Job Description

The Front-End Capacity and Materials Planner supports tactical capacity and materials planning for internal and external front-end manufacturing sites. This position requires collaboration with cross-functional partners to maintain accurate planning data, monitor supply and capacity, and identify potential constraints. This role offers opportunities to build semiconductor planning expertise and take on greater responsibility as skills develop.

• Perform weekly wafer starts planning, factory loading optimization, and execution alignment to support customer demand, revenue objectives, and operational performance.
• Monitor execution against approved wafer starts and factory loading plans, identify plan-to-actual gaps, and coordinate follow-up actions with manufacturing partners.
• Maintain capacity models, planning system inputs, dashboards, metrics, and recurring reports in accordance with established processes; validate data accuracy and investigate discrepancies with guidance.
• Execute monthly capacity reviews, forecast updates, scenario analysis, and evaluate loading alternatives and capacity trade opportunities.
• Own substrate and epitaxial wafer (Sub/Epi) supply planning for assigned materials, including demand forecasting, supplier order management, inventory health and commitment tracking, and identification and escalation of potential material shortages and supply risks.
• Analyze demand, capacity, inventory, and supply data to identify emerging constraints, gaps, and execution risks; support mitigation planning and follow-up.
• Partner with Manufacturing, Supply Planning, and Procurement leaders to coordinate responses to supply disruptions, material shortages, quality issues, and expedite requirements.
• Learn and follow standard planning procedures, maintain process documentation, and contribute to continuous improvement and process standardization.

• Communication – Delivers clear, concise written and verbal updates on planning status, data discrepancies, and potential risks.
• Continuous Learning – Demonstrates curiosity, develops knowledge of semiconductor manufacturing and planning systems, and applies feedback to strengthen skills.
• Analytical Thinking and Attention to Detail – Reviews data accurately, identifies trends and inconsistencies, and seeks guidance on issues outside established procedures.

Requirements:

• Bachelor’s degree in Supply Chain, Engineering, Operations Management, Business, or a related field.
• 1–2 years of experience in supply chain, materials planning, production planning, capacity planning, or a related manufacturing role. Relevant internship or co-op experience may be considered.
• Foundational knowledge of supply chain and manufacturing planning concepts, with an interest in developing expertise in front-end semiconductor operations. Semiconductor experience is preferred but not required.
• Foundational analytical and problem-solving skills, strong attention to detail, and proficiency in Microsoft Excel for analyzing and reporting data.
• Willingness to learn planning tools and maintain accurate system data. Exposure to enterprise resource planning (ERP) or advanced planning systems (APS) is preferred but not required.
• Effective written and verbal communication skills, a collaborative approach, and the ability to manage assigned priorities with guidance.
