Cloud Software Engineer

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

• 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 Google Cloud Platform (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
