Job description

Our client is seeking a Mid-Level Mechanical Engineer to support the design, development, and prototyping of mission equipment for U.S. Department of Defense applications. The engineer will work as an integrated member of a combined Government and contractor engineering team supporting the development of a mission pallet proof-of-concept system.

This is a hands-on engineering position supporting the complete design and prototyping lifecycle, including concept development, detailed mechanical design, 3D modeling, technical data package development, prototype fabrication, and manufacturing support. The position requires full-time, on-site support at the Government's Prototype Integration Facility (PIF).

Primary Responsibilities

• Develop mechanical designs for DoD systems, subsystems, assemblies, and equipment.
• Develop and evaluate design concepts based on system requirements, interfaces, operational constraints, and manufacturability.
• Create detailed 3D CAD models, assemblies, and engineering drawings.
• Develop and maintain Technical Data Packages (TDPs), including drawings, bills of materials, specifications, and associated engineering documentation.
• Perform mechanical design and packaging of components, structures, mounting provisions, and related hardware.
• Apply Geometric Dimensioning and Tolerancing (GD&T) and appropriate engineering drawing standards.
• Support prototype fabrication, assembly, integration, and manufacturing activities.
• Work directly with machinists, fabricators, technicians, and other engineering disciplines to resolve design and manufacturing issues.
• Evaluate prototype hardware and incorporate lessons learned and test results into subsequent design iterations.
• Participate in design reviews, technical meetings, and integrated product team activities.
• Coordinate mechanical interfaces with electrical, systems, manufacturing, and integration personnel.
• Support configuration management and documentation of design changes throughout the development lifecycle.
• Provide responsive engineering support during prototype build and integration activities.

Required Qualifications

• Active DoD Secret security clearance.
• Bachelor's degree or higher in Engineering from an accredited institution; Mechanical Engineering strongly preferred.
• 3-6 years of relevant engineering experience.
• Demonstrated experience developing mechanical designs for Department of Defense systems, platforms, or equipment.
• Experience performing detailed mechanical design using 3D CAD modeling software.
• Experience developing engineering drawings and supporting documentation suitable for fabrication and manufacturing.
• Experience supporting prototype development, fabrication, integration, or manufacturing.
• Working knowledge of engineering drawing practices, GD&T, configuration control, and technical data development.
• Ability to work effectively as part of a multidisciplinary Government/contractor engineering team.
• Ability to work full-time on-site at the Government facility.

Preferred Qualifications

• Bachelor's in Mechanical Engineering.
• Experience supporting U.S. Army missile, missile defense, aviation, or other weapon system programs.
• Experience supporting engineering activities within an Army prototype development or integration environment.
• Experience developing complete Level III Technical Data Packages or equivalent production-level engineering documentation.
• Experience designing structures, equipment racks, mission pallets, mounting systems, or other mechanically integrated mission equipment.
• Familiarity with DoD and Army engineering, drawing, manufacturing, and configuration management requirements.
• Experience supporting rapid prototyping programs where designs progress quickly from concept through fabrication and integration.
• Experience working directly with manufacturing personnel to resolve producibility, fit, tolerance, and assembly issues.
