The goal is to maximize sales and margin while ensuring flawless technical execution (speed, stability, compatibility) and continuous marketing iteration (A/B testing, UX flow, wording). You will organize and grow the local MarTech team, manage workflows with autonomy, and serve as a central interface between regional and group stakeholders. Key Responsibilities Product & Delivery - Prioritize, plan, and deliver new LPs, variants, and market/operator adaptations with fast time-to-market and stable quality. - Build and maintain a CRO experimentation backlog: hypotheses, variants, success criteria, A/B testing calendar. - Standardize winning UX patterns into reusable templates, components, and QA checklists. Technical Excellence (Performance & Quality) - Guarantee ultra-light, high-performing pages (minimal weight, optimized requests), fully responsive and cross-device. - Organize code reviews, systematic QA (functional + analytics), post-mortems, and incident follow-ups. - Stay up-to-date on technical innovations (web performance, operator compatibility, security, antifraud) and benchmark competitors. CRO & Data-Driven Optimization - Design and execute A/B tests at scale, analyze results with the Data team, and industrialize winning variations. - Continuously optimize copywriting, visual hierarchy, micro-interactions, and payment/consent funnels. - Build actionable performance dashboards (per country, offer, acquisition source). Team Management & Development - Provide structure and clarity: rituals (daily/weekly), objectives, ownership rules, definition of done. - Coach and develop team members: skill progression, peer programming, knowledge sharing. - Select and manage external providers when needed (peak workloads, design, illustrations). Governance & Communication - Act as the daily interface with Advertising (traffic needs, iterations), Product (post-signup handoff), IT (billing, operator specs), BizOps (country priorities), and Data (tracking, modeling). - Provide regular reporting to the Regional Operations Director (business) and the MarTech Director (methodology, standards, best practices). Success Metrics (Examples) - ≥ 4 CRO experiments per month on each priority country. - Median CR uplift on key verticals vs. baseline: +X% (to be defined per market). - Web performance: LCP p75 < 2.5s (on realistic mobile networks), INP p75 < 200ms. - Quality: < 1% of releases with blocking bugs in production; 100% tracking coverage of critical events. - Delivery: average turnaround from brief → first LP iteration ≤ 5 working days. - Knowledge capitalization: updated templates and playbooks with inter-country reusability. ## Qualifications Required Skills : - Experienced web developer oriented towards CRO/Business, able to lead a team and drive iterative delivery. - 8-10 years of overall professional experience, with at least three years of proven experience leading and managing a team. - Proficient in vanilla JS, HTML5/CSS3, PHP, with knowledge of Memcached and API/AJAX calls. - Strong expertise in web performance optimization (network, rendering, minimal bundling). - Solid understanding of A/B testing and analytics (ideally Snowplow) with ability to interpret acquisition KPIs. - Pragmatic leadership: sets the pace, makes decisions, documents, and drives alignment. - Strong cross-functional communication, results-oriented, and highly autonomous.
