Senior Buyer / NPI Buyer Electronics
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. As R&D/NPI Buyer, Electrical, you are the primary supply chain point of contact for the Engineering team — the person engineers come to for parts on the bench, prototype builds, and new suppliers stand up fast. You’ll own tactical purchasing for R&D and prototype builds and carry those parts through the transition into production as programs move from NPI to manufacturing. The work mixes structured projects (supplier/part qualification, RFQs, EC cut-in planning) with a live queue of ad-hoc requests. You’ll sit on the SC PM & Cost Engineering team within Strategic Sourcing.
