About the Role
We're building the next generation of our Payments-as-a-Service API platform – an intelligent, self-serve ecosystem that empowers financial professionals and technology teams to discover, scope, build and integrate payment solutions autonomously.
We're looking for a Senior Product Designer to lead the end-to-end design of this platform – from discovery and scoping flows to onboarding and growth optimisation. You'll shape how customers experience our products digitally, whether through self-serve or via enterprise channels.
While a core focus of this role will be our PaaS platform, you'll also help us optimise our broader domestic payments product portfolio, ensuring consistent, best-in-class customer experiences across the ecosystem.
This is a unique opportunity to define customer-focused, product-led growth within a leading financial services organisation – combining UX craft, growth experimentation, and data-driven design to create seamless, scalable customer journeys.
You'll be a core member of the product team – working alongside Product Managers and Engineers – and share accountability for success metrics such as activation, onboarding completion, and customer satisfaction.
What You'll Do
Design the end-to-end customer experience for our Payments-as-a-Service API platform – across evaluation, scoping, and onboarding
Develop user journeys that enable business and technical users to self-serve with clarity
Create elegant, functional designs for developer-focused experiences like API documentation, integration guides and onboarding flows
Lead customer journey mapping and funnel analysis to identify opportunities for growth and conversion optimisation
Partner with Product, Engineering, Marketing, and Sales to translate complex concepts into intuitive experiences
Support the creation of sales enablement and product marketing materials (e.g. product visuals, digital assets, pitch decks) to articulate the platform's value
Use data, testing, and experimentation to optimise funnel performance, engagement, and onboarding completion rates
Collaborate with AI teams to design AI-assisted onboarding and support
Use interactive prototyping to explore ideas, communicate concepts internally and validate assumptions early with users
Build a continuous user-testing cadence – incorporating feedback rapidly to refine solutions
What You'll Bring
Proven experience designing B2B or platform experiences – ideally in fintech or software
Expertise in funnel analysis, growth design, and conversion optimisation
Strength in interaction design, information architecture, and visual composition
Experience with customer journey mapping, experience design and usability testing
Proficiency in modern design tools like Figma
Ability to translate technical concepts into accessible and compelling design
Understanding of user psychology, experimentation, and A/B testing
Comfort working closely with Product Management, Engineering, Sales, and Marketing
Experience creating designs that adhere to compliance requirements
Desirable Skills
Experience in API platform UX or developer experience (DX) design
Familiarity with omnichannel experience design – integrating digital, sales, and service touchpoints
Understanding of SEO, content strategy and how they influence product discovery
Strong communication skills and ability to present design rationale clearly
Experience designing or supporting AI-driven experiences
You'll Thrive if You...
Love designing for complex systems and multi-persona journeys
Are motivated by data, experimentation, and measurable impact
Enjoy translating technical depth into simple, elegant experiences
Are equally comfortable designing for growth and delight
