Job Overview

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.

Core Responsibilities

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

Qualifications

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 + 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). Experience with CFD, FEA, and programs like SolidWorks Flow Simulation or Ansys is a plus

Passion for creating innovative and cost-effective solutions to enable the large-scale deployment of zero-carbon energy technologies
