This individual will shape Daye's long-term clinical and medical strategy, guide US market entry and scale, and ensure that scientific excellence translates into real-world clinical adoption.

- Shape Dayes US clinical strategy in partnership with the CEO, Head of US Commercial Strategy, and leadership team.
- Ensure clinical claims, evidence generation, and medical positioning support regulatory, reimbursement, and adoption pathways.
- Guide post-market surveillance and quality-of-care frameworks.
US Market Advocacy & Thought Leadership
- Build Daye's clinical credibility and brand presence across American healthcare communities.
- Represent Daye with public health leaders, policy makers, women's health advocacy groups, cervical cancer organizations, and professional societies.
- Serve as a visible medical ambassador for Daye in the US.
Stakeholder & Ecosystem Engagement
- Develop and maintain relationships with CDC, ACOG, public health institutions, advocacy groups and key women's health networks.
- Facilitate strategic introductions to healthcare systems, academic centers, and clinical leaders.
Publication & Evidence Strategy
- Lead US-focused publication strategy, prioritizing American medical journals and conferences.
- Advise on study design and data packages that support regulatory, payer, and provider adoption.
Clinical Advisory Board (CAB) Development
- Recruit and build a high-caliber US-based Clinical Advisory Board.
- Shape CAB charter, cadence, and focus areas, including quality of care, post-market surveillance, and clinical integration.
Board-Level Contribution
- Serve as an Independent Director, helping shape overarching company strategy.
- Educate the Board on US medical, regulatory, and clinical market dynamics.
- Provide governance-level oversight of clinical risk and opportunity.
Ideal Candidate Profile:
- MD, DO, or equivalent terminal medical degree.
- Active clinician or academically affiliated preferred.
- Background in diagnostics, at-home testing, molecular diagnostics, or women's health strongly preferred.
- Demonstrated experience translating scientific innovation into commercial clinical adoption.
- Strategic company-level experience (e.g., prior CMO, SVP Medical Affairs, or equivalent leadership role).
- Deep networks across OB/GYN, infectious disease, cancer screening, microbiology, or women's health.
- Strong understanding of US healthcare systems, regulatory pathways, reimbursement, and market access.
- Comfortable operating across science, product, regulatory, and commercial.
Who This Role Is For
This role suits a senior medical leader who has participated in scaling at-home or decentralized diagnostics, who values scientific rigor, and who is motivated by moving innovation into everyday clinical practice. The right candidate is intellectually curious, strategically minded, well-networked, and excited to help build the next generation of women's health diagnostics.
