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. You'll be responsible for designing mechanical components related to high power electronics, including thermal management, harnessing, enclosures, structures, and reliability while also collaborating closely with electrical, software, and systems engineering teams. 

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.  This is a Summer 2026 position.

Responsibilities Will Include: 

• Execute component-level mechanical design and development of a high-volume, high-power energy conversion product from concept to deployment, including thermal management, structural design, packaging/integration of power electronics, and integration with grid infrastructure
• Act as in integral mechanical engineering team member, 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
• Contribute to a collaborative, fast-paced startup culture, where every team member plays a crucial role in achieving company milestones 

Desired Qualifications: 

• Currently enrolled in a degree program for BS or MS in Mechanical Engineering or a related field
• 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.)
• Proficiency in CAD (e.g., SolidWorks) 
• Some basic experience in analysis tools (CFD, FEA, etc.) preferred.
• 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 cross-functional team members 

Physical Requirements:  

• Ability to perform the essential job functions consistent safely and successfully with the ADA, FMLA and other federal, state and local standards, including meeting qualitative and/or quantitative productivity standards.
