Senior Product Designer

This job is brought to you by Jobs/Redefined, the UK's leading over-50s age inclusive jobs board.

The Role
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'll 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 end-to-end, drive design strategy, and use
data, experimentation, and commercial insight to shape what we build and why.
We're an AI-first organisation. We expect you to actively use AI tools throughout your design
workflow and, critically, to lead the redesign of design workflows themselves using AI - from
research synthesis and ideation through to prototyping, testing, and design system management.
You'll bring proven experience of rebuilding design processes around AI capabilities, not just using AI
as an add-on to existing ways of working.
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: you've been involved
in designing A/B tests, interpreting results, and using data to drive iterative design
improvements.
• Deep expertise in UX research methods - you've planned and run usability testing, customer
interviews, and journey mapping, and know how to turn 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: you actively experiment with new tools, you're curious about how AI is
reshaping design, and you're excited to work in an organisation that treats AI adoption as a
core competency.
• Comfortable operating with autonomy and at pace - you can 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 - you 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.
Travel and Attendance
This role is hybrid, with a formal requirement of at least 2 days per week in our London office.
Regular in-person collaboration with Product and Engineering teams is a core part of how we work.
