Principal Demand & Capacity Planning Architect

Broadcom•Breinigsville, PA

1d•$110,800 - $177,300

About The Position

We are seeking a highly analytical and hands-on Demand & Capacity Planner to lead the transformation and subsequent sustaining of planning capabilities within a fast-paced semiconductor manufacturing environment. This role will be critical in evolving the organization from manual, Excel-based wafer start planning to a scalable, system-driven approach. The ideal candidate has deep experience in semiconductor wafer fab operations, understands re-entrant flows and cycle time variability, and has successfully refined planning processes.

Requirements

Bachelor’s degree in Engineering, Supply Chain, Operations, or related field (Master’s or PhD preferred).
12+ years of experience in semiconductor manufacturing or planning.
Strong understanding of: Semiconductor wafer fab operations, Re-entrant manufacturing flows, Cycle time drivers and variability, WIP management, bottlenecks, and throughput optimization.
Proven experience building planning systems from Excel/manual processes.
Hands-on experience with MES, ERP, and Data analytics systems.
Expertise in developing wafer start and capacity models.
Strong analytical and quantitative modeling skills.
Ability to operate in ambiguity and build scalable solutions.
Excellent stakeholder communication across technical and management teams.
Proven change agent in operational transformation.

Nice To Haves

Lean/Six Sigma certification or equivalent process improvement experience.
Familiarity with data tools (SQL, Python, JMP).
Experience in high mix/low-volume or complex manufacturing environments.

Responsibilities

Develop and own wafer start plans aligned with demand forecasts, fab capacity, and strategic priorities.
Translate customer demand into executable fab loading plans across multiple toolsets and process layers.
Balance near-term execution (S&OE) with long-term capacity planning (S&OP).
Build and maintain detailed capacity models incorporating: Tool group capacities and constraints, Re-entrant flows, Cycle time variability, WIP profiles and queue dynamics.
Identify bottlenecks and drive corrective actions to improve throughput and cycle time.
Perform scenario analysis to evaluate trade-offs between utilization, cycle time, and service levels.
Develop advanced models to estimate cycle time, throughput, and capacity.
Implement dashboards and KPIs including: Capacity utilization, Cycle time and variability, Forecast accuracy, Plan adherence.
Enable “what-if” simulation capabilities for demand volatility and fab disruptions.
Partner with local and overseas operations, engineering, supply chain, and finance teams to align plans.
Communicate risks, constraints, and recommendations to management leadership.
