- 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
