## Job description

Peak Energy

Job Title: Sales Engineer

Location: Burlingame, CA (Preferred) or Broomfield, CO

Department: Commercial (Projects Team)

Reports to: Director of Project Engineering

Position Type: Full-time

## 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
- Build an understanding of regional energy markets, utilities, and customer needs
- Define and disseminate functional requirements to internal business and engineering colleagues to aid in market entry planning, product roadmap, and new feature development
- Build and maintain the technical sales tools and support materials that streamline and scale sales

## What You'll Bring (Qualifications)

- Bachelor’s degree in Electrical, Mechanical, Civil Engineering, or a related field.
- 3+ years of experience in engineering for battery or renewable energy projects.
- Demonstrated experience working on or supporting utility-scale power projects.
- Comprehensive understanding of engineering, construction, and permitting/code compliance concepts.
- Experience reviewing and defining technical scopes of work and supporting contract negotiation.
- Comfort executing multiple projects and tasks in parallel.
- Excellent written and oral communication, with the ability to adapt style and vocabulary to technical and nontechnical stakeholders.
- Strong Excel skills, including building technical and financial models, plus working knowledge of Word and PowerPoint.
- Able to track quickly changing market conditions across storage funding, product development, and the competitive landscape.
- Strong problem-solving skills with attention to cost, constructability, and bankability.
- Eligible to work in the U.S.

- **Mission or purpose**: Deliver the lowest cost electron to the grid, enabling the next era of AI, electrification, and renewable power through abundant, reliable, and domestically manufactured energy storage.

## Products & Services
- **Peak Passive Grid‑Scale Storage System**: A sodium‑ion battery energy storage system (BESS) designed for 20+ year life with zero scheduled maintenance, no augmentation, and passive thermal management. Drop‑in compatible with existing BESS installations, requiring no new installation crews or EMS integration playbooks. Achieves higher round‑trip efficiency (more power to GPUs) and lower total cost of ownership (claimed $75/kWh savings through minimal opex). Fully 48E ITC compliant. Deployed in partnership with nine of the largest U.S. IPPs and utilities.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of **$65M** ($10M seed in October 2023, $55M Series A in June 2024)
