• Translate customer discussions into clear, well‑aligned internal actions and priorities.
• Demonstrate strong internal and external communication skills, ensuring clear, targeted information sharing and consistent customer messaging.
• Partner closely with customers by operating at their pace and responding with urgency and agility; lead and influence internal teams to align to the same level of responsiveness and execution excellence.
• Own execution details across open order reviews, RMA coordination, quote follow‑up and status clarity, and escalation management.
• Proactively identify technical, commercial, supply, and timing risks and lead effective mitigation efforts.
• Identify opportunities for system‑level improvements (processes, tools, workflows) that improve speed, transparency, and execution quality.
• Collaborate with cross‑functional partners to design and implement sustainable process improvements.
