Position Summary

As a Scientific Leader in the Analytical Projects-US department, within AD, you will be a member of a highly skilled team of scientists responsible for the development, validation, and implementation of various analytical methods and state-of-the art analytical technologies. You will lead efforts to develop methods that focus on product quality and process-specific analytes and support various aspects of small molecule, mAb and/or Antibody Drug Conjugate (ADC) process development and manufacturing. You will be involved in all aspects of pharmaceutical development, including engagement with CMC project teams and other stakeholders for various projects in different stages of development. 

As a Scientific Leader, you will oversee and be involved with the development, validation, and transfer of analytical methods that employ such techniques as HPLC, dissolution, UV, CAD and MS. This role requires excellent verbal and written communication skills, impeccable organization, and broad scientific knowledge. Because the role will require both collaborative and independent work, the ideal candidate will also possess good interpersonal skills, an open mindset, and the capacity for self-motivation.  You will apply deep technical expertise in analytical development to support both early‑ and late‑phase assets, including method lifecycle management, product characterization, and the introduction of state‑of‑the‑art analytical technologies. You may also share this expertise across large molecule and small molecule modalities supported by the department.

Key Responsibilities

• Be a key member, or leader, of matrix analytical teams in the early or late small molecule, mAb and/or ADC development phase. Ensuring that analytical methods, control strategies, and GMP release and stability deliverables are advanced to ensure project pipeline progression.
• Serve as a departmental expert in key analytical techniques—leading troubleshooting, enabling innovation, and integrating new technologies to support program and organizational goals.
• Be involved in GMP compliance activities, including instrument qualification, deviation management, and change control processes.
• Drive standardization and best practices across analytical platforms to enhance harmonization, operational efficiency, and quality.
• Act as a subject matter expert during regulatory inspections, GMP audits, and agency interactions, effectively representing analytical strategy, methods, and supporting data.
• Author and review high‑quality documentation, including scientific papers, patents, regulatory submissions, CQAs, and specifications, ensuring scientific rigor and clarity.
• Author regulatory submissions (IND/IMPD through to NDA/MAA).
• Perform complex data analysis and interpretation to support decision‑making for both drug substance and drug product development.
• Collaborate cross‑functionally with R&D, Global Supply Chain (GSC), and external partners to resolve analytical challenges and ensure seamless program progression.
• Be a mentor to less experienced staff and share your experiences.
• Oversee method and process development activities, including qualification, validation, technical transfer, and continuous improvement initiatives, with strong documentation and knowledge‑sharing practices.
