Responsibilities
- Architect, design, and develop advanced geometry capabilities for CAE products.
- Lead technical work involving geometry modeling, defeaturing, cleanup, healing, interoperability, topology handling, and CAE preprocessing.
- Provide technical authority for design reviews, feasibility analysis, risk assessment, debugging, performance optimization, and architecture decisions.
- 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.
- Investigate geometry defects, interoperability issues, performance bottlenecks, and customer workflow problems through resolution.
- Contribute to technical roadmaps and communicate design tradeoffs, risks, and implementation plans.
- Optimize geometry operations for performance, memory usage, scalability, and responsiveness in large assemblies and complex CAE models.
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.
- 13+ years of software engineering experience delivering commercial or enterprise engineering software, preferably in CAD, CAE, geometry, or simulation domains.
- Deep expertise in computational geometry, topology, CAD modeling concepts, geometry kernels, B-rep data structures, cleanup, healing, defeaturing, and interoperability workflows.
- Strong C++ development experience for large-scale engineering, scientific, CAD, CAE, or geometry-intensive applications.
- Experience implementing robust geometry algorithms and production-quality software for model preparation and CAE preprocessing.
- Working knowledge of CAE workflows including model preparation, meshing handoff, solver readiness, simulation preprocessing, and usability requirements.
- Experience with CAD/CAE products or geometry platforms such as MSC Apex, Patran, ANSA, CATIA, SolidWorks, NX, Parasolid, ACIS, or Open Cascade.
- Experience designing geometry APIs, reusable software components, scalable data structures, and geometry algorithms involving intersection, projection, trimming, tolerance handling, curve and surface evaluation, spatial search, and proximity calculations.
- Experience with CAD data translation, interoperability, and neutral formats such as STEP, IGES, Parasolid, and ACIS.
- Strong debugging and diagnostic skills for geometric robustness, numerical precision, and customer workflow issues.
- Familiarity with scripting, automation, build systems, debugging tools, profiling tools, and automated testing strategies for geometry algorithms.
- Working knowledge of Python or scripting tools for automation, diagnostics, workflow prototyping, and engineering productivity.
- Experience mentoring engineers, reviewing complex designs, and influencing technical direction without direct people-management responsibility.
