Testing (System & Cell) Engineer

Mission:

We are developing a next-generation battery energy storage system for commercial and grid-scale applications. This role supports both system-level validation of energy storage racks and cell-level testing activities in our U.S. laboratory. This is a hands-on engineering role operating across system and component testing in a fast-evolving R\&D environment.

1) Position Targets / Outcomes:

• System-Level Testing \& Validation
• Execute validation testing on 1500V DC energy storage vessels and racks
• Support functional verification, protection logic testing, and performance validation
• Perform system troubleshooting and fault analysis
• Coordinate test results and technical findings with the global-based system engineering team

• Cell-Level Testing \& Documentation
• Testing battery cell performance, editing cycling test procedures, and supervising data collection.
• Analyzing and summarizing test data, developing data analysis templates, and plotting data curves.
• Building testing platforms using data acquisition equipment, power supplies, sensors, and other hardware to meet R\&D testing requirements.
• Managing and documenting battery testing procedures, including defining test steps and troubleshooting test failures. Able to clearly communicate technical matters, scheduling considerations, deliverables, and technical requirements.
• Responsible for the quality and reliability of test results. Identify abnormal results potentially caused by equipment issues.

• Laboratory Support
• Installation, debugging, regular maintenance, and follow-up on troubleshooting of laboratory equipment.
• Complying with and maintaining standard operating procedures to ensure the lab remains safe, clean, and orderly.
• Developing usage plans for test equipment based on testing requirements, including battery cell testing system channels and high/low temperature environmental chambers.
• Collaborating with mechanical engineers and equipment suppliers to design, assemble, and document battery test fixtures.

2) Requirements:

• Bachelor’s or Master’s degree in Electrical Engineering, Mechanical Engineering, or related field
• 2–5 years of experience in system testing, power systems, battery systems, or laboratory testing environments
• Hands-on experience working with high-voltage DC systems (1000V\+ preferred; 1500V strongly preferred)
• High-voltage safety training or certification (NFPA 70E or equivalent)
• Experience with laboratory instrumentation and test equipment
• Ability to interpret electrical schematics and system diagrams
• Strong troubleshooting skills and structured problem-solving approach

3) Ideal Mindset \& Competencies

• Strong hands-on engineering mindset
• Comfortable operating across system and component testing scopes
• Able to work independently in an R\&D environment
• Effective communicator across geographically distributed teams
• Structured in documentation and reporting
• Calm and systematic under field troubleshooting conditions
• Flexible and adaptable as testing priorities evolve
