Senior Engagement Strategist

OLIXIR is a next-generation healthcare agency, created by uniting FCB Health London and McCann Health London as part of Omnicom Health’s evolving European structure. By bringing our teams together and combining our strengths, we’re building something entirely new: a more agile, more connected, and more ambitious partner for healthcare brands. OLIXIR blends award-winning creative excellence with deep scientific expertise, strategic thinking that drives meaningful brand growth, and fully integrated production ’re also unlocking new innovation opportunities, powered by AI and future-focused ways of working.

While our name is new, our people, values, and commitment are not. You’ll find the same trusted teams, the same high standards, and the same passion for creating work that makes a real difference to patients and healthcare professionals, alongside new possibilities to grow, innovate, and shape what’s next. OLIXIR is built for the future of healthcare communications - and this is just the beginning.

Working within the Engagement Strategy team, the Senior Engagement Strategist is responsible for leading the development of integrated, omnichannel engagement strategies and customer experiences for our clients’ brands. At its core, the role is about understanding audiences, their behaviours and needs, and the environments in which they engage with healthcare brands. The Senior Engagement Strategist brings together audience insight, customer experience, channel strategy, content, data, technology and measurement to create clear, actionable engagement strategies that deliver against client and brand objectives.

The Senior Engagement Strategist will lead engagement strategy projects and pitches from brief interpretation through to strategic development and client-ready recommendations, working with oversight from senior leadership where appropriate. They will collaborate closely with media, data and analytics, creative, technology and account teams to turn strategic thinking into practical, integrated campaign plans.

You’re a strategic thinker who understands how people engage with healthcare brands and can turn complex information into clear, actionable recommendations. You’re confident working across the full omnichannel ecosystem and understand how audience needs, content, channels, data, technology and measurement connect to create effective customer experiences. You’re comfortable taking ownership of a project from brief through to recommendation, while bringing the right people together to strengthen the thinking.

You can confidently engage clients, lead workshops and present your point of view, and you know how to balance strategic ambition with practical delivery. You’re curious about people, behaviours, technology and the changing healthcare landscape. You’re collaborative by nature, able to work effectively across disciplines, and are ready to provide guidance and support to more junior members of the team.

Engagement Strategy Lead engagement strategy projects and pitches end-to-end, turning complex or unclear briefs into a clear strategic approach and activation-ready, client-ready recommendations, with little senior oversight.

Develop integrated omnichannel engagement strategies and customer experiences across HCP, patient and wider healthcare audiences.

Apply audience segmentation, persona development and behavioural/customer insight to inform engagement strategy, synthesising qualitative, quantitative, attitudinal, behavioural and performance evidence alongside relevant data, research and market inputs.
