Collaborate with reliability and test teams to validate systems and components, ensuring fast iteration cycles and incorporating feedback to drive the next-generation deployment of the Linear Generator
Collaborate cross-functionally with electrical engineering, manufacturing engineering, NPI, and external suppliers to deploy new designs into production, ensuring all systems meet the necessary performance and manufacturability requirements
Lead the development cycle of electrical hardware, including requirements development, prototyping, testing, iteration, and tooling, ensuring project milestones are met and resources are allocated effectively
Mentor and support junior engineers, guiding them through technical challenges, offering advice on design strategies, and helping to develop their skills while working towards project goals
