About Brelle
Energy for what moves us.
Brelle is a venture-backed technology company building the next generation of energy and powertrain systems for the world’s most demanding machines. Our team comes from companies like Rivian, SpaceX, and McLaren, bringing deep expertise in high-performance engineering, electrification, and advanced manufacturing.
Brelle develops frontier technology that pushes what’s possible in electrified performance. Based in California, we develop next-generation energy and powertrain technology 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. Joining Brelle means working on technology that makes the world’s most demanding vehicles and aircraft lighter, safer, more engaging, and capable of charging in minutes.
Our engineering teams operate like small Skunkworks teams: nimble, cross-functional, and highly technical. Engineers are encouraged to explore new concepts and materials, move quickly from concept to prototype, and have significant autonomy to develop, validate, and release their work across programs.
We’re building something ambitious in a highly competitive market, and the bar is high. We need people who are exceptional at what they do, take real ownership, and are willing to do what the moment requires.
About the Role
As Senior Manager for Battery Design Engineering, you will be a hands-on contributor to Brelle’s battery systems – working through architecture decisions and staying close to the engineering details as module and pack development moves from concept to production across mechanical, electrical, thermal, and safety domains. You’ll also lead a small engineering team, acting as an approachable, guiding mentor who works alongside them rather than directing from a distance.
What You'll Do
Design and develop battery module and pack architecture — cell integration, thermal management, HV safety, electromechanical systems, and structural design
Work through architecture trade-offs across energy density, weight, thermal performance, cost, safety, and manufacturability, and drive them to a decision
Run design reviews and engineering processes — DFMEA, DVP&R, design release, and certification/homologation — with a hands-on role in the actual analysis and documentation, not just process oversight
Get hands-on with hardware and analysis — prototyping, testing, debugging, and iterating alongside the team
Coordinate milestones and dependencies across mechanical, electrical, thermal, and structural workstreams to keep delivery on track
Lead and grow a small battery engineering team — hiring and developing talented engineers, and staying closely involved in their day-to-day work
What We're Looking For
Deep expertise across battery system architecture: cell integration, thermal management, HV safety, and structural design
Strong understanding of DFM across multiple processes: injection molding, stamping, casting, composites, machining
How We Work
Understand the Problem
We take the time to understand what we're actually solving before jumping to the obvious answer.
Own What Needs to Happen
We take responsibility for outcomes, not just our individual tasks. If something needs to happen, we figure out how to make it happen.
Optimize for the Team
We make decisions with the broader team and company in mind, sharing information and helping each other move faster.
Refuse the Obvious Answer
We challenge assumptions, explore better approaches, and don't accept "that's how it's always been done."
Keep Your Word
We do what we say we'll do. We communicate early when something changes and hold ourselves accountable to our commitments.
Compensation & Benefits
Base Salary: $170,000 - $200,000
Meaningful equity participation through Brelle's Employee Incentive Plan.
Build something exceptional. Own your work. See it move.
