Deel wants to go further and build the system that lets AI build the products. Humans set the taste, the guardrails and the standards it works within. That system is your product. You build what AI generates against: the design system and component architecture, the generation and agent workflows, the quality gates that keep output production-ready, and the feedback loops that keep it all visible to the team. You stay hands-on as a designer, because the quickest way to prove the system works is to ship real interfaces on top of it. This is a senior individual contributor role in Product Design. You split your time between Figma and a code editor in roughly equal measure. You work directly with design leadership to drive AI adoption across the whole design organisation, and you sit in a cross-functional team with Engineering and Product. What you are expected to do: Build the system Architect the design system, tokens and components as the substrate AI generates against. Design prompt libraries, patterns and agent workflows that turn design intent into production-ready UI with minimal human assembly. Prove it by designing Stay a practising designer. Explore concepts quickly and design real interfaces. Prototype in production front-end code. You are the first and toughest test of whether the system produces excellent, shippable work. Own quality, guardrails and evals Define production-readiness criteria for AI-generated UI. Set design-to-code fidelity benchmarks, regression safeguards and evaluation methods that keep AI output honest. Speed must not cost craft. Drive the AI workflow across the design org Work with design leadership to maintain, evolve and roll out the AI-native workflow across the whole design organisation, not only your own work. Treat it as an ongoing responsibility. Drive adoption, keep standards current as tools change, and embed the workflow across teams so it never depends on one person. Work across functions Collaborate closely with Engineering, Product and design-system contributors. You complement engineering and do not replace it. Keep the system
