Our client is a growing precision manufacturing company specializing in the design and production of high-performance electric motors for aerospace and defense applications. They're looking for a Senior Mechanical Engineer to join their engineering team and take ownership of mechanical design work across the full product lifecycle — from concept through qualification and production support.

What You'll Do

• Design electric motors in close collaboration with electromechanical design engineers to meet customer performance requirements
• Design rotors, housings, endcaps, and other mechanical assemblies
• Size and select bearings to meet load and life requirements
• Create and revise engineering drawings with proper GD&T; maintain accurate BOMs
• Design manufacturable, cost-effective hardware — balancing tolerance stack-ups, assembly ease, materials, manufacturing methods, thermal/vibration environments, and mistake-proofing
• Run preliminary analysis (hand calcs and FEA) to validate designs
• Investigate and resolve non-conforming hardware and production/vendor issues
• Lead or support failure investigations
• Develop and approve assembly, test, and qualification processes
• Interface directly with internal and external customers on product requirements and changes
• Participate in design reviews and support new business proposals

What You Bring

• Bachelor's degree in Mechanical Engineering
• Experience in 3D modeling of mechanical components/assemblies (CREO strongly preferred)
• Experience with Brushless DC (BLDC) motor design and operation
• Experience with Finite Element Analysis (FEA) — structural, thermal, and dynamic
• Strong technical problem-solving using a methodical, data-driven approach
• Working knowledge of manufacturing processes: additive manufacturing, casting, milling, turning, grinding, drilling
• Strong organizational skills with the ability to manage multiple concurrent projects
• Excellent verbal and written communication skills; comfortable presenting in cross-functional design reviews
• Must be a U.S. Citizen (ITAR/export control requirement)

Nice to Have

• Prior experience in aerospace, defense, or other highly regulated manufacturing environment
• Leadership experience coordinating across engineering, manufacturing, quality, and purchasing teams

Work Environment

• Split between professional office and manufacturing/machine shop settings
• Some exposure to fluids, fumes, noise, vibration, and moving mechanical parts typical of a machine shop
• Ability to stand for extended periods (7-8 hrs/day), walk, bend, and occasionally lift up to 50 lbs
• ~15% travel

Benefits

Competitive base salary plus quarterly bonus, medical/dental/vision, life and disability insurance, 401(k) with company match, generous tuition assistance, paid vacation/sick/personal time, paid holidays, and flexible/compressed work week options.
