In this role, you will author and participate in the review of high-quality CMC documentation, with a primary focus on global Biologics License Applications (BLAs), Marketing Authorisation Applications (MAAs), and New Drug Applications (NDAs). Working closely with scientific and technical experts, you will translate complex manufacturing, analytical, and formulation development information into clear, accurate, and consistent regulatory submission documents.

You will join a dedicated team of CMC writers and collaborate with colleagues and external partners across late-stage development, regulatory submission, and lifecycle management activities. Your contribution will help ensure that CMC documentation presents a coherent scientific rationale and is delivered within agreed submission timelines. You will also contribute to improving writing quality and efficiency through the thoughtful use of AI and digital tools.

The position reports to the Director, Head of CMC Writing, and is based in Copenhagen, Denmark.

Key Responsibilities

Your primary focus will be CMC documentation supporting global BLA/MAA/NDA filings and responses to health authority questions during assessment.

Your responsibilities include:

• Authoring and reviewing Module 3 CTD sections, covering manufacturing processes, process controls, analytical procedures, characterization, specifications, formulation development, stability, and facility
• Translating technical reports and source data into clear, scientifically sound regulatory narratives in close collaboration with subject matter experts
• Coordinating document preparation and review with CMC Project Managers, subject matter experts, Regulatory Affairs CMC, Quality Assurance, and external partners, including contract manufacturing organizations
• Consolidating review comments, facilitating their resolution, and ensuring that documents are completed and approved within agreed timelines
• Verifying the accuracy of data presented in CMC documents against source documentation and ensuring consistency across related sections and submissions
• Authoring and coordinating responses to health authority questions and implementing the resulting updates to CMC submission documents
• Maintaining source document trackers and ensuring traceability of supporting information and regulatory document updates
• Supporting lifecycle maintenance of CMC documentation, including post-approval changes, and contributing to IND/CTA submissions and amendments as needed
• Applying AI and digital tools to improve writing quality, consistency, and efficiency, while critically evaluating outputs and ensuring scientific accuracy and appropriate handling of confidential information
• Following and contributing to the continuous improvement of CMC writing and response principles, templates, internal procedures, and style guides
