The Key Account Manager (KAM), Renewable Energy is responsible for owning and growing strategic relationships with top renewable OEMs, Tier-1s, and ecosystem partners across solar, wind, energy storage systems (ESS), and EV charging infrastructure. You will lead account strategy, expand BOM content using Littelfuses power electronics and protection portfolio, and accelerate design-wins from concept through SOP. Success will be measured by multi-year revenue growth, share expansion, design-in pipeline conversion, and executive-level account health.

• Account Ownership & Growth

• Build and execute multi-year account plans for top renewable OEMs/Tier-1s; deliver ARR and share gain targets.
• Develop C‑suite and director-level relationships across R&D, sourcing, program management, and operations.
• Drive price-for-value strategies and long-term agreements (LTAs/MLAs) that balance margin, risk, and service.

• Design-In & Application Expansion

• Identify and win new sockets across DC/AC protection and power control: fuses, high-speed fuses, TVS/SPDs, contactors/relays, semiconductor protection, current/temperature sensors, power distribution modules.
• Orchestrate cross-functional pursuit teams (FAE, Product Management, Quality, Supply Chain) to secure design-wins in inverters, DC combiner boxes, string/central inverters, BESS packs/racks, PCS, EMS, switchgear, and DC fast chargers.
• Translate technical and compliance requirements (UL, IEC, NEC, CSA) into clear value propositions and proposals.

• Pipeline & Forecast Management

• Build a healthy opportunity funnel across NPI and sustaining business; manage forecast accuracy (90%) and commit-to-ship execution.

• Partner with Channel/Distributor managers for coverage, POS growth, and design registration effectiveness.

• Voice of Customer & Portfolio Influence

• Capture VOC to shape roadmaps for high-voltage, high-current protection and sensing needs (e.g., 1,500Vdc PV, 800-1,200V BESS, SiC/GaN inverter topologies, UL 2579/248/1741/9540A implications).
• Provide competitive intelligence (spec, price, service levels) and win/loss analyses to Product/Marketing.

• Operational & Quality Stewardship

• Escalate and resolve delivery, quality, and engineering change topics; drive 8D/PPAP where applicable.
• Ensure compliance with customer onboarding, supplier portals, and EHS & sustainability requirements.
