About YOCTO

YOCTO is a lifecycle marketing agency for fast-growing DTC and subscription brands. We run email, SMS and retention programs on Klaviyo and Shopify for global brands. Our mission is to become the #1 lifecycle agency for e-commerce brands in the world, and have fun on the way.

Why YOCTO

• Remote-first, European hours. No US night shifts.
• Startup pace, agency variety. You’ll have the opportunity to work across several brands.
• Learning budget to keep you growing: courses, books and tools, all on us.

About the role

As a Senior Retention Strategist, you’ll own lifecycle strategy and performance for 5–7 client brands, leading Strategy Associates alongside a Designer. You’ll have the trust to focus on high-impact work, challenge what doesn’t make sense, and say no to requests that don’t serve the outcome.

What you’ll be doing

• Own the client relationship: Be the main point of contact, set KPIs with each client, and make sure we hit them.
• Build the strategy: Own email and SMS strategy, with roadmaps and calendars prioritised by revenue and long-term retention.
• Own the commercials: Define scope, put hours on the highest-return work, and lead expansion, from upsells to new initiatives and partner integrations.
• Lead your team: Manage Strategy Associates’ performance and growth, and be their go-to escalation point.
• Raise the quality bar: Approve copy (using AI to move faster), spot-check execution, turn wins into case studies, and shape agency playbooks.

Who you are

• 4+ years in e-commerce or lifecycle marketing, owning client strategy and performance (agency or in-house), with deep email and SMS expertise: segmentation, testing and optimisation.
• A problem solver. When results are flat, you dig in until you know why, then fix it. You bring answers, not questions.
• Resilient. (energized by problem solving) (learning opportunities)
• Driven by excellence. You see how every email and report could be better.
• Ahead of your clients. You flag risks early, push back with data, and keep things moving.
• Commercially minded. You prioritise ruthlessly, turn data into clear action, and you’re comfortable talking commercials with clients: scope, upsells and new initiatives.
• Experienced leading or mentoring people and working with design, copy and tech teams.
• Hands-on with Klaviyo (or similar), Shopify and subscription platforms like Recharge or Skio.
• Strong written and spoken English.
• Curious about AI and how it can make work faster and better.
