Your Role:

Accountable for the site Master Production Schedule (MPS) and the S&OP operating rhythm, including Executive S&OP. This leader translates demand into an executable, cGMP-compliant plan by balancing finite capacity across manufacturing, QC testing, and QA disposition. Capacity planning is anchored to batch release timelines to protect customer commitments, stabilize operations, and drive proactive, data-based decisions.

Key Responsibilities:

  • Own and maintain the MPS in SAP; create/adjust production orders with accurate start/finish dates, sequencing, and assumptions.
  • Lead the S&OP cadence (Demand/Supply/Pre-S&OP/Executive); prepare executive-ready materials, decision points, and action tracking.
  • Build and manage finite capacity plans anchored to batch release constraints (QC testing lead times, QA review/disposition, holds/deviations, documentation readiness).
  • Plan backward from release/ship targets; manage queue time and appropriate buffers to improve on-time release and schedule adherence.
  • Align cross-functionally (Manufacturing, Quality, Tech Ops/MSAT, Warehouse, Procurement, Commercial) on priorities, tradeoffs, and recovery plans.
  • Monitor KPIs (schedule adherence, production attainment, on-time release/ship, plan stability); identify trends and drive continuous improvement.
  • Identify bottlenecks across bulk, fill/finish, and packaging; recommend mitigation (campaign strategy, resequencing, shift/overtime, escalation).

Who You Are

Minimum Qualifications:

  • 5+ years in master scheduling/production planning in regulated manufacturing; pharma/biotech/CDMO strongly preferred.
  • Expertise in capacity planning using batch release timelines as the primary planning anchor (QA/QC disposition and testing constraints).
  • Proven experience leading cross-functional planning forums and facilitating executive-level decisions (S&OP or equivalent).
  • Strong communication and influencing skills; able to translate complexity into clear options, decisions, and actions.
  • Working knowledge of SAP (production orders, dates, master data, reporting).

Preferred Qualifications:

  • High-mix / multi-client scheduling experience in a CDMO environment.
  • Excels with planning analytics (advanced Excel; Power BI, Smartsheet).
  • Knowledge of cGMP planning drivers: deviations/CAPA, change control, batch record review, QC sampling/testing workflows, release disposition, validation windows.
