Engineering Internship / Co-Op

About Brelle

Brelle is a venture-backed technology company building the next generation of energy and powertrain systems for demanding machines. Our team brings deep expertise in high-performance engineering, electrification, and advanced manufacturing. Brelle develops frontier technology that pushes what’s possible in electrified performance, for supercars and superbikes, working alongside leading high-performance brands across the U.S. and Europe. Our innovations are built on a novel pack architecture, a full-stack software platform, and an advanced approach to automated production.

Engineers at Brelle operate like nimble, cross-functional, and highly technical Skunkworks teams. Engineers are encouraged to explore new concepts and materials, move quickly from concept to prototype, and have significant autonomy.

The Opportunity

Brelle welcomes applications from students interested in internship and co-op opportunities across engineering and related technical disciplines. This posting is a centralized opportunity to connect with promising early-career talent for placements aligned with evolving project and team needs. As an intern or co-op student, you’ll apply technical knowledge to real engineering challenges, contribute to the development of next-generation energy and powertrain systems, and learn alongside a team at the forefront of electrified performance. We seek curious, driven individuals who enjoy solving difficult problems, take ownership, and thrive in a fast-moving, hands-on engineering environment.

Areas of Opportunity

Opportunities may span areas such as:

• Mechanical Engineering & CAD:
• Create and update 3D models, assemblies, detailed 2D engineering drawings, and mechanical designs.
• Support design iteration and development.
• Electrical Engineering:
• Support electrical design, component integration, wiring and harnesses, and related electrical systems.
• Systems Engineering:
• Contribute to system architecture, requirements development, component integration, and cross-functional engineering coordination.
• Prototyping, Testing & Validation:
• Support prototype builds, test setup and execution, data collection, troubleshooting, and design validation.
• Manufacturing & Production Engineering:
• Contribute to design for manufacturability, assembly processes, tooling, production methods, and process improvement.
• Software & Controls:
• Support embedded systems, controls, data analysis, automation, and software development for energy and powertrain systems.

Specific responsibilities will depend on the placement, your skills, and the projects you support.

What You'll Bring

• Current enrollment in a college or university program in engineering or a related technical discipline.
• Strong technical fundamentals and a genuine interest in building, testing, and improving real-world systems.
• A hands-on, analytical approach to solving challenging problems, with a willingness to question assumptions and explore better solutions.
• Initiative, attention to detail, and a willingness to take ownership of your work and follow through on commitments.
• The ability to collaborate across disciplines, communicate openly, and consider the broader team’s needs while making meaningful progress independently.
• The ability to learn quickly, adapt to changing priorities, and contribute in a fast-moving environment.

Relevant technical projects, personal builds, research, laboratory experience, CAD proficiency, programming experience, or previous internships are valuable.
