Our client, a leading global healthcare group, is developing a suite of advanced digital and AI-powered products to empower its internal teams.
We are looking for a Senior Product Designer for a strategic, transversal mission. In this assigment, you will bridge the cross-product experience strategy into shared design foundations, reusable patterns, and seamlessly connected user journeys. The objective is not merely to harmonize visual interfaces, but to fundamentally design how products interact, communicate, and work better together.
Key Responsibilities
1. Cross-Product Experience Design
Map complex user journeys across multiple tools to identify friction points and inconsistencies.
Design cohesive, end-to-end experiences that allow users to transition effortlessly between products.
Establish shared UX/UI patterns for onboarding, global navigation, cross-app notifications, and core workflows.
2. Experience Foundations & Design Systems
Audit existing UX/UI patterns and UI components across the product ecosystem.
Reuse, adapt, and scale design foundations while creating modular, conversational, and multi-product patterns.
Partner closely with engineering to guarantee technical feasibility, high accessibility standards (WCAG), and responsive adaptations (including light/dark mode).
3. Research, Discovery & Collaboration
Collaborate closely with UX researchers to validate cross-product hypotheses and uncover common user needs.
Partner with Product Managers, Engineering Leads, and Data Leads to align design initiatives with broader technical and business roadmaps.
Facilitate co-creation workshops, design critiques, and alignment sessions to prioritize strategic design efforts.
4. AI-Powered & Emerging Experiences
Seamlessly integrate conversational AI and agentic capabilities across user touchpoints.
Design human-in-the-loop interactions anchored in transparency, user trust, safety, and control.
Explore innovative interaction paradigms, including proactive insights, contextual side panels, and shared cross-product workspaces.
Key Deliverables of the Initial Mission
Ecosystem UX/UI Audit: A consolidated analysis of current design patterns, gaps, and integration opportunities across the portfolio.
Experience Foundations Roadmap: A prioritized framework of experience foundations, starting with shared user journeys.
Prototypes & Proposals: High-fidelity UX/UI concepts and interactive prototypes demonstrating cross-product continuity.
Cross-Functional Alignment: Shared documentation, reusable pattern libraries, and buy-in across design, product, and engineering teams.
Integration Plan: A practical rollout framework to embed shared design foundations directly into individual product roadmaps.
Profile & Qualifications
Experience: Proven track record as a Senior Product Designer designing complex enterprise SaaS platforms, B2B tools, or multi-product digital ecosystems.
Design Craft & Systems Thinking: Outstanding UX and interaction design skills combined with sharp UI craftsmanship. Demonstrated ability to connect micro-interactions to holistic, systemic architectures.
Design Systems: Solid experience building, maintaining, and scaling design systems and multi-brand/multi-product pattern libraries.
AI & Innovation: Hands-on experience with AI-powered features, conversational interfaces, or agentic experiences is strongly preferred.
Tooling: Advanced mastery of Figma as well as modern AI-assisted design and prototyping workflows.
Mindset: Strong strategic thinker comfortable with ambiguity, autonomous, and capable of driving alignment across multidisciplinary stakeholders.
