• Strong collaboration skills and the ability to work cross-functionally across sales, engineering, product, and operations
• Commercial awareness and the ability to link technical solution design to customer outcomes and deal progression
• Strong written skills for creating solution overviews, proposals, diagrams, and customer-facing technical content
