Senior Product Designer

What you'll do

• Own the design system that engineers and coding agents build our AI experiences from. Components, patterns, rules and guidance that read correctly to an engineer and to a coding agent, so the right choice is the default even when you're not in the room.
• Shape and ship the patterns for agentic and generative experiences. Natural language where conversation fits, generated UI where the data is dense, and agents that take on the admin, verification and sourcing around a repair while the person keeps the decisions that matter.
• Define how the product behaves when it's uncertain. When the agent acts, proposes or asks, in line with the cost of being wrong. How it shows its work, how a person corrects it, and who's right when they disagree.
• Give the product its character. How our agents speak to a repairer, their tone, when they're brief and when they explain. A personality people recognise on every surface where they meet us.
• Hold the bar across every product. Notice when the same job looks different in two products and fix it at the source, in the system rather than page by page. Measure adoption and quality, and hold teams to them.
• Work with real prototypes. Build working versions with AI tools inside our design system, test them on real data, and put them in front of repairers and suppliers.
• Pair with engineers, no hand-offs. Work directly with Product Engineers and their teams, polish the details together, and review the UI that coding agents produce from the system.
• Spend real time with customers. In the workshop, on the phone and in the product, running research alongside the Product Leads who hold the deep customer context in each region.
• Write the principles and rules. How the experience behaves on behalf of a person, written clearly enough that an engineer and a model can both follow them.

What you bring

• Senior experience, evidenced. You've been trusted to run a project end to end and can point to the user behaviour that changed because of it. Typically 5+ years designing complex software; the evidence matters more than the years.
• You've designed agentic experiences, and can show the work. Shipped at work or built seriously on your own time. Tasks, tools, autonomy, human-in-the-loop, evaluation: you've made real calls on what an agent does alone, what it proposes and what it asks, and you can tell us which of those calls were wrong.
• Systems thinking. You've contributed to or built a design system that engineers reached for without being told to, and you have a view on what a system needs to be when its heaviest user is a coding agent.
• Craft that holds up in production. Real states, real edge cases, real data. Deep fluency in interaction design, copy that carries its weight, and the visual taste to make a dense, technical tool look considered.
• Product judgement. You can take a fuzzy brief and produce the problem, the constraints and the first testable version, and you can explain a trade-off you made and who disagreed. You build to learn, and you know when your prototype is lying to you.
• Comfort working with several product teams at once, respecting that each Product Lead drives their product while bringing a view that spans all of them, and comfortable telling them when it isn't good enough yet.
• Curiosity about our customers. Professionals with high expectations, low tolerance for friction, and workflows shaped by decades of industry convention.
• Clear written, verbal and visual communication.

Nice to have

• Experience designing workflow-heavy, data-dense or technically complex B2B products.
• Marketplace, catalogue, e-commerce or supply chain domains. Automotive is a bonus, not a requirement.
• High-growth startup and scale-up environments.
• Experience working in a global, distributed design team.

We're not looking for a designer whose strength is producing a hundred screens in a traditional SaaS model, or one who is apprehensive about AI. If half the work makes you nervous, this isn't the role.

How we build

We're an AI research company and we build like one. In discovery mode, anyone, designers included, can use Claude Code to build a working version inside our design system, run it against real data, and show a customer the feature with their own jobs in flight. In scale mode, engineering rebuilds what's proven. We don't ship prototype code to production; we use it to decide what production should be. Designers work in both.
