Principal Scientist, Cleaning Verification Center of Excellence Strategy Lead, Pharmaceutical Analysis and Digital Technologies
Merck
Summary
The Pharmaceutical Analysis and Digital Technologies (PADT) team has an opening for a Principal Scientist to serve as Strategy Lead for our Cleaning Verification Center of Excellence (CoE), based in Rahway, NJ. In this role, the Principal Scientist will define and lead the strategy for the Cleaning Verification CoE, establishing harmonized, science- and risk-based approaches to cleaning verification across all modalities in our clinical portfolio, including small molecule (e.g., oral solid dosage forms and sterile liquids) and large molecule programs.
Job description
The Strategy Lead will drive the development, validation, and lifecycle management of cleaning verification methods and practices, ensuring cGMP compliance, operational excellence, and a sustained state of inspection readiness. The Principal Scientist should be engaged with regulatory and industry trends, including health-based exposure limits (HBELs), and have thorough working knowledge of cGMPs, ICH, and relevant FDA and global health authority expectations for cleaning verification and validation.
In addition, the Strategy Lead will partner with Analytical leadership, extended leadership teams, and cross-functional stakeholders in Process Engineering, Clinical Manufacturing, and Quality to identify and advance key departmental strategic and cultural initiatives. As the recognized subject matter expert, the Principal Scientist will mentor scientists and build cleaning verification capability across the organization through training, knowledge sharing, and coaching. The role will also be responsible for proactive resource planning, risk assessment strategies, and continuous improvement of CoE processes, standards, and tools.
Primary Responsibilities
- Technical expertise in analytical methodologies applied to cleaning verification for both small and large molecules, such as liquid chromatography, total organic carbon (TOC), spectroscopy, and conductivity, including swab/rinse sampling and recovery studies.
- Define and execute the Cleaning Verification CoE strategy and roadmap, including harmonized standards, best practices, and governance across programs and sites.
- Lead the development, validation, and transfer of cleaning verification methods to enable on-time, right first-time equipment release for clinical manufacture of drug substance and drug product.
- Partner with Process Engineering, Clinical Manufacturing, and Quality to establish science- and risk-based cleaning acceptance limits across small and large molecule modalities (e.g., HBEL-based carryover calculations).
- Provide technical and compliance oversight on cleaning-related lab investigations and deviations including root cause analysis and identification of robust corrective and preventative actions.
- Review and approval of cleaning verification data, protocols, technical reports, and SOPs.
- Serve as the cleaning verification subject matter expert during internal and external compliance audits and regulatory inspections.
- Drive operational excellence, innovation, and process improvements, including evaluation and implementation of new analytical technologies and digital tools.
- Technical mentorship and development of scientists, building cleaning verification capability across the organization.
- Cross-functional leadership and influence, including working with senior management to drive departmental strategic and cultural initiatives.
