About Brelle
“Energy for what moves us” defines our mission at Brelle. Based in California, Brelle engineers a modular energy platform for the world’s most demanding machines – supercars, superbikes and aerial systems. Our innovations are built on a novel battery pack architecture, a full-stack software platform, and automated manufacturing. Joining the team means working on making electric vehicles—on the road and racetrack—lighter, more engaging and safer.
About the Role
As Director of Energy Systems, you will own Brelle's battery systems — the architecture decisions, the engineering team, and the path from concept to production. This means leading module and pack development across mechanical, electrical, thermal, and structural domains, while building the team that makes it all possible.
What You’ll Own
- Battery module and pack architecture: cell integration, thermal management, HV safety, electromechanical systems, and structural design
- Architecture trade-offs across energy density, weight, thermal performance, cost, safety, and manufacturability
- Engineering processes, design standards, and review cadences — embedding safety and quality into rapid iteration
- DFMEA, DVP&R, design release, and certification/homologation
- Define and maintain the battery systems technology charter, aligning technical investments with Brelle’s product roadmap
- Technical program management: milestones, dependencies, and delivery of hardware and analysis
- Energy systems budget and technology roadmap
Team & Leadership
- Build and scale a world-class engineering team by attracting, developing, and retaining exceptional talent who thrive in a high-performance environment
- Foster a culture of technical excellence, intellectual honesty, and relentless improvement—where engineers are empowered to challenge assumptions and pursue novel solutions at rapid pace
Preferred Qualifications
- 10+ years of experience in battery pack/module design or powertrain development
- BS or MS in Mechanical Engineering, Electrical Engineering, or a related field
- Deep expertise across battery system architecture: cell integration, thermal management, HV safety, and structural design
- Advanced CAD proficiency with the ability to engage at the design detail level
- Strong understanding of DFM across multiple processes: injection molding, stamping, casting, composites, machining
- Deep knowledge of materials science and advanced manufacturing processes
You Are...
- Fundamentally Curious – You break complex problems down to first principles and are energized by hard problems worth solving at scale
- A Builder of Exceptional Teams – You attract world-class talent, set exceptionally high standards, and create an environment where engineers do the best work of their careers
- Autonomous and Decisive – You take ownership of ambiguity, make informed calls, and execute with conviction. You empower your team to do the same, creating a culture of accountability and bias for action
