Cathode Design Engineer

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.

Redwood Materials is currently recruiting a Cathode Design Engineer to join our Cathode R&D team to develop the next generation of cathode active materials (CAM) and their manufacturing processes. This role is at the center of our activities focused on creating a sustainable circular economy for lithium-ion batteries.

As a Cathode Design Engineer, you will play a leading role in the development of new processes for scaling up and manufacturing CAM, including identifying or developing production technologies. These technologies are key to scaling cost-effective processes that meet the high-quality needs of CAM.

The role is based at our McCarran, Nevada location, which includes pilot plant facilities to produce CAM and state-of-the-art analytical and electrochemical capabilities. As a member of the Redwood Materials team, you will be at the center of a rapidly growing company driving to become the world’s largest and most sustainable producer of materials for lithium-ion batteries.

Responsibilities

Conduct design of experiments to gather relevant data to guide scale-up design, inform process parameter tolerances, improve material performance, and reduce production costs

Provide engineering expertise (such as mass and energy balance, flowsheet, and process simulation) to identify, develop, and implement process technologies for the scale-up and production of cathode active materials (CAM)

Interface with equipment suppliers through concept development, system design, detailed design, procurement, installation, and acceptance testing

Support development of the technology roadmap to align with business strategy and customer needs while defining and leading technology projects

Create intellectual property (IP) and collaborate with the legal team to write and file patent applications

Provide technical expertise to commercial and business development teams, senior management, and key stakeholders

Desired Qualifications

Advanced degree (BS or MS) in an engineering or material science discipline

Evidence of exceptional ability, including strong understanding of engineering fundamentals and demonstrated ability to leverage this understanding to solve challenging problems

1–5 years of industrial experience in relevant areas such as process development and scale-up, process engineering, and technology management

Technical expertise in inorganic materials processes including solids handling, hydrometallurgy, calcination, or chemical processing

Familiarity with thermal equipment (dryers or kilns), powder loading, dosing, mixing, conveying, milling equipment, and solid-liquid separation equipment

Ability to perform process design including mass and energy balance calculations, process flow sheet development, and simulation

Excellent data analysis and technical presentation abilities

Ability to manage and prioritize activities in a fast-changing environment

Track record of building trust within internal teams and with external customers

Excellent written and verbal communication skills

A passion for sustainability and clean energy technology

The position is full-time. Compensation will be commensurate with experience.
