The successful candidate will work closely with Systems, Electrical, Manufacturing, Test, Quality, and Program Management to deliver products that meet demanding military and aerospace performance, environmental, and reliability requirements.

Responsibilities

Mechanical Design

• Lead the design of aerospace mechanical and electromechanical products from concept through production.
• Design rugged electronic enclosures, thermal management hardware, structural assemblies, and precision mechanical components.
• Perform engineering trade studies balancing performance, weight, manufacturability, reliability, and cost.
• Develop tolerance analyses, mechanical interfaces, fits, and assembly strategies.
• Perform structural analysis using Analytical calculations and FEA to evaluate stress, vibration, fatigue, thermal effects, and structural integrity.
• Develop margins of safety and correlate analytical models with test results.
• Evaluate materials, fasteners, sealing methods, and mechanical interfaces.

Product Development

• Support all phases of product development including requirements, design reviews, detailed design, prototype builds, qualification testing, and production transition.
• Develop engineering documentation, manufacturing drawings, and design packages using SolidWorks and ASME Y14.5 GD&T.
• Support Engineering Change Notices (ECNs) and configuration management activities.
• Design products to meet military and aerospace environmental requirements including vibration, shock, thermal cycling, altitude, humidity, and corrosion.
• Integrate electronics, wiring, connectors, thermal management hardware, and mechanical structures into compact aerospace products.
• Incorporate design practices supporting EMI/EMC, grounding, shielding, environmental sealing, and thermal management.

Manufacturing & Testing

• Support DFM/DFA activities, prototype builds, qualification testing, and production.
• Work with Manufacturing, Quality, Suppliers, and Test Engineering to resolve technical issues and improve product performance.
• Mentor junior engineers and support technical proposals and engineering estimates.

Required Qualifications

• Bachelor's degree in Mechanical Engineering.
• Minimum 7 years of mechanical design experience developing aerospace, defense, or other high-reliability products.
• Experience designing complex mechanical or electromechanical assemblies from concept through production.
• Proficiency with SolidWorks (or equivalent 3D CAD) and ANSYS Mechanical (or equivalent FEA).
• Strong understanding of structural analysis, mechanics of materials, fatigue, vibration, tolerance analysis, materials, fasteners, and environmental sealing.
• Experience creating manufacturing drawings compliant with ASME Y14.5.
• Strong analytical, communication, and problem‑solving skills.
