10+ years of demonstrated mechanical design experience; defense, aerospace, or a comparable regulated industry is preferred.
Proficiency in SolidWorks, including assembly modeling and detailed drawing creation.
Strong working knowledge of GD&T per ASME Y14.5 and ability to apply tolerance schemes that meet inspectability and producibility requirements.
Experience performing FEA using SolidWorks Simulation and interpreting results to guide design decisions.
Experience performing tolerance stack-up analyses to validate mechanical fit and function.
Working familiarity with manufacturing processes such as machining, sheet metal, casting, and additive manufacturing, and their design implications.
Demonstrated experience leading mechanical design efforts and mentoring less experienced engineers.
Strong written and verbal communication skills and ability to interact effectively with stakeholders.
Self-starter and team player able to work with engineers, integrators, analysts, and others in a dynamic, fast-paced environment.
U.S. citizenship and an active Secret security clearance, with ability to maintain the required clearance.

Responsibilities

Develop 3D parametric models, detailed part drawings, and assembly drawings in SolidWorks from concept through production release.
Produce engineering drawings with complete GD&T per ASME Y14.5, including dimensions, tolerances, datum schemes, and surface-finish callouts suitable for fabrication and inspection.
Perform worst-case and statistical tolerance stack-up analyses to verify fit, function, and assembly feasibility before release.
Conduct structural, modal, and thermal finite element analyses to validate designs against load, vibration, shock, and thermal-environment requirements.
Select materials, fasteners, and commercial off-the-shelf components based on mechanical, environmental, manufacturing, and cost requirements.
Apply Design for Manufacturability and Design for Assembly principles in collaboration with manufacturing and supplier-quality teams to reduce cost and assembly risk.
Lead prototype builds, design verification testing, and iterative design refinement to validate performance before production.
Prepare and present designs at preliminary and critical design reviews, incorporating feedback into the released baseline.
Author engineering change proposals and notices and maintain mechanical design baselines under formal configuration management.
Collaborate with electrical, systems, and software engineering, manufacturing, and test teams to ensure mechanical interfaces meet program requirements.
Provide technical leadership on mechanical design efforts, establish design standards and best practices, and mentor less experienced engineers.
Perform other duties as assigned.
