Staff Mechanical Design Engineer - Electromechanical

Job description

### About Mainspring Mainspring Energy manufactures and delivers fuel-flexible, low-emissions local power solutions that rapidly add new capacity and deliver reliable, affordable, and sustainable electric power. The company began commercial shipments of its Mainspring Linear Generators in 2020 and today has hundreds of megawatts in advanced development and field operations for leading Fortune 500 companies, data centers, and utilities. Mainspring also partners with global energy leaders including AEP, NextEra Energy Resources, Schneider Electric, and more. The [core values](https://www.mainspringenergy.com/company) that ground our work, guide our decisions, and connect us together: - Pragmatic Optimism - Excellence without Ego - Proactive Collaboration ### Job Overview Mainspring is seeking Staff 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 - 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 ### 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 + 10 years or MS + 8 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
