Responsibilities
Lead the mechanical design, and development of various battery mechanical systems, including battery cells, module design, module housings, high voltage distribution and full pack assemblies using advanced CAD tools (e.g. NX)
Develop innovative and weight-optimized structural solutions to meet aircraft-level vibration, shock, and crash safety requirements
Create and manage detailed engineering drawings and specifications, applying a high standard of Geometric Dimensioning and Tolerancing (GD&T)
Generate high quality DFMEA's and DVP&R's
Define and execute comprehensive validation and verification test plans (mechanical, environmental, and abuse testing) to qualify designs for aerospace applications
Collaborate cross-functionally with Electrical, Thermal, and System Integration teams to ensure seamless integration of the battery system into the aircraft structure
Ensure all designs meet relevant aerospace safety and certification standards (e.g., FAA, EASA, DO-160, DO-311, etc.)
Support the transition of designs from prototype to high-volume manufacturing, focusing on Design for Manufacturing (DFM) and Design for Assembly (DFA)
Drive program schedule, timelines. Ensure releases are on time to meet vehicle program milestones
Mentor junior engineers and serve as a technical resource within the mechanical engineering team
Qualification
Required
Minimum of 2+ years of experience in mechanical engineering design, with a significant focus on high-voltage battery systems (cell, module, or pack level)
Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a closely related technical field
Proficiency in a mechanical CAD tool (e.g., Siemens NX, CATIA)
Proficiency with FEA software and hand calculations in structural and thermal analysis using industry-standard FEA/CFD software (e.g., ANSYS, Abaqus, Star-CCM+)
Deep understanding of structural mechanics, fatigue analysis, and thermal management principles as applied to electrochemical systems
Excellent written and verbal communication skills, including the ability to present complex technical information clearly
Strong problem-solving skills and the ability to perform root cause analysis
Ability to work independently and collaboratively in a fast-paced, dynamic environment
Preferred
Prior experience designing components for certified aerospace or high-reliability automotive/EV applications
Familiarity with aerospace certification processes and design standards (e.g., DO-160, DO-311A, MIL-STD, UN 38.3, IEC standards)
Master's or Ph.D. degree in Mechanical Engineering or a specialization relevant to energy storage
Hands-on experience with design for sealing and ingress protection (IP ratings)
Experience with BMS enclosure and interconnect design
Knowledge of manufacturing processes unique to battery pack construction (e.g., laser welding, potting, sealing)
