Senior Manager, Software Engineering

Peak Energy is looking for a DevOps Engineer to build and scale the cloud infrastructure, deployment pipelines, and automation systems supporting our grid-scale battery storage technology.

As Peak grows from pilot deployments to gigawatt-scale production, our software infrastructure must scale alongside our products. You'll help establish the foundation that enables our engineering teams to develop, test, and deploy software efficiently and reliably.

This is a hands-on infrastructure engineering role focused on cloud services, Infrastructure as Code, database provisioning, CI/CD pipelines, and deployment automation. You'll build and maintain the systems that connect our development environments, manufacturing operations, and deployed battery systems to the cloud.

You'll work closely with software, test, and manufacturing engineering teams to improve automation, reliability, and scalability across our software infrastructure.
