About This Opportunity

We are representing a confidential digital experience agency seeking a Senior UX/UI Designer with specialized expertise in Conversion Rate Optimisation (CRO) to join their London-based team. This is a hands-on, embedded role within a dedicated CRO squad, designing premium web experiences and landing pages that maximize user engagement and drive measurable business results.

You'll be instrumental in translating user data, behavioral analytics, and strategic hypotheses into high-impact design variations and optimized user journeys.

Responsibilities

Conversion-Centered Design & Execution:

• Lead the end-to-end UX/UI design process for A/B testing, multivariate testing, landing pages, and ongoing optimization initiatives across web and mobile platforms
• Develop detailed user flows, interaction models, wireframes, and interactive, high-fidelity prototypes specifically optimized for experimentation and user validation
• Create pixel-perfect UI designs that elevate brand guidelines, utilizing persuasive design patterns, psychological triggers, and clear, conversion-focused hierarchies
• Work with and support tokenized design systems, ensuring scalability, efficiency, and consistency of components across a multi-brand environment
• Design and optimize unique, tailored user journeys for portfolio sub-brands, ensuring distinct visual identities while adhering to core design system architectures
• Focus on landing page layouts, micro-interactions, persuasive copywriting placement, and checkout/signup funnel optimization to systematically minimize friction
• Translate user feedback, testing data, and statistical results from A/B tests into actionable, iterative design recommendations
• Ensure all experiment designs are technically feasible and collaborate closely with developers during implementation, providing detailed specifications and reviewing builds

Collaboration & CRO Advocacy:

• Work closely with CRO Strategists, Web Analysts, Product Managers, and front-end Developers in a fast-paced, agile squad environment managing multiple experimentation pipelines
• Advocate for data-informed, evidence-based design decisions, presenting design concepts and experimentation rationale clearly to clients and stakeholders
• Actively contribute to and maintain conversion-oriented design libraries, templates, and documented best practices to scale optimization efforts

What We're Looking For

• Essential Portfolio: A portfolio demonstrating clear end-to-end design process, specifically highlighting how you use user insights, data, or test hypotheses to design landing pages, optimized user flows, and successful A/B test variations
• Desirable CRO Experience: Background designing for A/B testing, personalization, CRO, or landing page optimization where design decisions have been informed by user insight, performance data, or test learnings
• Tokenized Design Systems Mastery: Deep understanding of working with tokenized design systems (design tokens in Figma) to manage styling variables, thematic brand changes, and cross-platform consistency efficiently
• Multi-Brand Navigation: Proven ability to design distinct user journeys for various sub-brands, balancing brand customization with core systemic rules
• Digital Commerce & Product Context: Experience designing high-converting experiences for e-commerce, transactional websites, lead-generation pages, or digital products highly desirable
• Mastery of UX & Conversion Principles: Deep understanding of user psychology, persuasive design, usability standards, responsive layouts, and platform-specific UX/UI guidelines
• Figma & Prototyping Proficiency: Exceptional proficiency in Figma, with ability to create structured, scalable design files, component libraries, and realistic prototypes for testing
• Technical Understanding: Solid understanding of front-end capabilities (HTML, CSS, and basic JavaScript limitations) to ensure optimization designs are technically feasible and performant
• Collaboration & Agility: Strong communication skills, collaborative mindset, comfortable presenting design rationale to stakeholders and working in fast-paced agile development/testing cycles
• Accessibility & Performance: Strong understanding of web accessibility (WCAG) and page performance considerations to design fast, inclusive, and seamless experiences
