Lifecycle Specialist (Klaviyo)

Role

OENA® is looking for a Lifecycle Specialist to own the retention engine behind the brands we partner with — the strategy, design, and build of every email and SMS touchpoint that turns first-time buyers into loyal customers.

This is a hands-on strategic role. You'll design and build lifecycle programmes end to end in Klaviyo — mapping the customer journey, then executing the flows, campaigns, and segmentation that drive LTV and reduce churn. You'll work directly with founders and senior stakeholders, and closely with our paid and creative teams so that acquisition and retention operate as a single system.

Responsibilities

• Own lifecycle strategy across the full customer journey — from welcome and post-purchase through win-back and VIP.
• Design and build email and SMS flows and campaigns in Klaviyo, from concept through to live.
• Design the emails themselves — layout, hierarchy, and on-brand creative that performs, not just looks good.
• Build and manage segmentation, ensuring the right message reaches the right customer at the right time.
• Architect subscription journeys and loyalty programmes that increase retention and repeat rate.
• Own A/B testing and iterate flows and campaigns based on performance.
• Build clear, commercially focused client reporting through OENA® Lens, our proprietary dashboard.
• Continuously test, refine, and optimise against LTV, retention, and revenue targets.

Experience

• 2–4+ years in lifecycle, email, or CRM within an agency or D2C brand.
• Deep, hands-on Klaviyo experience — building flows and campaigns, not just scheduling sends.
• A strong design eye, with the ability to design emails as well as build them.
• Experience architecting subscription journeys (Recharge, Skio, or similar).
• Experience building loyalty or VIP programmes.
• Strong grasp of segmentation and lifecycle strategy across the customer journey.
• Commercially minded, analytical, and detail-oriented.
• Klaviyo certification a plus.

This is a fully remote, contract role. You'll work within UK business hours, with some flexibility to overlap with US client time zones when needed.

Agency

OENA® (OH-en-ah) is a creative growth partner for ambitious ecommerce brands, built at the intersection of technology and marketing and shaped by Japanese design and European refinement.

We run the full performance engine as one connected system — experience (Shopify and CRO), growth (paid media across Meta, Google Ads and TikTok), and retention (lifecycle on Klaviyo) — pairing deep channel expertise with AI-driven execution. The result is growth that compounds: more buyers, higher LTV, and brand equity that lasts.
