Responsibilities
- Architect, design, and develop robust, scalable, maintainable geometry capabilities for CAE products.
- Provide technical leadership for geometry modeling, defeaturing, cleanup, healing, interoperability, topology handling, and CAE preprocessing workflows.
- Lead design reviews, feasibility analysis, risk assessment, debugging, performance optimization, and architecture decisions.
- Investigate geometry defects, interoperability issues, performance bottlenecks, and customer workflow problems through resolution.
- Collaborate with product management, architecture, QA, program management, and engineering teams on customer-driven technical solutions.
- Mentor engineers on geometry algorithms, design patterns, code quality, testing strategy, and engineering practices.
- Contribute to technical roadmaps and communicate tradeoffs, risks, and implementation plans.
Requirements
- Bachelor’s or Master’s degree in Computer Science, Mechanical Engineering, Computational Geometry, Computer-Aided Design, Computer-Aided Engineering, or a related engineering discipline.
- 12+ years of software engineering experience delivering commercial or enterprise engineering software.
- Deep expertise in computational geometry, topology, CAD modeling, geometry kernels, B-rep data structures, cleanup, healing, defeaturing, and interoperability.
- Strong C++ development experience for engineering, scientific, CAD, CAE, or geometry-intensive applications.
- Experience implementing robust geometry algorithms and production-quality software components for model preparation and CAE preprocessing.
- Working knowledge of CAE workflows including model preparation, meshing handoff, solver readiness, and simulation preprocessing.
- Experience with CAD/CAE products or geometry platforms such as MSC Apex, Patran, ANSA, CATIA, SolidWorks, NX, Parasolid, ACIS, or Open Cascade.
- Experience guiding architecture and implementation decisions while balancing performance, robustness, maintainability, quality, innovation, and delivery.
- Familiarity with scripting, automation, build systems, debugging, profiling, and engineering productivity practices; Python experience is preferred.
- Experience mentoring engineers, reviewing complex designs, and influencing technical direction without direct people-management responsibility.
- Practical experience using AI-assisted development tools such as GitHub Copilot or Cursor.
- Strong understanding of geometry algorithms including intersection, projection, trimming, tolerance handling, curve and surface evaluation, spatial search, and proximity calculations.
- Hands-on experience with B-rep topology, feature recognition, geometry cleanup, healing, defeaturing, and topology repair.
- Experience with CAD data translation, interoperability, and neutral formats such as STEP, IGES, Parasolid, or ACIS.
- Ability to design geometry APIs, reusable components, and scalable data structures for complex engineering models.
- Strong debugging and diagnostic skills for geometric robustness, numerical precision, and customer workflow failures.
- Experience optimizing geometry operations for performance, memory usage, scalability, and responsiveness.
- Familiarity with automated testing for geometry algorithms, including regression tests, tolerance-based validation, stress cases, and customer model validation.
- Strong communication, collaboration, analytical, organizational, and time-management skills.
