Senior UX/UI Designer:in (80–100%)

This is Adyen Adyen provides payments, data, and financial products in a single solution for customers like Meta, Uber, H&M, and Microsoft - making us the financial technology platform of choice. At Adyen, everything we do is engineered for ambition.  For our teams, we create an environment with opportunities for our people to succeed, backed by the culture and support to ensure they are enabled to truly own their careers. We are motivated individuals who tackle unique technical challenges at scale and solve them as a team. Together, we deliver innovative and ethical solutions that help businesses achieve their ambitions faster. ABOUT THE TEAM AND THE ROLE Platform Engineering enables business growth by providing the shared foundation that lets Adyen engineers autonomously build and support secure, scalable, and reliable products — from data centers and networks to deployment environments and database solutions. As Senior Service Designer for Platform Engineering, you will improve the end-to-end developer experience across internal tools, workflows, and platform capabilities. The role blends service design, UX strategy, and hands-on design consultancy. You will act as the bridge between high-level strategy and tactical execution, making Platform Engineering feel and function like a single, cohesive experience rather than ~100 disconnected products. You will start with the Developer Center — the central developer platform and launch pad for everything else — then expand to the journey across the wider developer ecosystem, which today is fragmented and inconsistent. You will work on both improving what exists and shaping what comes next. You can expect an 80/20 split as you come into Adyen, where 80% of your time and work will be in service design, and 20% could involve hands-on user experience or user interface design. At Adyen, people own their career, so while this is what you can expect initially, this role will be yours to shape. WHY THIS ROLE *     Greenfield by design. Service design as a coordinated practice does not yet exist at Adyen. You are not inheriting a playbook — you are writing it, and socializing it across PX as the example of what good looks like. *     Real scope, real impact. Your users are ~1,500 engineers. The frictions you remove and the journeys you connect translate directly into how fast Adyen can build and ship. *     A seat where decisions are made. You will influence and co-create roadmaps and priorities with engineering and product leadership — not just respond to them. *     Room to grow the craft. You will teach and share service design across the PX practice, helping other designers adopt these methods and creating a multiplier effect well beyond your own projects. WHAT YOU’LL DO Build the service ecosystem. Map and own the end-to-end service journey for Platform Engineering. You look beyond the screen to design how people, processes, and technology work together to create a seamless experience. Drive continuous improvement across systems. Create interventions that change how whole teams and systems work together, advancing the organization — not just individual features. Enable design thinking at scale. Act as a consultant to product and engineering teams, giving them the tools and methodologies to apply design to their own problem spaces. Shape AI-enabled developer experiences. Design how AI shows up in developer workflows — from discovery and self-service to troubleshooting, documentation, and automation — applying it where it creates real value and improves productivity without adding complexity. Define the strategic vision. Take ownership of broad, undefined spaces within the internal developer platform. You frame the problem and create a clear service strategy that balances user needs with technical and regulatory constraints. Consult on UX/UI excellence. Partner with product teams to ensure individual features align with the broader platform logic and meet our high bar for usability. Should be comfortable solving or unblocking UI or UX problems as they arise in teams.  Partner across the organization. Work with Product, Technology, and Data Analytics to turn complex data into actionable service blueprints and long-term roadmaps. Articulate value. Communicate service methodologies and the tangible business impact they deliver to senior stakeholders and cross-functional partners. THIS IS YOU Experience. 8+ years in design overall, including 3+ years specifically in service design, navigating complex software or hardware environments. You have a proven track record of using service design to simplify intricate workflows in SaaS or B2B products. Full-stack service design. You develop a deep, top-to-bottom understanding of the systems underlying developer touchpoints, so you can make operational improvements that matter to people and have a positive impact on developer satisfaction and retention. Systems thinking. You see the big picture. You map intricate journeys that span entire ecosystems — looking up, down, and across — ensuring consistency and logic at every touchpoint. Consulting mindset. You are comfortable as a coach and advisor, empowering other teams to make design-led decisions while holding a high bar for the final output. Exceptional communication. Standout facilitation and storytelling skills. You think about both company systems and people systems, and you build alignment across teams that don’t naturally work together. Technically fluent. Strongly tech-savvy and comfortable in technical conversations without needing to be an engineer. Ideally you’ve built complex application offerings or worked as a systems designer in an ecosystem environment. AI and innovation mindset. You have experience integrating AI tools into the end-to-end design process — leveraging AI for research, synthesis, or prototyping — and you can enable others to use these tools to work smarter and faster.    Nice to have *     Familiarity with business banking, fintech, or enterprise financial services, and comfort with data-heavy surfaces and complex financial user needs. *     International work experience.   Our Diversity, Equity and Inclusion commitments  Our unique approach is a product of our diverse perspectives.
