Company Overview

Mainspring Energy is revolutionizing power generation with the world’s most flexible and adaptable local power generation technology, the Mainspring Linear Generator. Commercial, industrial, and utility leaders are choosing Mainspring over traditional options like engines, turbines, and fuel cells to quickly and reliably deliver local power for EV charging, commercial facilities, data centers, and grid‑scale operations.

The Mainspring Linear Generator is fuel flexible, ramps up and down to meet demand, and utilizes a flameless reaction with near‑zero NOx emissions. Backed by top‑tier investors including Khosla Ventures, Bill Gates, American Electric Power, Lightrock, and General Catalyst, Mainspring designs, manufactures, and delivers its products to customers across the U.S. today, and we’re quickly scaling for international expansion.

Inspired by our vision of the affordable, reliable, net‑zero carbon grid, Mainspring is rapidly expanding within the $816B global electricity equipment market, and we’re hiring the best talent to meet growing customer demand around the globe. We welcome a broad range of backgrounds, experiences, and talents to bring fresh perspectives and ongoing innovation to our customers.

We are looking to build relationships with people who share our values:

• Pragmatic Optimism: Building a new category of world‑class power generation requires the optimism of ambition and creativity, balanced with practicality to solve problems efficiently. The challenges that arise are opportunities for growth.
• Excellence without Ego: We bring expertise and commitment to creating the best customer experience, from sales to deployment and service, just as we apply deep technical rigor to building and delivering world‑class products. We strive for excellence and behave as leaders with the humility to acknowledge our challenges, both collectively and as individual contributors.
• Proactive Collaboration: The integration and cross‑disciplinary nature of Mainspring’s business requires intentionally seeking out others who bring different skills, perspectives, and priorities. Our culture of inclusion and respect extends beyond our team to interactions with our partners and customers.

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 is a plus
