Experience: 3+ yrs
Location: Bengaluru
Job Type: Full-time
We are looking for a highly skilled CAD Software Development Engineer with 3+ years of hands-on experience in CAD API programming, software customization, and Windows-based application development. The role focuses on building and maintaining reliable CAD automation systems, integrating multiple CAD platforms, handling complex file formats, and improving the performance and reliability of 3D processing and visualization workflows.
The ideal candidate will have strong production experience with C++ and C# , deep expertise in at least one major CAD API such as SolidWorks API, Creo Toolkit, NX Open, or CATIA CAA, and strong debugging skills across processes, memory, COM, and RPC layers.
Requirements
Key Responsibilities
โขDevelop, maintain, and enhance CAD automation and API integration solutions using C# and C++.
โขManage SolidWorks instances running as headless, multi-process services with robust process lifecycle management.
โขDiagnose and resolve RPC errors, COM failures, application crashes, process hangs, and memory-level issues on Windows.
โขBuild reliable process-pool mechanisms with health checks, automatic recovery, graceful degradation, and kill-and-restart capabilities.
โขExtend CAD automation capabilities including STEP export, JSON export, drawing generation, and geometry processing .
โขDevelop and maintain integrations with multiple CAD platforms, including SolidWorks, Creo, NX, CATIA, and similar systems.
โขBuild a common abstraction and integration layer to support multiple CAD engines and reduce platform-specific dependencies.
โขDebug and resolve GLB/GLTF, STEP, and other CAD file conversion and export issues .
โขHandle CAD files generated across different software platforms and versions, including CATIA, Creo, Fusion, NX, and others.
โขWork with B-Rep geometry, solid and surface bodies, feature recognition, geometry validation, and surface/solid detection .
โขImprove 3D viewer reliability, including face selection, bounding-box calculations, rendering performance, ray casting, and geometry interaction.
โขEnsure compatibility across multiple SolidWorks versions , including API differences and backward-compatibility requirements.
โขDesign and implement integration approaches for new CAD platforms, including C++-based toolkits such as Creo Toolkit.
โขDefine effective interaction between C# and C++ components and establish reusable cross-CAD data models.
โขParticipate in debugging, code reviews, architecture discussions, regression testing, and continuous improvement of CAD processing systems.
โขUse modern AI-assisted development tools to accelerate API research, debugging, code exploration, and development.
What Makes You a Great Fit
โข3+ years of professional experience in CAD software development, CAD customization, or CAD API programming; CAD software usage alone is not sufficient.
โขStrong production-level programming experience in C++ and C# .
โขHands-on experience with COM interop, Windows development, process management, services, RPC, and system-level debugging .
โขDeep expertise in at least one CAD development API such as SolidWorks API, Creo Toolkit, NX Open, CATIA CAA , or an equivalent platform.
โขUnderstanding of CAD application limitations around multithreading, process isolation, concurrency, and application stability , with experience implementing practical workarounds.
โขStrong knowledge of STEP file formats, B-Rep geometry, solid versus surface bodies, and basic feature recognition .
โขExperience troubleshooting CAD files and geometry generated by different CAD systems and software versions.
โขStrong understanding of Windows processes, memory behavior, COM objects, RPC communication, and application lifecycle management.
โขAbility to design scalable integration architectures across multiple CAD platforms.
โขStrong analytical, debugging, troubleshooting, and problem-solving skills.
โขComfortable working with complex, poorly documented APIs and independently researching technical problems.
โขFamiliarity with modern AI-assisted development tools such as Cursor, GitHub Copilot, or Claude and an ability to use them effectively for research, debugging, and rapid iteration.
โขStrong ownership, attention to detail, and ability to work independently on technically challenging engineering problems.
