Mechanical Engineer - Electromechanical

Mainspring is seeking Mechanical Design Engineers with a focus on designing electrical enclosures and cables while improving functionality and system-level performance. In this role, you will lead projects from setting requirements, designing, conducting cross functional reviews, coordinating testing and release to ensure that key electrical subsystems meet challenging technical requirements with a potential for direct reports. Ideal candidates will have a strong combination of technical expertise and the drive to solve complex problems in a collaborative environment.

Responsibilities

Lead projects from setting requirements, designing, conducting cross-functional reviews, coordinating testing and release; Involved in brainstorming and technical review sessions to develop innovative solutions that enhance the performance and cost-efficiency of the Linear Generator and electrical subsystems; Ownership of design, optimization, and execution of electrical hardware, balancing cost reduction, safety improvements, and system-level reliability; 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; Development of electrical hardware, including requirements development, prototyping, testing, iteration, and tooling, ensuring project milestones are met and resources are allocated effectively

Requirements

BS or MS in Mechanical Engineering or a similar engineering field from an accredited institution; Senior: BS + 3 years or MS + 2 years; Experience designing electrical enclosure and/or cable design; Expertise in sheet metal design for medium-volume production, electrical component specification, mechanical design for electrical systems, and design-for-manufacturability challenges; A solid understanding of electrical engineering principles and thermal modeling, and the ability to integrate them effectively into larger system designs; Experience in SolidWorks and PDM (or a similar CAD version control system); Passion for creating innovative and cost-effective solutions to enable the large-scale deployment of zero-carbon energy technologies

Nice to have
