The Engineering Systems and Tools team at Anduril Industries is looking for an NX Developer to design, build, and maintain internal systems, applications, and infrastructure across the enterprise.
As an NX Developer, you will develop customizations, automation, and administrative tooling for the Siemens NX CAD environment to make it faster, smarter, and more reliable.
You will write real code using NXOpen API, Python, and C++, own the full lifecycle of internal developer tools, and work directly with mechanical and electrical engineers.

Design, develop, and maintain NX Open API customizations (NX Open C/C++, NX Open Python, NX Open .NET) to automate repetitive design tasks and enforce engineering standards
Build and manage NX CAD administrative tools including templates, part families, reuse libraries, and check-mate rules to ensure consistency across the engineering organization
Create custom NX dialogs, menus, and toolbars that streamline workflows for mechanical and electrical design teams
Develop journal-based automation scripts and NX Open applications to accelerate modeling, drafting, and BOM generation processes
Collaborate with PLM engineers to ensure seamless NX–Teamcenter integration in managed mode, including classification, naming rules, and revision workflows
Work with a high-functioning team of solution engineers and cross-functional teams with an emphasis on finishing business-critical projects
Help troubleshoot NX technical issues including those related to deployment, site configuration, custom toolkit distribution, and ongoing end-user support

5+ years of experience in a CAD development role, ideally in a fast-paced engineering or manufacturing environment
Degree in Computer Science, Mechanical Engineering, Information Systems, or related technical degree
Proficiency in NX Open API development using one or more of: C/C++, Python, Java, or .NET (C#/VB.NET)
Hands-on experience with NX CAD administration including templates, drafting standards, part families, reuse libraries, and role-based configurations
Experience creating and maintaining NX journaling scripts and custom automation toolkits
Strong understanding of CAD data management concepts including naming conventions, revision control, and BOM structures
Ability to empathize with end-users, to turn needs into features, and to balance user experience with engineering constraints

Experience with Siemens Teamcenter integration in NX managed mode, including classification, workflows, and naming rules
Familiarity with NX Check-Mate for automated design validation and quality checks
Experience with NX deployment and site-level configuration (ugii_env, custom directories, toolkit distribution)
Knowledge of GRIP or KF (Knowledge Fusion) programming within NX
Experience integrating CAD tools with downstream systems (PLM, ERP, MES, etc.)
Exceptional communication and interpersonal skills
Strong analytical and problem-solving skills
Ability to navigate ambiguity, resolve user issues, and work autonomously to solve problems
