About The Position

As the Sr. Field Support Engineer, your day often starts by reviewing open cases, field requests, or scheduled site visits. You may be coordinating with internal teams like Technical Support, Engineering, Sales, or Product Services to align priorities, clarify scope, or ensure the right parts, documentation, and information are in place before a trip ever begins. Some days you’re traveling to a customer site — a distribution center, food processing facility, or large commercial installation — to support start-ups, commissioning, or complex troubleshooting. On site, you are the calm, experienced presence. You listen first, assess the system holistically, and separate installation issues from equipment issues using sound refrigeration fundamentals. You may be working on single systems, rack systems, or newer technologies involving A1, A2L, or A3 refrigerants. Other days are spent supporting the field remotely. That may mean walking a contractor through diagnostics, reviewing wiring photos or trend logs, or helping interpret control data to get a system back online — often under real-world pressure where downtime matters. You’re trusted not just for your technical knowledge, but for your judgment and ability to explain complex issues clearly and professionally. Documentation is part of the job — not paperwork for paperwork’s sake, but clear, accurate reporting that helps the next person succeed. You capture findings, root causes, corrective actions, and recommendations in a way that adds value to the organization and improves future outcomes. Throughout the day, you’re balancing multiple requests, prioritizing based on impact, safety, and urgency. You communicate clearly, manage expectations, and represent Heatcraft with professionalism — whether you’re speaking with a contractor on a noisy job site or collaborating with engineers back at the office. By the end of the day, you’ve likely solved problems, prevented future ones, and helped customers move forward — sometimes visibly, sometimes behind the scenes. You may not always get the spotlight, but your work matters, and people know they can rely on you when it counts.
