The successful candidate will take designs from early concept through detailed design, fabrication, integration, and test, producing prototypes built to the standard of production hardware. This role suits engineers who enjoy variety, move comfortably between programs, and want to see their designs leave the lab and perform in the field.

Key Responsibilities:

• Develop mechanical concepts and detailed designs for enclosures, structures, mounts, housings, and mechanisms supporting electronic, RF, and sensor payloads.
• Produce 3D models, assemblies, and fully dimensioned 2D drawings using GD&T in accordance with ASME Y14.5.
• Perform engineering analysis including tolerance stack-ups and structural, thermal, and environmental assessments to inform design decisions.
• Select materials, finishes, and manufacturing processes appropriate to cost, schedule, and operating environment.
• Prepare fabrication packages and work directly with machine shops, additive manufacturing sources, and outside vendors through build and inspection.
• Lead mechanical integration and support assembly, bring-up, and test of prototype hardware in the lab and in the field.
• Design for environmental requirements such as shock, vibration, sealing, and thermal management, and support qualification testing.
• Collaborate closely with RF, embedded, and systems engineers to resolve packaging, interface, and integration challenges.
• Own mechanical work packages, document assumptions and limitations, and brief findings to technical leads and customers.
• Contribute to proposals and technical concept development for new business.
• Mentor junior engineers and support a culture of disciplined, production-minded design.
• Use AI-enabled tools responsibly in accordance with company policy.

Required Qualifications:

• Bachelor’s degree or higher in Mechanical Engineering or a closely related discipline.

• Strong command of GD&T, drawing standards, and tolerance analysis.
• Hands-on experience taking designs through fabrication, assembly, and test.
• Strong problem-solving skills and ability to work effectively across multidisciplinary teams.
• Must be able to obtain and maintain a DoD Secret clearance.

Desired Skills:

• Active DoD Secret clearance.
• Experience with Creo.
• Experience across multiple CAD platforms.
• Experience with FEA and thermal analysis tools such as ANSYS, Creo Simulate, or SolidWorks Simulation.
• Experience designing for military environmental standards such as MIL-STD-810.
• Experience packaging electronics, RF hardware, or antenna systems.
• Experience with sealed or pressure-rated enclosures for maritime or undersea use.
• Familiarity with additive manufacturing, rapid prototyping, and machining processes.
