The job
About the role
Medical and scientific credibility is the foundation of Flo. It's the core of who and what we are.
Our medical teams engage the experts on our medical board (120+ and counting!), establish research partnerships (Stanford University, Johns Hopkins University, Northwestern University, and others), help developers design our intuitive AI tools, check our medical accuracy, and drive medical credibility across the whole platform.
Flo's credibility is also recognised by industry leaders. In October 2026, Google Health announced a multi-year strategic partnership with Flo, bringing together Flo's women's health expertise with Google's wearable technology and AI-powered coaching. Down the line, this collaboration will include consent-based data syncing between the two apps and joint research into underserved areas of women's health, such as perimenopause, PMOS, pregnancy and postpartum recovery. For our medical team, this means even more opportunities to shape how millions of women understand and manage their health, and to hold that work to the highest standard of medical accuracy.
We divide our Medical Advisors into two groups: the User Centric team and the Health Stream team.
The Health Stream Medical team looks after the predictive powers of Flo, working hand in glove with product, engineers and data science to offer a truly powerful predictive experience to the millions of people who trust Flo with their health and wellbeing.
The User Centric Medical team ensures that Flo's health-related features, information and user experiences are medically accurate, relevant, understandable and genuinely useful. We provide medical expertise throughout the product development lifecycle, translating scientific evidence into accessible, actionable health experiences, and advising the wider business on what good looks like when it comes to medical credibility, and on what a clinician says a good user journey should be.
This role sits in the User Centric team. We're looking for a fully qualified doctor with experience in women's health and health tech, who is excited about the role AI can play in medical quality and governance. You'll work alongside highly experienced and supportive colleagues, all experts in healthtech and passionate about improving women's health. Our team is collaborative and always happy to share knowledge, making it a great role for someone ready to make a real impact.
