Senior Product Designer - AI Products

Senior Design Role Partly's product teams are organised around a product, each led by a Product Lead (Principal Product Manager) with a Product Engineer and a mix of engineers. Design is not embedded in those teams. We're building a global design team that works across all of our products and is focused on three things: the design system everything is built from, coherence across the whole product family, and the quality of the experience wherever a repairer or supplier meets us. Our customers range from repairers and parts admins in a single independent workshop to multi-billion-dollar repair groups, and the suppliers who provide their parts. The team exists to drive adoption and stickiness through experiences that feel magical, in a way that works for our customers. We work collaboratively with the Product Leads who drive their products. This is a senior design role for someone with incredible judgement and hands-on experience with AI surfaces and experiences. You lead with design: problem framing, systems thinking, interaction and craft. And you make things real, with working prototypes built inside our design system. You won't sit in a product team's backlog. Product Leads own their products and what ships. You own the principles, patterns and system they build from, and you set your own agenda for where those need to go next. When something ships below the bar, you're the one who says so. This role is based in one of our offices: Auckland or Christchurch in New Zealand, London in the UK, or Austin, Texas in the US. The design team works across all of them. 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.
