Engineering Internship / Co-Op

Brelle•Los Alamitos, CA

About The Position

Brelle is a California-based, venture-backed technology company developing energy and powertrain systems for high-performance vehicles and aircraft. It builds on a novel battery-pack architecture, a full-stack software platform, and automated production methods. Brelle welcomes applications from students seeking internship or co-op opportunities in engineering and related technical disciplines. Students may apply their technical knowledge to real engineering challenges, contribute to next-generation energy and powertrain systems, and learn alongside a team working in electrified performance. Placements depend on the candidate’s background and interests and on current or anticipated business needs; not every area will have an active opening at all times. Potential areas include mechanical engineering and CAD, electrical engineering, systems engineering, prototyping, testing and validation, manufacturing and production engineering, and software and controls. Specific responsibilities, placement duration, start date, and schedule will depend on the placement, the candidate’s academic program, and business needs. Candidates are asked to indicate their field of study, technical interests, availability, and preferred placement duration when applying. These are paid positions, with compensation determined by the specific placement, relevant experience, and other applicable factors.

Requirements

Currently enrolled in a college or university program in engineering or a related technical discipline.
Strong technical fundamentals and genuine interest in building, testing, and improving real-world systems.
