
• Develop Python integration layers connecting the geometry kernel to CFD solvers and C++ numerical modules
• Design APIs for CAD import, geometry healing, and model simplification workflows
• Write clean, maintainable code following established architectural patterns and participate in code reviews
• Debug and optimize performance for complex geometric operations on large assemblies
• Create technical documentation and contribute to user-facing help content
• Required
