Drone Battery Pack Design Engineer II, Prime Air

We are seeking a Drone Battery Pack Design Engineer II to join our Electric Propulsion Subsystem (EPS) this role you will be a significant and autonomous contributor solving difficult hardware engineering problems related to battery systems. You will design develop and validate battery packs from concept through production working on high-voltage battery systems that push the boundaries of performance reliability efficiency and safety.

This position requires an engineer who demonstrates strong technical depth in battery pack design while also exhibiting the system-level thinking and influence characteristic of our most impactful contributors.

Key job responsibilities
Design & Development

Design the mechanical architecture for high-voltage Li-Ion battery packs including cell arrangement modules enclosures structural supports and interconnections balancing energy density safety and manufacturability
Create 3D models and manufacturing drawings in CATIA with GD&T
Design and integrate thermal management systems and sealed IP-rated enclosures

Analysis & Validation

Perform FEA (structural vibration thermal) and tolerance stack-up analysis
Plan and execute prototype builds validation testing and root-cause failure analysis

Safety & Compliance

Design to high-voltage safety requirements including creepage/clearance isolation and HVIL
Incorporate thermal runaway mitigation and comply with standards (UN 38.3 UL 2580 IEC 62133)
Develop verification test plans against DO-160 and DO-274 and support DFMEA

Collaboration & Process

Partner with electrical BMS systems safety manufacturing and supply chain teams on interfaces DFM/DFA tooling and sourcing
Present at design reviews and maintain documentation and change control in PLM
Support project planning with estimates timelines and risk assessments
Improve cost weight safety and manufacturability

- Bachelors degree in mechanical engineering or equivalent
- 4 years of working in mechanical engineering or equivalent experience
- Demonstrated experience taking a mechanical design from concept through prototype to production.
- Battery pack mechanical design: cell-to-pack architecture module design cell holders busbar integration enclosures and structural support for prismatic cylindrical or pouch cells.

- CAD proficiency (SolidWorks Creo CATIA or NX) for 3D modeling GD&T detailed drawings and tolerance stack-up analysis
- Thermal management design including cooling systems (liquid cold plates air phase-change or immersion) thermal interface materials fast-charge and high-C-rate applications and thermal runaway mitigation
- FEA for stress vibration shock and drop plus scripting and simulation tools (MATLAB Python) for design automation or thermal modeling
- Enclosure and high-voltage design: IP-rated sealing creepage and clearance isolation coordination and interfaces with the BMS contactors fuses HVIL and service disconnects
- Design for manufacturing and assembly including pack joining methods (laser ultrasonic or resistance welding; adhesives; fastening) and supplier work on tooling molding sheet metal die casting or extrusions
- Prototyping bring-up and validation testing (environmental chambers vibration tables HALT/HASS) plus DFMEA and design-for-safety methodology
- Experience with automotive aerospace marine or grid-storage battery systems including how cell chemistry drives mechanical and thermal requirements
