Giving people the tools they need to maximise life.

Backed by top-tier investors, Numan is already having a positive impact on hundreds of thousands of patients here in the UK, and we want you to help us deliver this mission! We're looking for a highly motivated Senior Lifecycle Marketing Manager to lead CRM growth initiatives within Numan's Marketing Centre of Excellence.   This is a key role for someone who thrives at the intersection of data, creativity, and commercial strategy, using personalised, high-impact communications to convert leads, drive cross-sell and upsell, and unlock compounding growth through referral and promotional mechanics. You'll own CRM growth performance across email, SMS, push, and direct mail, and you’ll work closely with our Performance Marketing team on retargeting strategies, driving revenue and long-term value through intelligent, segment-led campaigns. You'll be: • Own and optimise lead conversion performance, including abandoned basket flow experimentation and iterative improvements to retargeting campaigns across paid social and owned channels. • Develop and execute cross-sell and upsell programmes that encourage existing patients to explore and adopt adjacent categories, grounded in behavioural data and clinical relevance. • Build and improve growth loops throughout the funnel, with a focus on maximising referral programme performance and working cross-functionally to develop new referral capabilities and features. • Drive incremental revenue through carefully-segmented promotional campaigns, applying rigorous segment logic to protect margin and long-term value among high-performing patient cohorts. • Lead test-and-learn initiatives to validate new growth strategies, channels, and creative approaches across the full funnel. • Partner with Data and Analytics to measure, report, and act on campaign performance, revenue contribution, and ROI. • Use segmentation and behavioural insights to deliver personalised, contextually relevant communications at scale. • Collaborate cross-functionally with Paid Media, Product, and Commercial teams to ensure lifecycle and paid channels work in concert, avoiding audience overlap and maximising efficiency. • Champion experimentation and continuous improvement, staying ahead of CRM, growth marketing, and lifecycle trends. • Manage growth projects from planning through execution, ensuring timely delivery and alignment with commercial goals. We’re looking for someone who has: • Proven experience in CRM, lifecycle, or growth marketing roles with a strong track record of driving measurable revenue impact. • Sharp commercial acumen; a natural ability to connect campaign decisions to margin, LTV, and business outcomes. • Hands-on experience with lead nurture, abandoned basket, and retargeting programmes across owned and paid channels. • Experience designing and optimising cross-sell, upsell, and referral programmes at scale. • Technical fluency in CRM platforms such as Customer.io, Braze, or Klaviyo, including campaign setup, QA, and automation logic. • Strong analytical mindset and ability to translate data into actionable growth hypotheses. • Experience developing segmentation strategies and personalised communications that protect value for high-LTV segments. • Excellent project management skills, with the ability to manage multiple campaigns and stakeholders simultaneously. • Exceptional communication and collaboration skills, comfortable influencing across teams including Paid Media and Product. • A proactive, results-driven mindset and genuine comfort operating in a fast-moving, commercially driven environment.
