Engineering Technician
- Battery Test

We are seeking an Engineering Technician
- Battery Test to support the execution of lithium-ion battery testing across the cell, module, and high-voltage (HV) pack levels. This role is highly hands-on and focused on building, operating, maintaining, and troubleshooting battery test systems while working closely with test engineers and cross-functional engineering teams.

This is a role for you if you enjoy working in a laboratory environment, have strong mechanical and electrical aptitude, and take pride in building reliable test setups and producing high-quality test data. Previous experience with lithium-ion battery testing is preferred, while high-voltage battery experience is a plus but not required.

Responsibilities include:

• Build, install, and operate battery test setups under the guidance of test engineers.
• Prepare and test lithium-ion cells, modules, and high-voltage battery packs.
• Safely install and connect battery hardware, instrumentation, and support equipment.
• Execute battery tests including:
  Performance characterization, Cycle life and aging, Rate capability, Power and resistance testing, Environmental and thermal testing, Validation and durability testing
• Monitor active tests and respond appropriately to alarms, faults, or abnormal test behavior.
• Maintain detailed test logs and document observations throughout testing.

Test Equipment & Lab Support:

• Configure and operate battery cyclers (Maccor, AVL, Neware, or similar systems).
• Assemble test fixtures, wiring harnesses, instrumentation, and support hardware.
• Install thermocouples, voltage taps, current sensors, pressure sensors, and other instrumentation.
• Operate environmental chambers and supporting laboratory equipment.
• Perform routine calibration, maintenance, and troubleshooting of laboratory equipment.
• Help maintain an organized, safe, and efficient battery laboratory.

High Voltage & Lab Safety:

• Follow laboratory safety procedures for battery testing, including HV safety practices where applicable.
• Verify proper test setup before energizing battery systems.
• Perform pre-test inspections and equipment checks.
• Support continuous improvement of laboratory safety procedures and best practices.

Data Collection & Documentation:

• Verify accurate data acquisition from battery cyclers, DAQ systems, and instrumentation.
• Organize and archive test data.
• Assist engineers with basic data review and reporting.
• Record hardware configurations, serial numbers, and test conditions.
• Help develop and improve laboratory work instructions and test procedures.

Troubleshooting:

• Diagnose electrical, mechanical, and instrumentation issues with test setups.
• Replace damaged cables, connectors, sensors, and fixtures as needed.
• Assist engineers with failure investigations and root cause analysis.
• Help improve test reliability, repeatability, and laboratory efficiency.

Cross-Functional Support:

• Work closely with battery test, systems, electrical, mechanical, manufacturing, and BMS engineering teams.
• Support prototype builds and engineering development activities.
• Assist with assembly, disassembly, inspection, and teardown of cells, modules, and battery packs before and after testing.

Qualifications include:

• Associate's degree, technical certification, military technical experience, or equivalent hands-on experience in electrical, mechanical, automotive, or related fields.
• Strong mechanical and electrical aptitude.
• Experience using common laboratory tools and equipment (multimeters, oscilloscopes, power supplies, hand tools, crimpers, etc.).
• Ability to read electrical schematics and mechanical drawings.
• Strong attention to detail and commitment to safety.
• Comfortable working in a hands-on laboratory environment.
• Ability to lift up to 50 lb and work around laboratory equipment and battery systems.

Preferred Qualifications:

• Experience testing lithium-ion cells, modules, or battery packs.
• Experience operating battery cyclers (Maccor, AVL, Neware, or similar).
• High-voltage battery experience or HV safety training.
• Familiarity with CAN communication and basic BMS operation.
• Experience with thermal chambers, DAQ systems, or environmental testing.
• Basic experience with MATLAB,…
