Mechanical Engineer - Thermal / Fluids Hardware Design

Mainspring Energy•Menlo Park, CA

1d•$119,000 - $165,000•Onsite

About The Position

Mainspring Energy is seeking a mid-level Mechanical Engineer focused on designing hardware requiring thermal and fluids analysis. The role designs hardware for air and liquid handling systems and develops new concepts while managing existing concepts through development, deployment, and manufacturing. Engineers in this role solve challenging cross-functional problems using computational analysis, hands-on engineering, and teamwork. The position develops and optimizes thermal subsystems for Mainspring’s Linear Generator to reduce cost, improve performance, and deliver high reliability. It also contributes to projects in other subsystems, works with reliability and test teams to validate systems and components, and collaborates with manufacturing engineering, NPI, and external suppliers to deploy designs into production. The position is onsite at Mainspring’s Menlo Park headquarters. The salary range is $119,000–$165,000 per year, with pre-IPO company equity through Restricted Stock Units (RSUs) and benefits.

Requirements

Bachelor’s degree in Mechanical Engineering or a similar engineering field from an accredited institution and at least 3 years of relevant industry experience, or a master’s degree and at least 2 years of relevant industry experience.
Direct experience designing air or liquid handling systems, with demonstrated engineering fundamentals in thermo-fluid system design.
Fluency in SolidWorks or a comparable CAD package.
Experience with finite element analysis (structural, thermal, or fluids).
Familiarity with thermal systems design simulation tools.
Experience developing test plans and analyzing data for benchtop-to-product-scale tests to validate new design concepts.
Experience working with suppliers to develop and qualify new components.
Experience with manufacturing processes such as sheet metal forming, machining, and plastics molding and forming.
Attention to detail and the ability to generate and review design documentation, bills of materials, work instructions, test plans, and reports.
Ability to deliver functional product designs in a rapid development environment.
Interest in developing creative and cost-effective solutions to enable large-scale deployment of zero-carbon energy technology.

Nice To Haves

Experience using a Product Lifecycle Management (PLM) system or similar CAD version-control system.
Experience utilizing GD&T.
Experience with a full design lifecycle from concept through manufacturing support.

Responsibilities

Develop and optimize key thermal subsystems of the Linear Generator to reduce cost, improve performance, and deliver high reliability.
Contribute to projects within thermal subsystems and other subsystems.
Work with reliability and test teams to validate systems and components through rapid learning cycles for deployment in the next generation of Linear Generators.
Participate in brainstorming to develop novel ways to improve all aspects of the Linear Generator.
Collaborate with manufacturing engineering, NPI, and external suppliers to rapidly deploy new designs into production.
