Senior Battery Engineering Technician

About the role

Responsibilities

• Design, assemble, and validate battery prototypes at module and pack level — supporting engineering and validation programs.
• Build and execute test setups for electrical, thermal, and thermal runaway (TR) testing, including applying sensors and thermocouples to test articles.
• Build test articles, fixtures, and jigs; rework parts and assemblies as needed.
• Build systems enclosures and securing harnesses for test stands and test assets.
• Operate and maintain lab equipment including ultrasonic/spot welders, power supplies, and pack cyclers (Arbin, BioLogic, Chroma, or similar).
• Perform EOL testing using pack cyclers.
• Execute verification using hi-pot testers, multimeters (DMM), continuity testers, oscilloscopes, and bench power supplies; interpret results and identify failure modes.
• Document build processes, test data, travelers, and inspection results with strong attention to traceability.
• Collaborate daily with Battery Engineering, Quality, and Manufacturing to resolve issues, implement ECOs, and improve build/test methods.
• Handle, package, label, and dispose of hazardous battery materials in compliance with federal, state, and local regulations.
• Discharge and dispose of batteries following safety procedures.
• Maintain a clean, safe, and organized lab environment; support 5S/lean improvements at the bench level.
• Participate in first-article builds, prototype iterations, and transition-to-production efforts.

Requirements

• 3+ years of hands-on experience in battery or high-voltage systems (modules or packs) in an engineering or manufacturing environment.
• Experience building battery prototypes at the module and/or pack level.
• Proficient in standard electronics test equipment: multimeters, hi-pot testers, resistance meters, oscilloscopes, and AC/DC power supplies.
• Experience with battery test/data monitoring equipment (Arbin, BioLogic, Chroma, or similar cyclers).
• Hands-on experience building fixtures, procuring parts, and preparing samples for test.
• Experience working safely with hazardous materials; formal safety training is a plus.
• Strong mechanical aptitude with experience in precision assembly, fabrication, and use of hand and power tools.
• Experience with PCB assembly and soldering.
• Experience with additive and subtractive manufacturing (3D printing, CNC).
• Strong ability to read and interpret work instructions, wiring diagrams, and basic schematics.
• Detail-oriented with strong documentation habits and comfort working in a fast-paced, iterative environment.
• Strong oral and written communication skills; team-oriented attitude.
• High school diploma or GED equivalent.
• Experience with thermal runaway testing, abuse testing, or post-burn cleanup (including working in Tyvek suits).
• Experience with DO-160G, DO-311A, or UN 38.3 certification testing.
• Familiarity with aerospace/regulated environments: ESD controls, traceability, controlled rework, configuration management.
• Experience with high-voltage systems in automotive, aviation, or energy storage applications.
• Ability to use machine shop equipment: mill, lathe, welding (laser, ultrasonic, spot).
• Experience supporting prototype-to-production scaling and writing/improving work instructions.
• IPC/WHMA-A-620 or IPC-A-610 certification (plus).
• Associate’s or technical degree in engineering or related field (desired but not required).
• Experience with data analysis tools; proficiency in Microsoft Office.
