Director of Software Engineering

Director of Software Engineering - Lead the Digital Backbone of Distributed Energy

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 leader 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, DevOps, and fleet software under one technical vision — and scale a platform that directly enables the energy transition.

This is not a SaaS role.

This is industrial-grade, uptime-critical, hardware-connected software.

You will lead the team building systems that:

• Ingest and process real-time telemetry from thousands of generators
• Enable secure remote monitoring, diagnostics, and control
• Power predictive maintenance and fleet analytics
• Maintain a scalable “single source of truth” data platform
• Govern DevSecOps and release management across R&D, manufacturing, and field deployments
• 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.
• 10+ years in software engineering, including 5+ years in senior leadership
• Experience in Industrial IoT, energy systems, industrial automation, or fleet-scale device platforms
• Ownership of device-to-cloud architectures and large telemetry pipelines
• Deep experience with AWS, GCP, or Azure
• Expertise in distributed systems, cloud infrastructure, and data platforms (e.g., Snowflake, Spark)
• Experience leading DevSecOps and secure remote control systems
• A reliability-first mindset — 99% uptime isn’t good enough

Note: 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.
