About The Role

Senior UX Designer

Location: Hereford, England, United Kingdom

Type: Permanent

Working Pattern: Hybrid (3 Days a week onsite)

MandM is evolving how we deliver digital experiences, combining user‑centric design with product‑led ways of working. As we restructure our team and build empowered, cross‑functional squads, we are looking for a Senior UX Designer who will serve as the crucial middle ground in our design team and champion UX across the business.

You’ll set the standard for user experience, taking features and journeys from concept to launch while balancing technical feasibility and commercial viability. You will be an essential part of a collaborative team, helping to define success measures and mentor junior talent, while working alongside Product Owners and Tech Leads to deliver a measurable impact on key OKRs.

You will undertake end‑to‑end user experience design, translating complex customer problems and requirements into intuitive, accessible digital journeys. Operating within our product model, you will independently drive the design pipeline from initial ideation to production‑ready output, ensuring all solutions alleviate friction and elevate the customer experience.

While focusing on core hands‑on contribution, you will also play a key role in reviewing the work of others, maintaining consistency across our design system, and providing valuable mentorship to junior team members as our UX practice grows.

• Design Excellence & Systems – Produce strong design outputs including wireframes, user flows, low‑ and high‑fidelity prototypes, and component libraries. Uphold the design system as the single source of truth across Figma and Storybook to maintain a cohesive experience and drive scalability. Balance personal hands‑on contributions with reviewing the work of others to ensure overall quality, consistency, and alignment with brand guidelines.
• Strategy & Complex Problem Solving – Lead in solving challenging edge‑case scenarios and navigating complex user and business requirements. Facilitate workshops and design crits to align cross‑functional teams and smoothly negotiate trade‑offs between UX, business goals, and tech debt. Clearly articulate design rationale to diverse stakeholders with credibility, professionalism, and engaging storytelling.
• Evidence-Based Rationale – Champion user research, formulating and conducting usability testing that delivers clear outputs to inform data‑led decision‑making. Confidently interpret user behaviour data and analytics to ensure designs are thoroughly substantiated. Uphold accessibility standards to maintain strict compliance with WCAG 2.1 AA guidelines across all UI designs.
• Collaboration & Team Development – Collaborate closely with cross‑functional partners in product, engineering, and business stakeholders to ensure refined, scoped, and timely delivery. Partner with third parties where necessary to deliver UX/UI wireframes and validation testing. Act as a supportive mentor for junior design talent, contributing directly to our internal design culture and knowledge sharing.

We are looking for someone who meets the following:

• Core UX Experience – Demonstrated experience working as a UX / Product Designer within a fast‑paced, digital product environment, with a proven track record of handling senior‑level design complexities.
• Design Toolkit – Advanced proficiency in Figma and Adobe Creative Suite, with a strong understanding of how components translate to code (no actual coding required).
• Methodology Alignment – Practical experience working within a product model and Agile/Scrum frameworks and ceremonies is essential.
• Data & Testing Mindset – An inquisitive, data‑led mindset with proven experience preparing, executing, or analysing user research and usability testing.
• Accessibility Knowledge – Strong foundational knowledge of WCAG 2.1 AA accessibility standards and their practical application in UI design.
• Workshop Facilitation (Desirable) – Experience leading, planning, and executing design‑thinking style workshops or design crits is highly advantageous.

• Competitive Salary
• 2 days paid volunteering to support a cause you care about
• Opportunity to grow
• Staff Discounts
• Company Pension
• Generous Holiday Allowance – 5 weeks of breaks, option to buy an extra week
• Birthday Delight – Take your special day off to celebrate you
