Staff Cloud Software Engineer

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.
• 12 + 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
