Lennox International Inc. (LII) is a global leader in energy-efficient climate-control solutions. Dedicated to sustainability and creating comfortable and healthier environments for our residential and commercial customers while reducing their carbon footprint, we lead the field in innovation with our air conditioning, heating, indoor air quality, and refrigeration systems.

Heatcraft Worldwide Refrigeration is a long-standing leader in the world of commercial refrigeration, providing climate-control solutions to customers in more than 70 countries. Their state-of-the-art manufacturing facilities in the cities of Stone Mountain and Tifton, Georgia, produce evaporators, condensers, compressor racks, and other top-quality refrigeration products for their five market-leading brands: Bohn, Larkin, Climate Control, Chandler, and InterLink.

This position is 100% remote.

As a Lead Field Support Engineer, your day starts with perspective and prioritization.

You are focused on higher-impact, higher-complexity work. You review escalated cases, critical start-ups, repeat issues, and field challenges that require advanced technical judgment. You help determine where Heatcraft’s resources are best applied and when additional investigation or alignment is needed before action is taken.You regularly support and mentor other Field Support Engineers, providing guidance on troubleshooting approaches, system evaluation, documentation, and customer communication. Sometimes that means helping an engineer think through a problem remotely; other times it means stepping in directly when experience and authority are required. Some days you are in the field supporting complex systems, large projects, or emerging technologies.

On site, you are often the senior technical voice — working directly with contractors, customers, and internal stakeholders to assess system performance, identify root cause, and guide resolution. Your presence helps bring clarity, confidence, and structure to challenging situations. Other days are spent supporting remotely at an advanced level. You may review wiring diagrams, photos, controller data, trend logs, or commissioning documentation. You help distinguish between equipment issues, application challenges, and installation-related concerns, ensuring the correct path forward is clearly defined and communicated.

Documentation and communication are critical parts of your role. You provide clear, thorough technical summaries that support Engineering, Quality, Warranty, and Product teams. Your feedback helps identify trends, improve designs, refine procedures, and prevent repeat issues in the field. Throughout the day, you balance technical problem-solving with leadership by example. You communicate professionally, manage expectations, and represent Heatcraft with credibility and consistency — whether working directly with a customer or supporting the broader field team.
