Senior/StaffProductDesigner

ABOUT THE ROLE A well-funded B2B SaaS company in the industrial procurement space is looking for a Senior / Staff Product Designer to define how agentic AI capabilities come to life in a product used daily by non-technical procurement professionals. You will join a small, high-craft design team working closely with product managers, engineers, and domain experts to make AI feel natural, trustworthy, and genuinely useful — not just powerful on paper. This is a high-impact role: clear, reliable design determines whether sophisticated AI features are adopted and whether customers realise measurable savings in their procurement operations. WHAT YOU'LL DO - Define how agentic capabilities present in the app — from conveying "the agent is working" to surfacing what it found and recommending next steps. - Design interaction patterns where AI and human judgment collaborate, not compete. - Produce short-horizon vision work (3–6 months) as prototypes and tangible artifacts to align and guide the team. - Raise product craft and coherence as engineering velocity and feature output increase. - Work directly in code for last-mile polish — check out PRs and tweak interactions before shipping. - Collaborate with product managers, engineers, and procurement domain experts to translate complex workflows into usable, delightful experiences. - Define and maintain design systems and component libraries to ensure consistency at scale. - Conduct user research and usability testing to inform product decisions. WHAT WE'RE LOOKING FOR - Portfolio: Strong track record of shipped product design work, ideally in B2B SaaS, complex workflows, or data-heavy / AI-driven products. - Breadth: Solid capabilities across visual design, interaction design, product thinking, and code-based prototyping — a "block-shaped" designer rather than a single-specialty T-shape. - Prototyping: Practical experience building runnable prototypes beyond Figma that communicate intent and interactive behaviour. - AI desig
