• Work closely with to gather and interpret source data for accurate document content.
• Partner document strategy, timelines, and prioritization across the program portfolio.

Oncology & Scientific Expertise

• Apply strong working knowledge of oncology clinical development (trial design, endpoints, safety considerations, and regulatory pathways specific to oncology) to ensure documents reflect appropriate scientific and clinical context.
• Stay current on relevant regulatory guidance (FDA, ICH, EMA) and oncology-specific requirements (e.g., accelerated approval, breakthrough therapy, orphan drug designation) that may affect document content and strategy.

Process, Quality & Standards

• Ensure documents comply with CTD formatting and structure, applicable style guides, and internal templates.
• Maintain consistency of terminology, data presentation, and referencing across related documents.
• Support the development and refinement of templates, style guides, and medical writing best practices as the function matures.
• Manage and perform (when appropriate) quality control (QC) and review cycles, incorporating cross-functional feedback while maintaining document integrity and timelines.
• Coordinate with external medical writing vendors/consultants as needed for surge capacity, while retaining ownership of quality and strategy.
