Company Overview

Driven by our vision of the affordable, reliable, net-zero carbon grid of the future, Mainspring has developed a new category of power generation — the linear generator — that delivers local, scalable, and fuel-flexible power to help accelerate the transition to the net-zero carbon grid.

The unique combination of attributes offered by Mainspring’s linear generator enables applications on both the commercial and utility sides of the meter for the $816B global electricity equipment market. We serve a wide range of Fortune 500 customers across markets and industries as well as top-tier utilities and other gridside providers.

We are looking to build relationships with people who share our values:

• Pragmatic Optimism. Building a new category of world-class power generation requires the optimism of ambition and creativity, balanced with practicality to solve problems efficiently. The challenges that arise are opportunities for growth.
• Excellence without Ego. We bring expertise and commitment to creating the best customer experience, from sales to deployment and service, just as we apply deep technical rigor to building and delivering world-class products. We strive for excellence and behave as leaders with the humility to acknowledge our challenges, both collectively and as individual contributors.
• Proactive Collaboration. The integration and cross-disciplinary nature of Mainspring’s business requires intentionally seeking out others who bring different skills, perspectives, and priorities. Our culture of inclusion and respect extends beyond our team to interactions with our partners and customers.

Mainspring is based in Menlo Park and has partnered with top-tier investors and utilities such as Khosla Ventures, Bill Gates, NextEra, and American Electric Power. More information can be found at www.mainspringenergy.com.

Responsibilities

One core innovation in the Linear Generator is the use of a piston and ring system without liquid lubricant, which dramatically reduces emissions and O&M costs. This person will work on the challenging design of these solid lubricant systems, involving complex 3D shapes with sliding seals, high pressure and temperature, materials optimization, with complex fluid dynamics, heat transfer and structural mechanics. This person needs to be a fast learner, who can design parts and do hands-on work in the lab to analyze performance and failure modes.

• Design of complex moving parts in the piston and ring system of the Linear Generator, from originating creative ideas, executing the design and build, testing and then evaluating performance
• Support the Root Cause Investigation efforts of subsystems that involve complex thermal/structural/materials/fluids interactions to identify and address underlying mechanical component failures with a particular focus to rings and pistons.
• Manage and resolve quality notices related to vendor supplied parts or internal assembly steps associated with the sub system of pistons and rings.

Qualifications

• Bachelors with at least two years’ experience or Masters In Mechanical Engineering or equivalent (also open to recent B.S. graduates that have had experience in Baja SAE, Formula SAE, HPV ASME or similar programs)
• Self-starter who thrives in a fast-paced dynamic environment and can optimize solutions across different teams.
• Fluent in SolidWorks or comparable CAD package, with a solid understanding of structural mechanics, including structural FEA
• Solid physical understanding in several of the following fields is a plus: Failure Criterias (Von Mises, Tresca, Coulomb-Mohr), Fatigue (Goodman, Soderberg), Stress Relaxation and Creep.
• Ability to generate 2D drawings for manufacturing, experience utilizing GD&T is preferred

Preferred Qualifications

• Fluent in Data Science and Python Programming: 3-month Data Science bootcamp or equivalent experience: Ability to generate regression models to fit to data with multiple predictors (Weibull, Linear, other)

The Bay Area salary for this role is $115k-$125k base + pre-IPO stock options + benefits. This position is on-site in Menlo Park, CA. The salary will be adjusted based on the experience of the employee.
