Full-Stack Software Engineer

Peak Energy is seeking a Full-Stack Software Engineer to build and scale the software platform supporting its grid-scale battery storage systems. The role focuses on battery data pipelines and metrics, manufacturing data integration, cloud infrastructure, CI/CD, and production system reliability.

Responsibilities

• Design, build, and maintain the post-processing pipeline that calculates production-critical battery metrics — round-trip efficiency, availability, cycle tracking — from raw telemetry, using Azure Functions and persisting to our cloud database for dashboarding and analytics
• Connect our manufacturing database to physical devices and the cloud pipeline as Peak scales production at our Sacramento factory, enabling data-driven manufacturing at gigawatt scale
• Maintain and improve the real-time data pipeline infrastructure from physical sites in the field to our cloud database, ensuring reliability and low latency across a growing fleet of deployed batteries
• Design and maintain automated CI/CD pipelines for build, test, and deployment across our software stack, reducing time from commit to production
• Define and manage cloud resources via Infrastructure as Code (Terraform or equivalent), replacing manual provisioning with repeatable, version-controlled infrastructure that scales as our deployment footprint grows
• Partner with ESS Engineering and Manufacturing Engineering to instrument new features, surface the right data to the right teams, and improve observability across the platform
• Own production issues end-to-end when they arise — diagnose, fix, and improve the systems to prevent recurrence

Preferred

• Prior experience with battery systems, energy storage, EV, IoT, or industrial telemetry platforms
• Experience with real-time streaming data infrastructure — Kafka, Azure Event Hubs, Kinesis, or similar
• Familiarity with observability and monitoring platforms — Datadog, Grafana, Application Insights
• Docker and container orchestration experience
• Prior experience at a Series B/C hardware or industrial startup — comfort with the pace and building process where none exists
• Experience partnering with hardware, firmware, or embedded teams
