Description
Position Summary
The Electrical Battery Engineer III is a senior individual contributor responsible for the electrical design, analysis, and validation of battery cells, modules, and pack-level systems used in high-reliability applications (aerospace, defense, and/or industrial energy storage). This role owns technical decisions across the product lifecycle — from concept through qualification and production support — and serves as a technical resource for less-experienced engineers.
Key Responsibilities
- Lead electrical design of battery modules and packs, including cell selection, series/parallel configuration, protection circuitry, and BMS (Battery Management System) integration
- Perform electrical analysis: voltage/current distribution, thermal-electrical interactions, impedance, state-of-charge/state-of-health estimation, and failure mode analysis (FMEA)
- Develop and execute test plans for electrical performance, safety, and environmental qualification (e.g., abuse testing, overcharge/short circuit, vibration, thermal cycling) in accordance with standards such as MIL-PRF, DO-311, UN 38.3, or UL 1642/2580
- Support NDAA/DFARS compliance efforts, including sourcing traceability for cells and components (relevant to defense-focused battery programs)
- Collaborate with mechanical, thermal, and systems engineering teams to ensure integrated pack design meets performance, safety, and regulatory requirements
- Create and maintain engineering documentation: schematics, wiring diagrams, test reports, and design verification records
- Support root cause investigations for field or production issues and implement corrective actions
- Interface with customers and suppliers on technical requirements, design reviews, and qualification data
- Mentor junior engineers (Engineer I/II) and review their design and test work
- Support new product introduction (NPI) and transition of designs from prototype to production
Requirements
Required Qualifications
- Bachelor's degree in Electrical Engineering, Electrochemical Engineering, or related Field (Master's preferred)
- 5–8+ years of experience in battery/energy storage system design, preferably in aerospace, defense, EV, or industrial applications
- Strong working knowledge of lithium-ion and/or other advanced cell chemistries
- Experience with BMS design/integration, protection circuit design, and electrical safety analysis
- Proficiency with circuit development, simulation and analysis tools (e.g., Altium Designer, MATLAB/Simulink)
- Familiarity with relevant industry/military standards (MIL-STD-810, DO-160, UN 38.3, UL, IEC 62133)
- Strong documentation and technical writing skills
- Ability to obtain/maintain a security clearance or meet ITAR/EAR requirements, if applicable
Preferred Qualifications
- Experience with NDAA-compliant battery programs and Chinese-cell-component exclusion requirements
- Hands-on experience with battery pack manufacturing and laser welding processes
- Exposure to both high-voltage and low-voltage battery system architectures
- Six Sigma / Lean manufacturing familiarity
- Prior experience in a regulated or defense-contracting environment (ITAR/EAR, DFARS)
Physical/Work Environment
- Primarily office/lab environment with occasional time on the production floor
- Occasional travel for customer meetings, supplier audits, or qualification testing
Skills Required
- Expertise in Batteries and Energy Storage including knowledge of charging systems and performance optimization
- 10+ years of experience as an Electrical or Electronic Engineer
- Experience with electrical CAD tools (e.g., Altium Designer)
- Experience with simulation software (MATLAB/Simulink)
- Programming experience in C++ or Python
- Strong foundation in power system design and circuit analysis
- Proven R&D experience delivering innovative engineering solutions
- Demonstrated experience preparing and presenting technical reports
- Direct experience developing, designing, modifying, installing, testing, evaluating, and operating electrical/electronic/systems equipment
- Experience performing test and evaluation of systems, equipment, and components and compiling/analyzing test data
- Experience reviewing, analyzing, developing, and applying engineering specifications, policies, standards, or procedures
- Bachelor's degree or higher in Electrical Engineering, Materials Science, or related field
- Desired 3+ years of experience specifically with Batteries and Energy Storage
- Familiarity with ISO9001 and AS9100 quality systems
- U.S. Citizenship (no visa sponsorship)
