Senior Product Designer

We’re looking for an exceptional Senior Product Designer to take end‑to‑end ownership of the customer experience across our two core consumer products: WorldofBooks.com (web and mobile app) and Sell Your Books (web and mobile app). This is a senior, strategic, and hands‑on role. You will be the sole designer embedded across our D2C and SYB product teams, working alongside Product Managers and Engineering teams. You won’t just be designing features – you’ll own customer journeys from acquisition and discovery through to conversion and retention, drive design strategy, and use data, experimentation, and commercial insight to shape what we build and why. We’re an AI‑first organisation. You will actively use AI tools throughout your design workflow and lead the redesign of design workflows themselves using AI, from research synthesis and ideation to prototyping, testing and design‑system management.

Main Responsibilities

• Strategy & Ownership
  • Own the end‑to‑end design strategy across D2C (WorldofBooks.com) and SYB, taking responsibility for customer journeys from acquisition and discovery through to conversion and retention.
  • Define and drive the design vision for both products, ensuring design decisions are grounded in customer insight, commercial data, and experimentation.
  • Lead the development and maintenance of design systems, UX principles, and pattern libraries that scale across both products.
• Research & Experimentation
  • Plan and run qualitative and quantitative user research, including moderated and unmoderated usability testing, customer interviews, and journey mapping to build an evidence base for design decisions.
  • Partner with Product Managers and Analysts to design, implement and analyse structured A/B tests and optimisation experiments, using results to drive measurable improvements in conversion, engagement, and revenue.
  • Conduct UX audits, identifying conversion barriers, mobile experience gaps, and opportunities for improvement across both products.
• Design Execution
  • Produce high‑quality UX and UI design from discovery and research through to high‑fidelity designs ready for engineering, across web and mobile platforms.
  • Design usable, clear, and commercially effective interfaces that balance user needs with business goals around conversion, SEO, and other key metrics.
  • Collaborate closely with Product Management and Engineering to translate insights into shippable designs and support iterative delivery.
• AI & Ways of Working
  • Lead the integration of AI tools into the design workflow end‑to‑end – from research synthesis and ideation through prototyping, implementation, testing and design‑system management.
  • Actively redesign and rebuild design processes to take advantage of AI capabilities, demonstrating measurable efficiency and quality gains, enabling our product and engineering teams.
  • Share AI best practices with the wider product and engineering teams to strengthen our AI‑first culture.
• Communication & Collaboration
  • Present design work, research findings, and recommendations clearly and persuasively to senior stakeholders.
  • Work effectively across cross‑functional teams, including Product Management, Engineering, Data, Analytics and Marketing.
  • Document customer journeys, design decisions, and experimentation outcomes clearly for the wider organisation.

Person Specification and Prior Experience

• Minimum 5 years of experience in UX and Product Design, with at least 2‑3 years operating at a Senior level with demonstrable strategic ownership.
• Significant depth in e‑commerce or high‑traffic consumer digital products – you understand the commercial impact of design decisions on conversion, revenue and customer lifetime value.
• A strong portfolio demonstrating measurable impact on conversion, engagement or commercial outcomes through design, not just visual craft.
• Proven experience leading structured experimentation programmes – designing A/B tests, interpreting results and using data to drive iterative design improvements.
• Deep expertise in UX research methods – planning and running usability testing, customer interviews and journey mapping, and turning findings into design decisions.
• Demonstrable experience using AI tools to rebuild design workflows end‑to‑end – not just using AI as an add‑on but fundamentally rethinking how design work gets done.
• An AI‑first mindset – actively experimenting with new tools, curious about how AI is reshaping design, and excited to work in an organisation that treats AI adoption as a core competency.
• Comfortable operating with autonomy and at pace – able to lead a workstream, manage ambiguity and ship work as the sole designer across multiple products.

Skills and Abilities

• Expert‑level interaction and visual design skills with deep mobile‑first and responsive design experience across web and native app platforms.
• Advanced proficiency in Figma, including component libraries and design systems.
• Strong ability to distil complex research findings and experimentation data into clear, actionable recommendations and compelling design narratives.
• Excellent visual communication and storytelling – can present work persuasively to senior stakeholders and non‑design audiences.
• Comfortable balancing high‑level strategic thinking with hands‑on pixel‑level execution.
• Knowledge of accessibility standards (e.g., WCAG 2.2) and inclusive design practices.
• Pragmatic, collaborative communicator who builds trust quickly across cross‑functional teams.
• Proficiency with AI‑assisted design and research tools, with proven ability to redesign workflows and processes around AI capabilities.
