About the company:

Redwood Materials is an American clean energy company headquartered in Sparks, Nevada, focused on securing domestic supplies of critical battery materials and providing large-scale energy storage solutions. The company recycles end-of-life batteries to recover lithium, nickel, cobalt, and copper, creating one of the largest domestic sources of these critical minerals in the United States. Its operations support the broader transition away from reliance on foreign supply chains for materials essential to electric vehicles and energy storage systems. Through its Redwood Energy division, the company designs, integrates, and deploys large-scale energy storage systems for data centers and the national grid, utilizing both new and repurposed batteries to deliver cost-effective solutions. Redwood Materials partners with major automotive, technology, and energy companies including Volkswagen Group of America, Panasonic, GM Ultium Cells, Toyota, BMW, Amazon, Volvo, and Southern Company, reflecting its central role in the emerging domestic battery supply chain. Founded by former Tesla Chief Technology Officer JB Straubel, Redwood Materials was established with the mission of building a circular economy for batteries, reducing waste, lowering the carbon footprint of energy storage, and strengthening American energy independence. The company holds ISO 45001 and ISO 14001 certifications, underscoring its commitment to occupational health, safety, and environmental management standards.

  • Drive architectural studies to explore the cost and performance design space. 
  • Produce component-level sensitivity analysis to allow component owners to make globally optimal cost and performance tradeoffs. 
  • Utilize the models to produce repeatable and dependable results for various stakeholders within the organization to drive product architecture and site-specific deployment decisions. 
  • Parallelize our modeling framework to utilize cloud computing resources to get results faster. 
  • Lead model validation efforts by writing test plans, working with test engineers to execute the test, and using the data to correlate the model. 
  • Effectively communicate modeling results to drive architecture and performance initiatives. 

Desired Qualifications: 

  • An MS or PhD in Mechanical Science, Electrical Engineering, or a related field. Or a BS and 2+ years of related work experience. 
  • Excellent first-principles physics understanding of electrical and mechanical systems, power delivery, energy storage and transformation, and basic thermal mechanics. 
  • Experience collaborating in software projects with multiple contributors. 
  • Hybrid or electric powertrain model development, PV model development, or data analysis in Python or MATLAB/Simulink. 
  • Familiarity with basic controls techniques, such as filters, PID controllers, and system identification. 
  • Experience with optimization techniques. 
  • Demonstrated ability to write clear and testable engineering requirements. 
  • Strong communication and collaboration skills.
