Job description

About the company
We are a stealth-mode battery startup developing cutting-edge battery technology. Our mission is to revolutionize battery technology to accelerate the global transition to clean energy. By leveraging innovative materials, advanced manufacturing techniques, and next-generation energy storage architectures, we are building the future of sustainable energy.
About the Role
We are seeking a Battery Systems Engineering Intern to support the development and validation of our battery pack systems. This role provides hands-on exposure to real engineering challenges in a startup environment, including test development, system validation, failure analysis, and cross-functional collaboration.
What You'll Do
  • Help plan, execute, and document engineering tests for battery cells, modules, and pack systems.
  • Design and build test fixtures and experimental setups for electrical, thermal, and mechanical testing.
  • Support process trial experiments to improve system performance and quality.
  • Collect, process, and analyze test data using engineering tools (e.g., Python, MATLAB, Excel, or similar).
  • Assist in root cause investigations using structured problem-solving methods such as 8D.
  • Help with BMS integration into test setups, including wiring, communication, and instrumentation.
  • Assist with system-level engineering activities such as requirements definition, DFMEA, and validation plans.
  • Work with cross-functional teams (mechanical, electrical, systems, manufacturing, and test engineering) to support development activities.
  • Document results and present findings to the engineering teams.

Who You Are
  • Currently pursuing a BS or MS in Electrical Engineering, Mechanical Engineering, Chemical Engineering, or related field
  • Strong interest in battery systems, energy storage, or electrified systems
  • Hands-on experience with lab equipment, hardware, or prototyping
  • Basic understanding of data analysis and experimental methods
  • Strong problem-solving and communication skills

You're the Ideal Candidate if You Have
  • Experience with battery systems, BMS, or power electronics
  • Familiarity with Python, MATLAB, or similar data analysis tools
  • Experience with test instrumentation (DAQs, oscilloscopes, power supplies, etc.)
  • Exposure to systems engineering practices (requirements, FMEA, validation)
  • Experience working in a lab or hardware development environment

Why Join Us
  • Work on cutting-edge battery technology
  • Gain hands-on engineering experience building real hardware
  • Collaborate with a small, highly technical startup team
  • Opportunity to make meaningful contributions to product development

Onsite Expectations
This role is expected to be onsite in our San Jose office every day (M-F).
Expected compensation
Hourly Rate: $45.00 - $55.00
Hourly rate is based on many factors including (but not limited to): market rate, interview performance, level of experience, and geographic location.
We are an equal opportunity employer and we do not discriminate on the basis of race, gender, sexual orientation, gender identity/expression, national origin, disability, age, genetic information, veteran status, marital status, pregnancy or related condition, or any other basis protected by law.
