Senior Product Designer in London

Working with employers, we provide a financial wellbeing platform as an employee benefit, helping employees to understand their money better, get out of debt faster and save for their future. We already have a reach of circa 4,000,000 employees through our relationships with over 500 of the largest employers in the UK. By improving employee financial wellbeing, we have a very real and meaningful impact on people’s lives. We remove the stress and worry associated with financial difficulties by dramatically reducing the interest rates employees pay on their personal debt, and provide them with the tools needed to start saving sooner and be more financially secure.

Your role in our mission: This role exists to solve problems where the answer isn’t known yet. You’ll design entirely new product experiences that help people move from repaying debt to building savings, a behavioural shift that most fintech companies have failed to crack. You’ll drive the end-to-end design process from early-stage user research through to pixel‑perfect handoff, working alongside Product Managers and Engineers in a small, high-impact team. If you want your design work to measurably improve people’s financial lives, this is one of the most meaningful roles in UK fintech right now.

What you’ll do:

• Lead the design of new product experiences that increase user engagement with savings and financial wellbeing tools.
• Own the UX strategy for transitioning loan customers into savings products—a critical commercial and social impact challenge.
• Conduct and synthesise user research to identify unmet needs, then translate insights into testable concepts and validated designs.
• Facilitate ideation sessions with cross‑functional teams, bringing structure and creativity to ambiguous problem spaces.
• Produce high‑fidelity designs and interactive prototypes in Figma, working within and evolving our design system.
• Partner closely with Engineers and Product Managers to ensure designs are built faithfully and shipped with quality.
• Define and track experience metrics (task completion, adoption, NPS) to measure the real‑world impact of your design decisions.
• Represent Product Design across the business, articulating the team’s approach, rationale, and value to stakeholders.
• Contribute to the growth of the design practice through mentoring, critique sessions, and process improvement.

What Success Looks Like:

• First 30 days: You’ve immersed yourself in user research, understood the product landscape, and built strong working relationships with your squad and the existing Product Design team.
• First 90 days: You’ve shipped your first design iteration and are running usability tests. You’re contributing meaningfully to design critiques and squad planning.
• First 6 months: You’ve delivered a measurable improvement in a key experience metric. You’re recognised as a trusted design partner across product and engineering.

About You:

• Significant experience (typically 5+ years) designing consumer‑facing digital products, with a portfolio that demonstrates world‑class craft.
• Deep empathy for users—you instinctively seek to understand people’s real problems before jumping to solutions.
• Strong commercial awareness: you understand that great design drives business outcomes, not just user delight.
• Expertise in Figma and confidence working within or building design systems.
• Excellent problem‑solving skills with the ability to articulate ‘why’ behind every design decision, not just ‘what’.
• Experience conducting user research (interviews, usability testing, surveys) and synthesising findings into actionable insights.
• A collaborative mindset—you thrive when working closely with engineers, product managers, and stakeholders.
• Comfort with ambiguity and the ability to adapt your process to the situation, knowing that ‘perfect’ is context‑dependent.
• A genuine passion for social impact and building products that make a meaningful difference to people’s lives.

Nice to Have:

• Experience designing for both Android and iOS, with an understanding of platform‑specific patterns.
• Familiarity with accessibility standards (WCAG) and inclusive design principles.
• Experience with research and testing tools such as Maze, Hotjar, or UserTesting.
• A passion for coaching or mentoring other designers.
• Some coding ability (HTML/CSS or prototyping in code)—enough to speak engineers’ language fluently.

Who you are:

• Fearless, and able to make the impossible possible.
• Responsible, and want to help build a business that delivers a meaningful difference to society.
• Dedicated and want to commit to an exciting journey even through the highs and lows.
• Empathetic and truly care about every colleague and customer.
• United, because you understand we achieve more when we work as a team.
• Humble, and take feedback as a way to continuously improve.

What do you get for all your hard work?

• 25 days holiday with an additional day off for every year of service up to 30 days and an extra day off on your birthday.
• Hybrid working arrangements so you can work from the office and from home with a budget to help you get set up.
• Generous company benefits to include pension and life assurance and an annual allowance to spend on medical insurance, health cash plan, denplan, gym memberships.
• Enhanced policies that are family and pet friendly, to include company sick pay and peternity leave.
• Great career development in a fast paced environment.
• Regular company socials (post covid, although we’ve got quite good at virtual ones too!).
• Volunteer days as part of our CSR program.
• More great perks to include weekly snacks, tuckshop, cycle to work, help to save and much more!

The typical interview process:

• Phone call with our Talent Manager - 20 mins.
• Video interview with Hiring Manager - 30 mins (Please note we would like to review your portfolio ahead of this stage).
• Final stage - An in-person session involving a practical Case Study and meetings with the Hiring Manager, Head of Department, and the wider team to assess cultural fit and problem‑solving abilities - 90 mins.

We’re looking for people that will get stuck in and make a difference. We have a great collaborative, entrepreneurial team and are passionate about what we do. If you want to join a team that is changing people’s lives for the better then we’d love to hear from you.
