Senior Surface Geometry Algorithm Expert

Senior Surface Geometry Algorithm Expert

Responsibilities:
Design and implement advanced surface construction algorithms using geometric and topological constraints, enabling parametric modeling workflows for industrial applications (e.g., industrial design, CAE).
Develop and optimize surface deformation algorithms, including freeform deformation (FFD), feature-preserving modifications, and constraint-based editing techniques.
Integrate robust, precise, and scalable surface algorithms into commercial-grade CAD geometry kernels (e.g., OpenCASCADE, Parasolid, ACIS, or proprietary kernels).
Conduct mathematical modeling and numerical analysis to ensure algorithm convergence, stability, and high performance in production environments.
Develop and maintain production-grade, well-documented C++ code with comprehensive unit testing.
Research and integrate state-of-the-art computational geometry techniques into the product roadmap.

Requirements

Master's or PhD in Computer Science, Applied Mathematics, Mechanical Engineering, or a closely related field.
5+ years of hands-on experience in developing computational geometry algorithms or CAD geometry kernels.
Expert proficiency in modern C++ (C++11/14/17).
Deep theoretical and practical knowledge of Computational Geometry and Numerical Optimization, including:

• Bézier, B-Spline, and NURBS curve/surface theory.
• Expertise in Newton-Raphson methods, Least Squares optimization, and related numerical solvers.
• Proven experience integrating algorithms into commercial-grade CAD geometry kernels (e.g., OpenCASCADE, Parasolid, CGM, ACIS, or equivalent proprietary systems).

Preferred Qualifications

Experience in freeform surface modeling and real-time surface editing.
Development experience with constraint-based surface construction and surface deformation algorithms.
Understanding of BRep (Boundary Representation) data structures and Topological Naming mechanisms.
Contributions to open-source CAD or computational geometry projects (e.g., OpenCASCADE, FreeCAD, CGAL).
Experience with parallel computing (e.g., multi-threading, GPU acceleration) for geometric algorithms.
