Internship, Cell Materials Engineer, Cell Engineering (Fall 2025)

Consider before submitting an application:

This position is expected to start around August or September 2025 and continue through the Fall term (ending approximately December 2025) or continuing into Winter/Spring 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.

Location: Boulder, CO

Your application for the Cell Engineer, Cell Engineering Internship will be considered across all opportunities for the teams listed below:

Process Engineering

• The Process Engineering team takes on difficult challenges in processing and materials science to realize the full potential of next generation energy storage solutions, ensuring Tesla remains a leader in cell technology and electrode fabrication. The intern on this team will document observations and present findings to technical audience on routine basis. They will support the boulder R&D team through fabrication of small scale electrode coatings.

Materials Engineering

• The Fundamentals Advanced Materials team support multiple, high-impact projects which will involve implementing existing techniques, developing new techniques, and analyzing existing data to characterize battery materials, determine degradation mechanisms, and optimize cell performance at Tesla. This intern will be responsible for supporting the development cell test plans to characterize initial cell performance, lifetime behavior, reliability, and identify critical failures and degradation modes. In addition, this candidate will help plan test resources, track test progress and analyze/report testing results.

• Currently pursuing a degree in Engineering, preferably in Chemistry, Chemical Engineering, Materials Science, or a related field

• Experience with electrochemical and mechanical evaluation of battery electrode analysis techniques (Arbin, Maccor, Biologic, or similar)

• Familiarity with degradation mechanisms of batteries and battery materials

• Experience using MATLAB/Simulink, Python, or similar data analysis tool

• Knowledge of lithium-ion battery technology and electrochemistry

• First-principal physics understanding of electrical and mechanical systems, power delivery, energy storage and transformation, and thermo-fluids engineering
