Senior Medical Content Writer

Position Title: Senior Medical Content Writer

Work Location: South San Francisco, CA

Assignment Duration: 3 Months

Work Schedule: Monday through Friday, 8am to 4pm

Work Arrangement: Hybrid (Tue-Wed-Thu in office)

Position Summary:

• We are looking for a Senior Medical Content Writer who can do the hardest kind of writing in pharma: claims. You will develop, substantiate, and annotate promotional and educational claims, and write the medical content that carries them - accurately, clearly, and in a way that survives MLR review without losing its edge.
• You will work embedded in an in-house creative studio, alongside creative directors and designers, which means your writing needs to work as creative material, not just as reference text.

Key Responsibilities:

• Draft, refine, and substantiate promotional and non-promotional claims grounded in clinical data, prescribing information, and peer-reviewed literature.
• Build annotated references and claim substantiation packages ready for MLR submission.
• Write medical content across formats: HCP materials, patient education, disease-state content, congress panels, digital assets, video scripts, and sales materials.
• Ensure fair balance, accurate ISI integration, and on-label alignment in all promotional content.
• Partner with medical affairs and regulatory reviewers to resolve claim language efficiently; anticipate objections and offer compliant alternatives proactively.
• Collaborate with creative directors and designers so that copy and visual concepts develop together rather than sequentially.
• Maintain claim libraries and reference databases to accelerate reuse across the portfolio.

Qualification & Experience:

• 5-8 years of medical writing experience in pharma, biotech, or a medical communications agency, with direct experience writing and substantiating claims.
• Deep familiarity with the MLR review process and what makes claims approvable: substantiation standards, referencing conventions, and common reviewer objections.
• Strong command of AMA style and the ability to read and accurately interpret clinical trial data, publications, and prescribing information.
• Understanding of FDA/OPDP promotional regulations, fair balance requirements, and ISI standards.
• Range as a writer: able to move between rigorous scientific accuracy and accessible, engaging language for different audiences (HCP, patient, internal).
• Meticulous attention to detail in referencing, annotation, and version control.

Nice to Have

• Advanced degree in life sciences (PharmD, PhD, MS) or equivalent scientific depth.
• Experience with Veeva Vault PromoMats annotation workflows.
• Oncology, immunology, or biologics therapeutic area experience.
• Experience working inside an in-house studio or embedded content team.
