Mechanical Design Engineer (Senior to Staff) – Generator Hardware

(Hybrid location) 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.
