Who we are

At Mention Me, we pride ourselves in providing end-to-end acquisition solutions to our customers through our powerful platform which combines AI‑powered referral marketing, influencer management, and multi‑channel creative performance insights.

Backed by Octopus Ventures and Eight Roads, we’ve raised $32 million in funding since 2018.

Since 2013, our award‑winning acquisition platform has driven over 9 million new customers, generating $3 billion in incremental revenue for our clients.

Today we work with clients across multiple international industries, from fashion and beauty to financial services and travel. There’s a good chance you’ve already come across us while online shopping from ASOS, PUMA, Gymshark, Charlotte Tilbury, or any other of the 500+ global brands we work with. Becoming a Mentioneer means you’ll be joining a driven team, with big plans, at a genuinely exciting time for our business.

The role

We have set an ambitious roadmap driven by a multi‑product strategy and we’re now looking for an experienced Senior Product Designer to help us take our product to the next level. Our AI‑driven platform offers powerful functionality that drives excellent results, but it needs to be simple, easy to use and accessible. We’re also rolling out additional products alongside new ways to embed AI as part of the wider experience.

Who we’re looking for

From discovery to delivery to iteration, we’re looking for someone who can embrace innovative technologies and deliver design at pace. It’s an opportunity to reimagine our user experience as we evolve our product for the AI era.

Responsibilities

• Champion a user‑centric approach to design, conducting user research, usability testing, and gathering feedback to inform product decisions and enhance the user experience
• Confidently run interviews with clients to identify pain points, for usability testing or to gather feedback on specific features
• Run and facilitate design workshops for collaborative ideation
• Work closely with the product team to translate product requirements and user needs into innovative design concepts and solutions
• Prototype at various levels of fidelity, including rapid AI prototyping
• Define and design intuitive user interactions
• Evolve and maintain the information architecture of the platform
• Work closely with Engineers, and other stakeholders, to ensure high‑quality implementation
• Make sure the product is usable by people with varying abilities
• Evolve, consolidate, and maintain our design system
• Present your solutions and communicate design rationale to internal teams, our customers, and stakeholders at all levels

We’d really like to hear from you, if you have…

• At least 5 years in a UX / UI Design and / or Product Design role delivering digital products
• Experience working in SaaS, Martech, or B2B industries
• A thorough understanding of user behaviour psychology
• Experience with HTML, CSS, responsive design, some understanding of React, as well as technical constraints and their impact
• Proficiency in current design and user testing tools such as Figma, UserTesting, and Maze, as well as emerging AI technologies
• A solid understanding of user‑centred design principles, interaction design, and information architecture
• Proven experience using and analysing data in the design process (today we’re using PostHog)
• An analytical mindset and the ability to rely on both qualitative and quantitative data to make informed decisions
• Previous experience designing for AI‑driven applications
• Strong communication, presentation, and interpersonal skills
• The ability to work in both collaborative and highly autonomous environments

What to expect after you apply

• Application
• 30‑minute call
• 1st Stage : Meet with the hiring manager
• 2nd Stage : Task interview with the wider team

After you apply, expect to hear back from us within 3 working days, regardless of the outcome. If there’s an unexpected delay, it could take a few days longer but we definitely won’t leave you hanging.

If we progress your application, you’ll be invited to arrange a 30‑minute call with one of our team members.

After the initial conversation if it’s a good match both ways, you’ll be invited to meet with the hiring manager, typically over a virtual call but we also love face to face interviews where possible.
