About the Company
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 – Sales Engineer
As a Sales Engineer, you’ll own the technical side of Peak’s opportunities from the first customer conversation through contract signature. You’ll work with prospective customers to define the commercial and technical fit for Peak’s battery systems, build the business case, lead preliminary design discussions, and negotiate the technical scope, schedule, and performance terms that carry into execution. This is a highly cross-functional role. You’ll work side by side with Sales, Project Engineering, Project Managers, Finance, and our internal cell and ESS engineering teams to move opportunities through the sales cycle and hand off projects that are technically sound, cost-effective, and ready to build.
What You'll Do (Responsibilities)
-
Size and configure Peak’s battery systems to the customer’s use case, and build the performance and cost models that support the business case
-
Develop a deep understanding of Peak’s energy storage technology and provide sales teams with technical and financial modeling support and product configuration guidance to drive successful sales
-
Lead discussions with customers and Peak’s internal teams to outline the preliminary design for each opportunity
-
Work with the customer and Peak’s sales team to negotiate technical contracts (scope, schedule, and performance guarantees for both sales and services agreements)
-
Interface with internal stakeholders (Sales, Product Management, Project Engineering, and Project Management) and external parties (utilities, IPPs, AHJs, contractors, and end customers) to ensure consistent communication across all stakeholders
