• Conduct regular 1:1 coaching sessions, pipeline reviews, and deal strategy sessions with KAMs — moving from product selling to consultative, solution-based engagement
• 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
• Facilitate cross-team knowledge sharing — ensuring KAMs learn from each other's OEM wins, competitive displacement strategies, and custom solution successes
• Represent the team's needs and resource requirements to the Director, OEM Sales — EII, Americas during headcount planning, training prioritization, and marketing investment discussions

• Oversee and maintain a healthy, well-qualified opportunity pipeline in CRM (Salesforce) across the full team, with accurate forecasting and stage progression
• Identify and direct KAMs toward new HVAC OEM account activation targets from the Tier 2 list to expand Littelfuse's market penetration and reduce customer concentration risk
