We are seeking a Battery Testing Engineer to plan, execute, and analyze battery tests at the cell, module, and pack levels. This role is highly hands-on and data-driven, focusing on performance validation, safety testing, and reliability of battery systems throughout development and production phases.
Key Responsibilities
Develop and execute test plans for battery cells, modules, and packs, including performance, lifecycle, safety, and environmental testing.
Support prototype builds and validation testing.
Operate battery test equipment such as cyclers, thermal chambers, power supplies, load banks, and DAQ systems.
Analyze test data to evaluate capacity, efficiency, degradation, thermal behavior, and failure modes.
Define test procedures, acceptance criteria, and reporting formats in alignment with product requirements and standards.
Support abuse, stress, and safety testing (thermal, electrical, mechanical) in controlled lab environments.
Investigate test anomalies and failures, perform root-cause analysis, and support corrective actions.
Collaborate with mechanical, electrical, and thermal engineers to correlate test results with design assumptions.
Maintain test documentation, lab records, and calibration status of equipment.
Requirements: Qualifications
Bachelors degree in Electrical Engineering, Mechanical Engineering, or a related field.
Experience with battery testing at cell, module, or pack level.
Strong understanding of lithium-ion battery behavior, degradation mechanisms, and safety considerations.
Hands-on experience with battery test systems and lab equipment.
Ability to analyze and interpret large datasets using tools such as Python, MATLAB, or Excel.
Familiarity with battery management systems (BMS) and related measurements (voltage, current, temperature).
Preferred Qualifications:
Familiarity with battery system components and requirements: cells, modules, enclosures, etc.
Experience designing test fixtures or instrumentation setups.
Experience with automation or scripting for test execution and data processing.
Personal Attributes:
Detail-oriented and methodical with a strong safety mindset.
Curious and analytical, with a passion for understanding battery behavior.
Comfortable working hands-on in a lab environment.
Strong communicator who can clearly present test results and conclusions.
This position is open to all candidates.
