Job Overview

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 architect to own the cloud-to-field software ecosystem that powers, monitors, 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.

Responsibilities

Ingest and process real-time telemetry from thousands of generators at high speed
Enable secure monitoring, diagnostics, and control of remote devices at scale
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

Qualifications

You are a systems thinker who understands that software decisions impact physical infrastructure.
7+ years in software engineering on production systems, including team technical leadership
Experience with device-to-cloud architectures and telemetry pipelines
Experience with AWS, GCP, or Azure
Experience in distributed systems and cloud infrastructure
A reliability-first mindset — 99% uptime isn’t good enough
Experience in Industrial IoT, energy systems, industrial automation, or fleet-scale device platforms a plus
