Mechanical Design Engineer Senior

Description:

You will be the Senior Mechanical Engineer for the Missiles & Fire Control (MFC) New Missile Team. Our team drives the concept to production journey for next generation missile systems, delivering robust mechanical designs, model based data, and validated tolerances that keep the program on schedule and on budget.

What You Will Be Doing

As the Senior Mechanical Engineer you will own every mechanical design artifact that fuels the program. Working side by side with product engineers, production planners, and the global supply chain, you will turn concepts into solid model geometry, Model Based Design (MBD) deliverables, and tolerance analyses that enable rapid, reliable manufacturing. The role sits in the core design organization and collaborates across engineering, production, and logistics, with occasional travel to supplier sites and test facilities.

Your responsibilities will include:

• Build and maintain 3 D CAD models and 2 D drawings in the Digital Product Lifecycle Management (dPLM) environment.
• Generate release ready engineering documents (drawings, BOMs, assembly part lists) for fabrication and procurement.
• Perform tolerance stack up and fit analyses to guarantee manufacturability and reliability.
• Apply MBD principles, embedding GD&T and feature control frames directly in the CAD model.
• Coordinate design changes across cross functional teams and keep dPLM baselines current.
• Provide Production Planning, Operations, and Global Supply Chain with accurate, up to date design data and troubleshooting support.
• Identify and implement innovative design solutions to resolve complex mechanical challenges.
• Lead design reviews, incorporate stakeholder feedback, and secure formal engineering release approvals.
• Ensure all documentation complies with DoD and Lockheed Martin standards.
