We are seeking a Drone Battery Pack Design Engineer II to join our Electric Propulsion Subsystem (EPS) team. In 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
