Senior NX Open DeveloperYou will own the automation layer of a parametric design application built inside Siemens NX, taking the build from requirements through to a deployed plugin.

Location: Remote / Kolhapur, Maharashtra · Experience: 8+ years · Type: Full time

What you will build• A Siemens NX plugin with its own ribbon tab, dialogs and menu controls, written in C# against NX Open (.NET)
• Parametric generation of complex, multi-feature component geometry (patterned features, swept profiles, blended transitions, pockets and inserts) driven from a master profile
• Template instantiation and parameter-driven regeneration that survives wide swings in input values without build failures
• A preprocessor that tessellates the model, tags faces, and exports geometry and parameters as XML with reliable per-face identifiers
• Import and export paths to external data sources, including Excel and CSV parameter tables
• Installer, deployment packaging and documentation for engineers who will use the tool daily





What we need you to have 5+ years building production automation against NX Open (.NET or C++), not journaling or recorded scripts alone
C# / .NET
Strong, with real experience structuring a codebase that others will maintain
Parametric CAD
Deep understanding of feature trees, expressions, constraints, and why regeneration fails
Geometry
Comfortable with boundary blends, pattern-along-curve, variable fillets, swept and multi-body operations
Delivery
Has shipped a CAD plugin that real engineers used, not only internal prototypes
Communication
Can work directly with a client's design engineers and explain trade-offs clearly in English

What would set you apart• Tessellation APIs, face or surface tagging, and getting identifiers to persist through a geometry rebuild
• XML schema work, particularly feeding a downstream simulation or FEA tool
• Background in a domain with hard geometric constraints, such as tooling, turbomachinery or precision-engineered components
• Creo
