• API/SDK development, especially CAD APIs, plugins, add‑ins, integrations, and engineering workflow automation

• Windows application installation, packaging, versioning, and updates
• API/SDK troubleshooting and reproducible defect reporting

• Python experience
• 3D experience
• AI/LLM or external‑service integration experience
