2026 Fall Engineering Intern

About the role

The role is an Engineering Intern position at Estes Energy, located on-site in San Francisco. The term is from September to December, 2026, with flexible dates.

Responsibilities

• Contribute to the design, build, and test of components or subsystems within our power systems (mechanical, electrical, controls, battery, manufacturing, or systems engineering — depending on your focus)
• Develop and run experiments to test hypotheses, then turn data into decisions
• Build tools, models, fixtures, or analyses that help the team move faster
• Document your work clearly and present findings to the team
• Take ownership of a defined project and drive it to a measurable result by the end of your term

Requirements

• Pursuing a degree in Mechanical, Electrical, Chemical, Materials, Manufacturing, Systems, Material Science, Metallurgy or a related engineering field (or equivalent hands-on experience)
• Curious and rigorous — you ask "why," challenge assumptions, and get to the root of a problem before building up
• Comfortable with experimentation and data; you care about data integrity
• Able to take ownership, work independently, and collaborate directly and honestly
• Bias toward making things: hands-on project, lab, internship, research, or build-team experience is a plus
