About the role
What you’ll do
- Own CAD process reliability: manage SolidWorks instances running as headless multi-process services. Debug RPC errors, COM failures, and process hangs. Build robust process pool management with health checks, kill-and-restart, and graceful degradation.
- CAD API development: extend our SolidWorks automation layer (step export, JSON export, drawing generation). Expand to Creo (C++ toolkit), and eventually other CAD platforms. Build a common abstraction layer across CAD engines.
- File format handling: debug and fix GLB/GLTF export issues, step file conversion across CAD versions (2017–2025), surface body detection, geometry validation. Handle edge cases from files exported by different CAD systems (CATIA, Creo, Fusion, NX).
- 3D viewer reliability: work on face selection accuracy, bounding box calculations, rendering performance for our web-based 3D viewer (Three.js). Fix zoom-dependent selection issues, normal direction bugs, and ray casting edge cases.
- Multi-CAD expansion: architect the integration layer for new CAD platforms. Creo requires C++ (no C# option). Design how C# and C++ layers interact, how common data models work across CAD engines.
- Version compatibility: ensure our pipeline works across SolidWorks versions (2017–2025), handle API differences, detect file versions correctly, and maintain backward compatibility.
Must have
- 3–8 years of CAD software customization or development. Not CAD usage, CAD API programming.
- C++ and C# in production. COM interop experience. Comfortable debugging at the process/memory level on Windows.
- SolidWorks API, Creo Toolkit, NX Open, CATIA CAA, or similar CAD APIs. At least one deeply, others as exposure.
- Understands why CAD apps crash when you try to multithread them, and has built workarounds.
- Step file format, B-Rep geometry, solid vs surface bodies, feature recognition basics.
- Comfortable with Windows development , process management, services, COM objects, RPC debugging.
- Uses AI tools daily (Cursor, Copilot, Claude) to navigate unfamiliar API docs, debug issues, and iterate fast. CAD APIs are poorly documented , you need to be resourceful.
