Senior Cloud Software Engineer

Mainspring Energy•Menlo Park, CA

About The Position

Mainspring Energy is reinventing distributed power generation with our Linear Generator — a fuel-flexible, ultra-low emissions platform delivering resilient, on-site power for commercial, industrial, and utility customers. Now we’re scaling our fleet. We’re looking for the right software engineers to own the cloud-to-device software ecosystem that monitors, manages and optimizes our distributed energy assets. This is a rare opportunity to unify cloud, data, and embedded device software under one technical vision — and scale a platform that directly enables the energy transition. This is industrial-grade, uptime-critical, hardware-connected software. You will be part of the team designing and building systems that ingest and process real-time telemetry from thousands of generators at high speed, enable secure monitoring, diagnostics, and control of remote devices at scale, and build infrastructure to enable updating software on remote embedded devices. When our software works, customers stay powered. When it doesn’t, the stakes are real.
