Manager, Clinical Supply Chain - Planning

Overview:

We are seeking an experienced individual for the role of Manager - Clinical Supply Chain, Planning. In this position, you will play a key role in developing and maintaining clinical supply plans across programs, supporting Alnylam's growing pipeline and patient needs.

Your focus will be on creating accurate, decision-ready demand and clinical finished good supply plans, ensuring alignment between protocol design, planning assumptions, and execution realities. You will partner closely with cross-functional teams including Clinical Operations, CMC, Global Planning, Regulatory Affairs, and Clinical Supply Chain Operations to ensure clinical supply strategies are well-defined and feasible.

• Develop integrated CFG supply plans that align forecasted demand with inventory strategy, ensuring adequate supply while minimizing overage, expiry risk, and waste across studies and programs.
• Anticipate and quantify future supply risks (assumptions, scenarios, and constraints), and recommend mitigations and tradeoffs before they impact trial continuity.
• Collaborate closely with Global Planning and CMC to relay demand forecasts into manufacturing, packaging, and release plans, ensuring alignment on lead times, capacity constraints, and material availability.
• Engage with Program Development / Clinical Teams to validate and refine forecasting assumptions based on evolving study designs, enrollment dynamics, and protocol changes, ensuring forecasts reflect latest program reality.
• Partner with Finance to connect demand forecasts to long range budget planning, and scenario modeling.

Qualifications:

• B.Sc. in a scientific field or Supply Chain Management or related field.
• 4+ years of direct Clinical Supply Chain experience globally.
• Knowledge of GMP / GxP / GCP and global regulatory requirements (FDA, EU, etc.).
• Strong knowledge of clinical supply chain (packaging, labeling, inventory, global distribution) to enable accurate forecasting.
• Understanding of clinical trial operations and drug development lifecycle.
• Strong analytical and problem-solving skills with ability to track forecast accuracy and inventory performance.
• Excellent communication and stakeholder management, with ability to clearly present forecasts, risks, and trade-offs.
• Proven ability to operate in a fast-paced, matrixed environment while managing multiple studies with high accuracy and accountability.
• Proficient knowledge of MS Office (Excel, PowerPoint, Visio, Project, etc.).
