$13,149 more — $193,149 — moves this role to Level III and 3 lottery entries. That figure is inside the range the employer already advertised.

Based on the DOL prevailing wage for this occupation and worksite, a base salary of $193,149 would place this position at wage Level III. That figure is within the posted range, and I'd like to target it. This role classifies under "Software Developers" for prevailing-wage purposes.

Company info

  • Peak Energy is the first American venture to advance globally proven sodium-ion battery systems as the storage standard for the new era of renewable energy on a resilient grid.
  • Sodium-ion is cheap, readily available, and safe - making it the leading contender in a rapidly evolving market.
  • Our leadership team is powered by decades of expertise in scaling gigawatt-level innovation at world-class companies such as Tesla, Northvolt, Apple, Powin, Enovix, Zipline, Solid Power, SunPower, and Fluence.
  • We are backed by strategic investment and product partners including TDK Ventures, Eclipse Ventures, and GM Ventures.
  • We recently announced America's first sodium-ion grid storage factory in Sacramento with production starting Q1 2027, and over $1B in signed customer commitments including Jupiter Power and Energy Vault.
  • About the Role - Full-Stack Software Engineer
  • Peak Energy is looking for a Full-Stack Software Engineer to help scale the software backbone behind our grid-scale battery storage systems.
  • Our platform ingests, processes, and surfaces operational data from batteries deployed in the field - turning raw telemetry into the metrics our customers, operations team, and engineering team rely on every day.
  • As Peak grows from pilot deployments to gigawatt-scale production in Sacramento, this platform becomes mission-critical.
  • This is a hands-on, full-stack role that spans application code, cloud infrastructure, and the tooling that ties it all together.
  • You'll design and build data pipelines that calculate the metrics that define battery performance (round-trip efficiency, availability, cycle tracking), wire our manufacturing environment into that pipeline as we ramp Sacramento production, and own the infrastructure and CI/CD practices that make our software team fast and reliable.
  • You'll join a small software team where individual ownership is real - you'll ship, monitor, and iterate on production systems that customers, operators, and engineers all depend on.
  • This is a great fit for someone who wants to build meaningful infrastructure at a company doing genuinely novel work in energy storage.
  • This role partners closely with ESS Engineering, Manufacturing Engineering, and Product.
  • (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.
  • 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.
  • 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.
  • What You'll Bring (Minimum Qualifications)
  • Strong SQL skills - PostgreSQL, time-series queries, schema design and migrations.
  • Cloud platform experience - Azure preferred; AWS or GCP transferable.
  • Comfort taking ownership of production systems, including monitoring, incident response, and continuous improvement.
