About Redwood Materials

Redwood Materials was founded in 2017 by JB Straubel, co-founder and former CTO

of Tesla, on a simple but radical idea: the critical minerals powering the

energy transition already exist. They just need to come back. Today Redwood is the largest lithium-ion battery recycler in North America — recovering, refining, and redeploying critical minerals from end-of-life batteries back into the supply chain. On the energy side, Redwood has deployed the largest second-life battery project in the world, delivering power to AI data centers in months rather than years using proprietary energy architecture engineered entirely in-house. The company is profitable, the market it operates in is projected to grow 20 to 50 times over the next decade, and Redwood is the only company with the supply chain, the technology, and the operational scale to lead it.

Mechanical Engineer, Energy Storage

You will be an early member of a new engineering team, taking a hands-on role in the design, development, and integration of a new high-power electromechanical product line at Redwood. This position starts as a senior individual contributor, where you'll be responsible for designing critical mechanical components and systems related to high power electronics, including thermal management, harnessing, enclosures, structures, and reliability while also collaborating closely with electrical, software, and systems engineering teams. As the product builds momentum, you will be instrumental in building and leading a mechanical engineering team, setting the foundation for scaling our product into high volume manufacturing.

The ideal candidate is highly self-driven, adaptable to a startup environment, and eager to take on both technical and leadership challenges. You’re a leader and a doer, excited about working in a dynamic, fast-paced setting, and want to shape the mechanical engineering function within a new department at Redwood.

If necessary, we will adjust the job level to suit your experience and responsibilities.

Responsibilities will include

Lead and execute the mechanical design and development of a high-volume, high-power energy conversion product from concept to deployment, including thermal management, authoring requirements, structural design, packaging/integration of power electronics, and integration with grid infrastructure
Act as the primary mechanical engineering expert, driving innovation and solving technical challenges at a large scale
Perform mechanical analysis (CFD, FEA, thermal, etc.) to validate designs and ensure performance under real-world conditions
Collaborate with electrical and systems engineers to ensure seamless integration of mechanical systems into the overall system architecture
Select materials and components, working closely with suppliers and vendors to ensure cost-effective, high-quality solutions
Be a hands-on engineering manager, accountable for project goals and timelines
Take a leadership role in recruiting, mentoring, and managing a high-performance mechanical engineering team
Contribute to a collaborative, fast-paced startup culture, where every team member plays a crucial role in achieving company milestones

Desired Qualifications

BS or MS in Mechanical Engineering or a related field
1-3 years of experience in mechanical engineering, with a strong focus in power conversion or energy storage products, ideally for mass production
An understanding of the relationship between high voltage electronics and the mechanical systems that support and surround them (e.g. insulation systems and thermal systems)
Proven track record as a senior mechanical engineer, with hands-on design, prototyping, and launch experience in medium-to-high volume production (10,000 units/yr or higher)
Proficiency in CAD (e.g., SolidWorks) and analysis tools (CFD, FEA, etc.)
Experience developing tools, infrastructure and design practices for a growing team
Self-motivated, with the ability to manage your work in a startup environment, balancing multiple priorities and deadlines
Excellent communication and interpersonal skills, capable of building relationships with all levels of the organization and presenting to internal and external executives
Passion for sustainability and making the world a better place!
