Internship, Reliability Engineer, Cell Engineering (Winter/Spring 2026)

Consider before submitting an application:

This position is expected to start around January 2026 and continue through the Winter/Spring term (ending approximately May 2026) or continuing into Summer 2026 if available and there is an opportunity to do so. We ask for a minimum of 12 weeks, full-time and on-site, for most internships. Our internship program is for students who are actively enrolled in an academic program. Recent graduates seeking employment after graduation and not returning to school should apply for full-time positions, not internships.

International Students: If your work authorization is through CPT, please consult your school on your ability to work 40 hours per week before applying. You must be able to work 40 hours per week on-site. Many students will be limited to part-time during the academic year.

About the Team

Battery Cells are the common denominator for every Tesla product. Our product requirements necessitate ground-up cell architectures with state-of-the-art performance, manufactured at volumes that are orders of magnitude higher than the products they power. We are looking for passionate and self-motivated candidates to join us in our fast-paced and exciting mission. Our team works with Engineering groups across various disciplines, requiring strong communication skills and a team-first mentality. You will work alongside seasoned industry experts, high aptitude recent graduates, and people from every stage in between. We look for anyone with an exceptional ability to solve problems in both individual and team settings.

Our team develops and performs cutting edge and industry leading qualification techniques of battery cells that influence the future direction of Tesla products. We are looking for an Engineering Intern who can independently lead technical projects, analyze and summarize large amounts of data, and use critical engineering judgement to plan, execute, and report.

• Leverage the vast amounts of data generated throughout the cell qualification process to help Tesla design and produce safer, lower-cost, and high-performance cells.

• Analyze and visualize data to identify trends and risks in cell programs

• Create tools for rapid analysis of datasets and characterization techniques

• Aid in designing tests and analyzing data to understand fundamental battery degradation modes

• Currently pursuing a degree in Data Science, Computer Science, Reliability Engineering, Mechanical Engineering, Materials Science or a related field

• Understanding of Design for Reliability and Design of Experiments

• Proficient in Python data analysis and visualization

• Proficiency in statistical modeling and scripting, knowledge of Design of Experiments, DFMEA and Design for Reliability, experience collaborating with design, manufacturing, and testing teams, proficiency in data analysis

• Familiarity with reliability software tools and Weibull analysis, knowledge of mechanical and electrochemical battery cell failure modes, Data Science, Data Engineering

• Knowledge on lithium-ion cell life modeling and electrochemical mechanism is a plus but not required
