Mechanical Engineer

The Role We are seeking a Mechanical Engineer to design and develop battery modules and propulsion integration systems. This position is open at the Level III or Level IV depending on experience, technical depth, and demonstrated system ownership. You will be responsible for designing hardware that moves from concept through validation and into production, balancing performance, weight, cost, and manufacturability within aerospace certification constraints. What You'll Do Design and develop mechanical systems for battery modules and propulsion integration Own 3D CAD models and generate release‑ready 2D drawings (ASME Y14.5) Perform tolerance stack-ups and configuration management Conduct structural, thermal, and vibration analysis (classical methods + FEA) Develop and execute design verification plans (DVP&R) Support environmental qualification testing (shock, vibration, thermal, altitude) Optimize packaging for weight, volume, cost, and manufacturability Collaborate with electrical, manufacturing, and test engineering teams Interface with suppliers and support production ramp Troubleshoot hardware issues and lead root cause investigations Level Expectations Mechanical Engineer III 4-7 years of mechanical design experience Independently owns subsystem design from concept through production release Advanced SolidWorks proficiency Strong GD&T and tolerance analysis capability Experience designing for high-reliability environments Mechanical Engineer IV 7+ years of progressive mechanical design experience Demonstrated system-level ownership from architecture through qualification Expert-level CAD and FEA proficiency Serves as a technical lead on complex structural and thermal challenges Guides validation strategy and mentors other engineers Required Qualifications Bachelor's degree in Mechanical Engineering Strong proficiency in SolidWorks (modeling, detailing, revision control) Experience designing for manufacturability (machining, sheet metal, molding, casting) Experience performing structural and/or thermal analysis Ability to thrive in a fast‑paced, high‑accountability development environment Preferred Qualifications Experience with DO-160, MIL-STD-810, or similar environmental testing standards Experience with aerospace or high‑voltage propulsion systems Master's degree in Mechanical Engineering #J-18808-Ljbffr Electric Power Systems, Inc.
