fleek - Full Stack Growth Builder

• 4-7+ years of lifecycle, CRM, or growth marketing experience. You have owned lifecycle strategy at a company where the systems you built directly impacted retention and revenue. • Hands-on AI and automation experience. You have applied AI to content generation, personalisation, segmentation, or decisioning within CRM systems. Not theoretical, production. • Deep experimentation expertise. Lift testing, holdouts, causal inference, incrementality. You have built experimentation frameworks, not just run A/B tests on subject lines. • Strong SQL skills. You live in SQL and can pull, transform, and analyse large, messy datasets without waiting for someone else to build you a table. • Experience designing adaptive systems. Rules-based, algorithmic, or hybrid decisioning systems that optimise messaging, prioritisation, timing, and frequency. • Consumer or marketplace background. You have worked at a marketplace, ecommerce, or consumer company. You understand how activation, retention, and monetisation interact. • Strong product intuition. You balance short-term optimisation with long-term customer trust and experience. • Startup or scale-up experience. You have worked in environments with fast cycles, evolving data infrastructure, and high ownership. • Experience with Python or R for statistical modelling and analysis • Familiarity with data warehousing tools (BigQuery, Snowflake, dbt) • Experience building CRM/lifecycle infrastructure from scratch • Background in building tools or internal products (not just campaigns) • Ready to build the lifecycle engine behind one of the fastest-growing marketplaces in Europe? If you want to architect systems that learn, prove what actually works, and ship at speed with a world-class team, we would love to hear from you. • Fleek is an in-office company. We believe the best work happens when people are together, the quick decisions, the cross-functional energy, the ability to solve problems in real time. Most of the team works from our London HQ 3-4 days a week. • We are not prescriptive about it. Performance and trust matter more than attendance. For your first six months, we will ask you to prioritise being in the office, to learn the business, build relationships, and get up to speed. After that, you will have genuine flexibility to manage your own time. We hire adults and treat them accordingly. • THE PRACTICALITIES • Location: London HQ, Heneage Street, E1 (Shoreditch / Aldgate East) • Work model: In-office, typically 3-4 days per week. Full-time in the office for your first six months, then genuine flexibility earned through trust and performance. • Level: Senior • Stage: Post-Series B, hyper-growth • Team: 100+ across London, India, and Pakistan (~20 in London office) • Culture: High ownership, non-hierarchical, fast-moving. Founder-led with strong opinions loosely held. • Five values shape how we work at Fleek: • Dream Big and Disrupt Yourself: Push the most ambitious version of what you are building. Step out of your comfort zone. Nothing is out of reach. • Absolute Ownership: The buck stops with you. Drive initiatives to completion. Experiment, learn, persevere. The job is not done until the job is done. • Curiosity Leads the Way: Do not accept anything at face value. Ask questions you do not know the answer to. That is how you innovate. • Talk to the Customer: Deeply understand their challenges, motivations, and ambitions. Every decision starts with the customer at the centre. • Embrace Diversity: A global team building for a global supply chain. Bring your authentic self and embrace the diversity of everyone you encounter.
