Senior UX Designer - Map Visualisation

TomTom's map is seen by millions of people every day - in dashboards, on phones, and across partner products worldwide. As a Senior UX Designer on the Map Visualisation team, you will shape how our 2D and 3D geospatial data is designed, styled and delivered across TomTom's product portfolio. You'll spend your days crafting multi-zoom map experiences, working with spatial data and collaborating closely with engineers and product managers to turn cartographic intent into production-ready map styles. You'll need to be as comfortable discussing label collision and style-layer specifications with engineers as you are refining colour palettes and visual hierarchy. This is a product role first. You'll be embedded in a cross-functional team that ships map rendering, map styles and SDKs used by other TomTom products and by the customers who build on our platform. You'll take part in the whole development lifecycle, from discovery and solution design through pull requests to release. Your product judgement, and your ability to bring people with competing priorities to a clear decision, matter here as much as your cartographic craft. AI is part of how we work. We expect you to use it to explore, prototype and ship faster, to know where it falls short, and to help shape map experiences in products where AI is part of the experience itself. What You'll Do • Design Compelling Map Experiences Create and refine 2D and 3D map visualisations from concept through production delivery. Own the end-to-end cartographic design process - from data exploration and sketching through to style implementation, QA and iteration across zoom levels, regions and use cases. • Maintain and Evolve Core Map Styles Enhance TomTom's core map styles, ensuring consistency, readability and visual quality across platforms, screen densities and global markets. Balance aesthetic ambition with rendering performance and data constraints. • Work as Part of the Product Team Work day-to-day alongside software engineers and product managers building TomTom's map data structures, renderers and SDKs. Take part in planning, refinement and reviews, provide design specifications engineers can act on, and review visual output during development and before release. • Make and Own Trade-offs Help decide what ships, when and at what quality. Weigh visual fidelity against render budget, memory and frame rate on automotive and mobile hardware, customer requests against platform consistency, and scope against release dates. Reach a decision with the people who own the product, record it and see it through. • Contribute to Renderer and Tooling Requirements Provide detailed input on the data and rendering capabilities needed to achieve design goals. Define requirements for internal cartographic authoring tools and identify workflow improvements that raise the team's output quality and speed. • Bring AI into the Design Workflow Use AI to shorten the loop from idea to rendered map: generating and editing style-spec JSON, scripting data exploration, and building interactive prototypes on real data instead of static frames. Turn what works into shared workflows the team can reuse, and help define how we check AI-generated output for cartographic quality. • Design for AI-Driven Map Experiences Contribute to how the map responds when the request comes from an AI system rather than a tap, for example in GeoAI answers, conversational search or agent-generated routes. Work out how the map shows what the AI found, how confident it is and when it is wrong. • Inform Decisions with Research and Data Participate in user research, customer conversations and competitive benchmarking. Use insights to ground design decisions and advocate for improvements that address real user needs. • Support the De
