  • Identify cost variances and provide root cause analysis with actionable insights.

• Budgeting & Forecasting:

  • Support the preparation of forecasts / budgets and longer-term strategic financial plans for the semiconductor back-end operations.
  • Collaborate with cross-functional teams to align financial plans with operational goals.

• Reporting & KPIs:

  • Develop and maintain cost dashboards and performance indicators.
  • Provide regular reports to management on cost trends, efficiency metrics, and cost-saving opportunities.

• Process Improvement:

  • Partner with engineering and production teams to identify and implement cost-reduction initiatives.
  • Evaluate the financial impact of process changes, yield improvements, and capacity expansions.

• Inventory & Asset Control:

• Strong understanding of back-end semiconductor processes and cost drivers.
• Proficiency in ERP systems (e.g., SAP) and advanced Excel skills.
• Excellent analytical, communication, and problem-solving abilities.
• Ability to work cross-functionally in a fast-paced, high-tech environment.

Preferred Skills:

• Knowledge of semiconductor industry cost structures and market dynamics.
• Familiarity with lean manufacturing, Six Sigma, or other process improvement methodologies.

Home Office and Travel Requirements:

• Position to be based at Vishay Asia regional headquarters in Singapore, or at any of our primary back-end manufacturing facilities (including Shanghai, China; Tianjin, China; Kaohsiung, Taiwan; and Melaka, Malaysia) provided candidate is willing to travel.
• Position requires periodic travel to back-end manufacturing facilities.
