Peak Energy is advancing sodium-ion battery systems as the storage standard for renewable energy grids. The company recently announced America's first sodium-ion grid storage factory in Sacramento with production starting Q1 2027, backed by strategic investors including TDK Ventures, Eclipse Ventures, and GM Ventures, with over $1B in signed customer commitments.
You will join a small software team as a Full-Stack Software Engineer reporting to the CTO within the ESS Engineering department. This is a hands-on role spanning application code, cloud infrastructure, and DevOps tooling. You'll design and build the data pipeline that processes raw telemetry from deployed batteries into production-critical metrics (round-trip efficiency, availability, cycle tracking). As Peak scales from pilot deployments to gigawatt-scale production, you'll wire the manufacturing environment into the pipeline and own the infrastructure and CI/CD practices that enable the software team to move fast and reliably.
Key responsibilities include:
- Design, build, and maintain the post-processing pipeline calculating battery metrics from raw telemetry using Azure Functions, persisting to cloud database for dashboarding and analytics
- Connect manufacturing database to physical devices and cloud pipeline as Sacramento factory scales production
- Maintain and improve real-time data pipeline infrastructure from field sites to cloud, ensuring reliability and low latency across growing fleet
- Design and maintain automated CI/CD pipelines for build, test, and deployment across software stack
- Define and manage cloud resources via Infrastructure as Code (Terraform or equivalent), replacing manual provisioning with repeatable, version-controlled infrastructure
- Partner with ESS Engineering and Manufacturing Engineering to instrument features, surface data to teams, and improve observability
- Own production issues end-to-end—diagnose, fix, and improve systems to prevent recurrence
This role is ideal for someone who wants to build meaningful infrastructure at a company doing genuinely novel work in energy storage, with individual ownership and real impact on production systems customers and operators depend on.
REQUIREMENTS:
Minimum qualifications:
- 4+ years of software engineering experience with meaningful full-stack, backend, or platform work in production
- Strong Python skills (backend data processing, automation, scripting)
- Strong SQL skills (PostgreSQL, time-series queries, schema design and migrations)
- Cloud platform experience (Azure preferred; AWS or GCP transferable)
- Hands-on experience with Infrastructure as Code (Terraform or equivalent)
- Experience designing and maintaining CI/CD pipelines (GitHub Actions, Azure DevOps, or similar)
- Comfort taking ownership of production systems, including monitoring, incident response, and continuous improvement
- Bachelor's degree in Computer Science, Computer Engineering, or related technical field, or equivalent experience
Preferred qualifications:
- 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 Series B/C hardware or industrial startup
- Experience partnering with hardware, firmware, or embedded teams
