• Apply systems engineering principles to architect solutions combining cooling technologies, server hardware, manifolds, and integration services.
• Set timelines, milestones, and schedules for successful product development, balancing engineering progress with commercial priorities.
• Oversee initial builds, validation, and first-article production before transitioning to operations for scale-up.
• Work closely with vendors to ensure delivery that is on time and meets specifications to deliver compliant, timely integrated solutions to the customer.
• Communicate progress effectively to internal and external stakeholders, including executive leadership.
• Develop initial Bill of Materials and cost estimates to inform strategic business decisions.
