Geometric Modelling Expert - CAD Kernel Development

We are urgently seeking a team of Geometric Modelling Experts to join our clients core geometry team focused on the development and enhancement of an exciting new AI based 3D CAD kernel.

You will play a key role in designing, implementing, and optimizing advanced algorithms for solid and surface modeling, with a focus on Boundary Representation (BRep), topological data structures, and precision geometry operations.

This position is ideal for someone passionate about computational geometry, CAD kernel development, and building robust, high-performance modelling tools used in engineering, manufacturing, and design applications.

There are various roles available within this team, from Engineering Management to Algorithm Development!

Salary: flexible depending on experience.

Key Responsibilities:

• Design and implement core 3D geometric modelling algorithms, including:
• Solid modelling (BRep)
• Boolean operations (union, intersection, difference)
• Surface-surface intersections
• Face/edge/vertex topology management
• NURBS and parametric surface handling
• Develop and maintain robust topological and geometric data structures.
• Collaborate with teams on geometry healing, tessellation, and mesh-BRep conversion.
• Improve algorithmic performance, robustness, and numerical accuracy.
• Debug complex geometric failures and provide analytical fixes.
• Document core algorithms and provide technical guidance to other developers.
• Contribute to test infrastructure and regression analysis for geometric operations.

Required Qualifications:

• M.S. or Ph.D. in Computer Science, Mechanical Engineering, Mathematics, or a related field.
• 10+ years of experience in developing the underlying algorithms for 3D CAD Geometry Kernels.
• Deep understanding of Boundary Representation (BRep) and geometric/topological modelling.
• Strong experience with one or more geometry kernels (e.g., Open CASCADE, Parasolid, ACIS, CGAL).
• Proficiency in C++ (and optionally Python or other scripting languages).
• Solid knowledge of differential geometry, numerical methods, and computational geometry.
• Experience developing complex 3D algorithms for industrial or academic applications.
• Must be based in Europe.
