• Hands-on experience with at least one
CAD API / third-party automation SDK

REST API design and consumption
— Web API, JSON serialisation, OAuth2 / JWT authentication against PLM endpoints

• Strong analytical and problem-solving skills — ability to diagnose crashes, memory leaks, and race conditions in long-running desktop processes





• Expertise in performance profiling and fine-tuning — CPU and memory profiling of Windows processes, identifying bottlenecks in CAD API traversal and PLM sync operations

Git
and branching workflows — feature branches, pull requests, and code review in Azure DevOps
