Responsibilities
- Design and develop advanced geometry capabilities for CAE products with emphasis on robustness, performance, scalability, and maintainability.
- Lead feature-level technical work involving geometry modeling, defeaturing, cleanup, healing, interoperability, topology handling, and CAE preprocessing.
- Develop robust geometry algorithms, APIs, reusable components, and data structures for complex engineering models.
- Perform design reviews, feasibility analysis, risk assessment, debugging, profiling, performance optimization, and implementation planning.
- Investigate geometry defects, interoperability issues, performance bottlenecks, numerical precision problems, and customer workflow failures.
- Collaborate with architecture, QA, product management, program management, and engineering teams to translate customer needs into technical solutions.
- Mentor engineers on geometry algorithms, design patterns, code quality, testing strategy, and engineering practices.
- Communicate design tradeoffs, delivery risks, and implementation status to stakeholders.
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.
- 10+ years of software engineering experience delivering commercial or enterprise engineering software, preferably in CAD, CAE, geometry, or simulation domains.
- Strong 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 production-quality geometry algorithms for model preparation and CAE preprocessing workflows.
- Working knowledge of CAE workflows including model preparation, meshing handoff, solver readiness, simulation preprocessing, and customer 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 leading feature design and implementation decisions while balancing quality, performance, robustness, maintainability, and delivery commitments.
- Familiarity with scripting, automation, build systems, debugging tools, profiling tools, and engineering productivity practices; Python experience is preferred.
- Experience mentoring engineers, reviewing designs and code, and coordinating technical work without direct people-management responsibility.
- Understanding of computational 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, topology repair, CAD data translation, interoperability, and neutral geometry formats.
- Experience improving geometry operations for performance, memory usage, scalability, and responsiveness in large assemblies and complex CAE models.
- Familiarity with automated testing strategies including regression tests, tolerance-based validation, stress cases, and customer model validation.
- Strong communication, collaboration, problem-solving, analytical, organizational, and time-management skills.
