Senior Mechanical Design Engineer - Electromechanical

Mainspring Energy•Menlo Park, CA

1d•$132,000 - $156,000•Onsite

About The Position

Mainspring is seeking Senior 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.

Requirements

Degree: BS or MS in Mechanical Engineering or a similar engineering field from an accredited institution. Experience and degree will determine the level, with the following minimum requirements: Senior: BS + 6 years or MS + 5 years
Proven experience taking ownership of electrical enclosure and/or cable design, from initial design to launch and managing cross-functional teams
Strong 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
Extensive experience in SolidWorks and PDM (or a similar CAD version control system). Experience with CFD, FEA, and programs like SolidWorks Flow Simulation or Ansys is a plus
Demonstrated ability to manage complex technical decisions, influence the direction of designs, and coordinate with teams to achieve successful outcomes
Passion for creating innovative and cost-effective solutions to enable the large-scale deployment of zero-carbon energy technologies

Responsibilities

Lead brainstorming and technical review sessions to develop innovative solutions that enhance the performance and cost-efficiency of the Linear Generator and electrical subsystems
Take full ownership of the design, optimization, and execution of key 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
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
