About Mainspring

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.

The core values that ground our work, guide our decisions, and connect us together:

• Pragmatic Optimism
• Excellence without Ego
• Proactive Collaboration

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 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

• 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 development on production systems, including team technical leadership 

• Experience with device-to-cloud architectures, IoT and distributed telemetry pipelines

• Experience with GCP (preferred) or AWS

• 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

This position is onsite at our Menlo Park HQ . The salary will be adjusted to reflect local market conditions based on employee location as well as the experience of the employee. Along with the base salary, Mainspring offers pre-IPO stock options + benefits.

Does your experience not meet all of our posted requirements? Studies have shown that some people are less likely to apply to positions unless they meet every listed requirement. At Mainspring, we are committed to building a diverse, inclusive, flexible, and collaborative environment, so if you want to help us transition the world to clean and affordable electricity, and don’t meet all posted requirements for a particular role, we’d still love to hear from you. Mainspring can sometimes be flexible enough to shift responsibilities for the right person, or otherwise identify open or upcoming roles that may better fit your professional background.
