CRO Specialist (Maternity Cover)

About the Position

We are seeking a CRO Specialist (Maternity Cover) to join team.blue in Bratislava, Slovakia. This role involves focusing on conversion optimization across multiple brands within the team.blue portfolio.

Responsibilities

Experimentation & Execution

• Design and execute A/B tests and experiments across landing pages, funnels, forms, CTAs, and key conversion points, based on analytics data, user behavior insights, funnel analysis, and input from the Paid Media and SEO/GEO teams.
• Build experiment variants in the A/B testing tool, either by implementing directly or by coordinating with CX Integration on builds, QA, and deployment.
• Ensure proper test setup, statistical validity, sample sizing, and clean documentation of every experiment.
• Analyze results rigorously and translate findings into clear, actionable recommendations.
• Implement winning variations and ensure learnings are scaled across relevant brands.

Cross-Functional Collaboration

• Partner with Paid Media Managers and Specialists on landing page testing priorities, ensuring paid campaigns have optimized conversion paths.
• Collaborate with the Commercial, UX, and Feature teams at CEE to drive optimization for new product launches, commercial campaigns, and cross-sell.
• Represent CRO in cross-functional squads for segmentation and conversion initiatives.
• Work with Organic Growth Specialists on funnel improvements, including blog-to-conversion paths, product page optimization, and pricing page performance.
• Collaborate with Analytics to access performance data, validate experiment results, and identify high-impact testing opportunities.
• Coordinate with Campaign Managers to align experiment timelines with campaign delivery schedules.
• Brief CX Integration clearly on variant requirements, tracking needs, and QA criteria.

Analysis & Insight

• Monitor conversion performance across assigned brands and proactively identify optimization opportunities.
• Analyze user behavior using available tools (heatmaps, session recordings, funnel analysis, GA4, Bloomreach) to inform hypothesis generation.
• Build and maintain an experiment log documenting hypotheses, test designs, results, and learnings.
• Contribute to Group-wide CRO playbooks, testing frameworks, and best practice documentation.

Operational Excellence

• Maintain a consistent pipeline of experiments; testing velocity matters as much as individual test outcomes.
• Ensure all experiments meet quality standards for statistical rigor, clean implementation, and accurate tracking.
• Manage multi-brand testing workloads efficiently within sprint commitments.
• Escalate technical blockers, platform limitations, or resource constraints to the Growth Optimization Manager.

Requirements

Must-haves

• 2-3+ years of hands-on experience running A/B tests end-to-end, with a working understanding of statistics (sample size, significance, peeking, and false positives).
• Experience with an A/B testing tool such as Bloomreach (our current tool), Optimizely, VWO, Convert, or any comparable tool.
• Fluency in analytics and a behavior tool (GA4, Bloomreach, Hotjar, Clarity, or similar).
• Fluent spoken and written English, as you will work across several markets and brands. Slovak, Czech, or Hungarian is a plus.

Nice-to-haves

• HTML/CSS/JS for building variants.
• Tag management.
• Hosting/SaaS/e-commerce funnel experience.

We Offer

• Opportunity to work in a dynamic and innovative environment.
• Collaborate with a diverse and inclusive team.
• Contribute to the success of a leading digital enabler in Europe.
