About the Job

Requirements

A degree in Chemistry, Material Science, or Chemical Engineering, or equivalent experience.
At least five years of hands-on experience in battery cell design, testing, failure analysis, or research and development.
Proficiency with battery testing equipment such as Arbin, Neware, or Bio-Logic.
Proficiency with data analysis tools including Python, MATLAB, and Excel.
Understanding of lithium-ion battery chemistry and failure mechanisms.
Understanding of nondestructive and destructive analytical techniques, including computed tomography, X-ray fluorescence, scanning electron microscopy with energy-dispersive X-ray spectroscopy, differential scanning calorimetry, thermogravimetric analysis, and Fourier-transform infrared spectroscopy.
Problem-solving, communication, and documentation skills.
Ability to work in a fast-paced, cross-functional environment with attention to detail and safety.

Responsibilities

Provide technical guidance to Cell Manufacturing in evaluating cell product quality risks.
Develop and execute test plans to investigate cell-level failure modes, including internal shorts, capacity fade, swelling, thermal runaway, and electrolyte degradation.
Fabricate coin and low-capacity pouch cells in a glovebox environment, and perform production-relevant fault injections on production lines.
Analyze battery cells using diagnostic tools such as scanning electron microscopy, computed tomography, electrochemical impedance spectroscopy, and X-ray fluorescence.
Perform electrical and electrochemical characterization, including cycling, impedance spectroscopy, and charge/discharge profiling, to identify performance anomalies.
Document findings in actionable reports covering root cause analysis, failure mechanisms, and mitigation recommendations.
Collaborate with materials scientists, process engineers, and manufacturing teams to implement corrective actions and prevent recurrence.
Support product and cell test validation programs.

Job Description

We are seeking a detail-oriented Cell Engineer (or Scientist) to join our Global Technical Quality team. The ideal candidate will be responsible for investigating, analyzing, and resolving electrical, mechanical, and chemical issues in lithium-ion battery cells during development, production, and field returns. You will play a critical role in improving cell quality, reliability, safety, and performance by leading defect designations, designing test protocols, and collaborating cross-functionally with R&D, manufacturing, production quality, and reliability teams.

Job Responsibilities

Provide technical guidance to Cell Manufacturing in relation to evaluating cell product quality risks
Develop and execute test plans to probe cell-level failure modes including internal shorts, capacity fade, swelling, thermal runaway, and electrolyte degradation
Fabricate coin and low-capacity pouch cells, within glovebox environment as well as production-relevant production line fault injections
Conduct in-depth analysis on battery cells using advanced diagnostic tools (e.g., SEM, CT, EIS, XRF, etc)
Perform electrical and electrochemical characterization (cycling, impedance spectroscopy, charge/discharge profiling) to identify performance anomalies
Document findings with clear, actionable reports, including root cause analysis, failure mechanisms, and mitigation recommendations
Collaborate with materials scientists, process engineers, and manufacturing teams to implement corrective actions and prevent recurrence
Support product and cell test validation programs

Job Requirements

Degree in Chemistry, Material Science, Chemical Engineering or equivalent experience
5+ years of hands-on experience in battery cell design, testing, failure analysis, or R&D
Proficiency with battery testing equipment (e.g., Arbin, Neware, Bio-Logic, etc)
Proficiency with data analysis tools (Python, MATLAB, Excel)
Understanding of lithium-ion battery chemistry and failure mechanisms
Understanding of non-destructive and destructive analytical techniques (CT, XRF, SEM-EDS, DSC, TGA, FTIR, etc.)
Excellent problem-solving, communication, and documentation skills

About the Company

Tesla

Makes electric cars, robotaxis and grid batteries

Tesla makes electric cars and batteries that store power for homes and utilities, and it develops self-driving software and humanoid robots. In 2023, its Model Y became the first electric vehicle to rank as the world's best-selling car. Buyers order the Model 3 sedan, Model Y SUV, or Cybertruck pickup directly from Tesla instead of through dealers, and they charge on its Supercharger fast-charging network. It also sells Megapack and Powerwall batteries, runs a robotaxi service, and charges drivers a monthly fee for self-driving software that still needs their supervision. Tesla was founded in 2003, with Elon Musk as its lead early investor and a recognized co-founder, and it is based in Austin, Texas.
