This multi-dimensional approach enables us to solve the most critical and large-scale challenges across the aerospace & defense, automotive, energy, hi-tech, healthcare, medical devices, rail and semiconductor industries. We are looking for humble geniuses, who believe that engineering has the potential to make the impossible possible; innovators, who are not only inspired by technology and innovation, but also perpetually driven to design, develop, and test as a trusted partner for Fortune 500 customers. As a team of remarkably diverse engineers, we recognize that what we are really engineering is a brighter future for us all. If you want to contribute to meaningful work and be part of an organization that truly believes when you win, we all win, and when you fail, we all learn, then we’re eager to hear from you. The achievers and courageous challenge-crushers we seek, have the following characteristics and skills: Role Summary: We are seeking a hands-on Battery Test Engineer to support battery-related validation and characterization activities. Working closely with the battery systems lead, this role focuses on planning, executing, and reporting on laboratory testing of battery cells, packs, charging systems, and associated power electronics. The ideal candidate is meticulous, safety-conscious, and comfortable working in a fast-paced hardware development lab.

Requirements

Degree in Electrical Engineering, Mechanical Engineering, or a related field, or equivalent hands-on experience.
Working knowledge of battery fundamentals: cell chemistry, capacity, internal resistance, state-of-charge, charge/discharge behavior.
Hands-on experience with lab instrumentation and electrical measurement.
Comfortable interpreting schematics, power trees, and datasheets.
Strong data-analysis skills (e.g., Python, MATLAB, or spreadsheet-based tools).
Detail-oriented, organized, and able to document work clearly.
U.S. citizenship is required.

Nice To Haves

Experience with battery cyclers and automated test systems.
Familiarity with power-management ICs, chargers, and fuel-gauge circuits.
Experience with thermal chambers and temperature-controlled testing.
Scripting/automation of test setups and data pipelines.
Prior experience in a hardware validation or bring-up environment.

Responsibilities

Set up and execute battery characterization tests: charge/discharge cycling, capacity, internal resistance, load sweeps, and temperature-dependent behavior.
Operate lab instrumentation (source meters, electronic loads, battery cyclers, data acquisition systems, oscilloscopes, thermal chambers) and maintain calibration and safety standards.
Perform bench bring-up, functional testing, and characterization of power supply circuits, regulators, and power rails.
Build and maintain test fixtures, harnesses, and instrumentation for cells, packs, chargers, and power rails.
Capture, process, and analyze test data; identify anomalies, trends, and failure signatures; summarize findings in clear reports.
Support charging-system, fuel-gauge, and battery-management validation, including brownout, peak-power, and protection behavior.
Assist in root-cause investigations and characterization of power/battery issues discovered during bring-up and validation.
Document test plans, procedures, and results; keep organized records of raw data and derived metrics.
Follow all battery-handling, storage, and lab-safety protocols.
