• Develop and execute talent development plans for each KAM, identifying skill gaps in product knowledge, application expertise, and executive relationship management
• Recruit, onboard, and ramp new KAMs as the HVAC OEM sales organization scales with market growth
• Build a high-performance team culture rooted in Littelfuse's solution-selling framework: customer needs first, full portfolio positioning, design-in focus, and long-term partnership mindset
