Job Title:

Mechanical Designer – Siemens NX / Teamcenter (Sentinel Program) Job Description

This role supports a high-visibility defense program as a Mechanical Designer, using Siemens NX and Teamcenter in a fully digital, paperless environment. You will create and revise mechanical and electro-mechanical designs, apply GD&T standards daily, and contribute to mission-critical systems that support national defense and space launch initiatives. The position requires a proactive designer who can work with minimal supervision, collaborate closely with engineers and other designers, and consistently deliver accurate, production-ready CAD models and drawings.

• Develop layouts and prepare detailed and assembly drawings of moderate complexity for mechanical and electro‑mechanical components using Siemens NX.
• Create, revise, and maintain 3D models and 2D drawings in accordance with standard drafting practices and established policies and standards.
• Apply Geometric Dimensioning and Tolerancing (GD&T) methods daily to ensure proper fit, form, and function of components and assemblies.
• Use CAD and PLM software, including Siemens NX (Unigraphics) and Teamcenter, in accordance with defined drafting and configuration management standards.
• Work closely with designers and engineers to translate design concepts and requirements into accurate models, drawings, and product definition.
• Gather missing information and clarify requirements proactively to complete assignments without waiting for direction.
• Support the design of mechanical and electro‑mechanical components that may include relatively simple parts as well as moderately complex assemblies.
• Prepare Product Manufacturing Information (PMI) within NX for paperless manufacturing environments, including work instructions, dimensions, and data references when applicable.
• Perform work in alignment with standard drafting practices, internal procedures, and program‑specific guidelines.
• Collaborate with team members to ensure consistency, quality, and adherence to program standards across all design deliverables.
• Potentially hand off work to and provide guidance or oversight to lower‑level drafters as needed to meet project deadlines.
• Contribute to design efforts that support defensive systems and launch systems for government and military customers, including next‑generation interceptor and strategic deterrent programs.
• Maintain accurate documentation and data within the PLM environment, ensuring traceability and proper revision control.
• Identify issues in design data early, communicate risks or discrepancies, and work with stakeholders to resolve them efficiently.
• Demonstrate a proactive approach by anticipating next steps, seeking out needed information, and driving assigned work to completion without requiring constant direction.

• 5–10 years of mechanical design experience in military, Department of Defense (DoD), or aerospace environments.
• Strong proficiency with Siemens NX (Unigraphics), with at least 2 years of recent, hands‑on experience; familiarity with NX 9.0 or more recent, with current use of NX 2412 preferred.
• Minimum 8/10 proficiency level with Siemens NX and Teamcenter, demonstrated through recent project work.
• Daily, practical experience applying Geometric Dimensioning and Tolerancing (GD&T) in design and drafting activities.
• Solid understanding of GD&T methods to ensure proper fit, form, and function of mechanical and electro‑mechanical components.
• Proficient use of CAD and PLM (vault) software tools, specifically Siemens NX and Teamcenter, in a production design environment.
• Ability to work with minimal supervision, plan next steps independently, and proactively obtain missing information needed to complete tasks.
• Experience performing work in accordance with standard drafting practices and established engineering and configuration standards.
• Ability to collaborate closely with designers and engineers to develop layouts and detail drawings of moderate complexity.
• Eligibility to obtain a secret security clearance, with U.S. citizenship required for clearance purposes.

• Experience with Product Manufacturing…
