About The Position

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 that ground our work, guide our decisions, and connect us together: Pragmatic Optimism, Excellence without Ego, Proactive Collaboration. Mainspring Energy is growing rapidly and has begun to manufacture its Linear Generators in volume, and reliability is a crucial element to the success of the product. The reliability team is responsible for evaluating design risks, and implementing tests and analyses to quantify and reduce risk to an acceptable level for the target market. Reliability engineers will use tools such as FMEA, HALT and root-cause analysis on a regular basis. The successful candidate is highly organized and communicative, and will thrive in a nimble fast-paced environment that includes product engineering, R&D and manufacturing.
