Responsibilities

• Own email and lifecycle marketing end to end, from data architecture through to revenue. You will design and build the entire Klaviyo account: the flow logic, the segmentation model, the event and property schema, and the testing programme that compounds performance over time. This is a hands-on senior role with full autonomy. You build it, you ship it, you own the result.
• Architect and maintain the full flow library, including welcome and onboarding series, browse and cart abandonment, checkout abandonment, post-purchase and review-generation, replenishment and reorder logic, win-back and sunset flows, and back-in-stock
• Build flows with proper conditional logic: trigger filters, flow filters, conditional splits, trigger splits, and time delays tuned to real purchasing behaviour rather than defaults
• Use Klaviyo metrics, custom properties, and event data to drive personalisation, not just merge tags. This includes dynamic product blocks, predictive analytics (CLV, churn risk, predicted next order date), and catalogue-driven recommendations
• Design replenishment and reorder logic around consumption cycles specific to our product range, using purchase history and predicted reorder timing rather than fixed intervals
• Own the segmentation model: build and maintain definitions based on engagement, purchase frequency, AOV, product affinity, lifecycle stage, and channel, and keep them clean as the data grows
• Manage the data layer: event tracking, custom properties, profile hygiene, and the integration between Shopify and Klaviyo so the right data lands in the right place
• Build and respect a single-variable testing discipline across subject lines, send timing, creative, offers, and flow paths, with results documented and fed back into the roadmap
• Set up and maintain reporting that ties flows and campaigns to attributed revenue, per-recipient value, and contribution to retention, not vanity metrics
• Own deliverability as a discipline, not an afterthought: SPF, DKIM, DMARC, and dedicated sending domain setup and monitoring
