Category: UX/UI Design & Product Experience

Date Posted: May 22, 2026

Experience Level: Senior (5-10 years)

Remote Status: Hybrid

🚀 Role Summary

• Lead end-to-end UX design initiatives for a major global technology client's large-scale subscription service, ensuring cohesive and human-centered digital experiences.

• Translate complex business and product goals into clear UX strategies, defining user flows, interaction patterns, and experience structures with a strong emphasis on measurable business outcomes like revenue and retention.

• Collaborate closely with cross-functional teams, including UI designers, project managers, and US-based stakeholders, to ensure design quality, consistency, and timely delivery.

• Contribute to and leverage existing design systems and pattern libraries to ensure scalability and maintainability across multiple initiatives.

📝 Enhancement Note: While the primary focus is UX Design, the role's emphasis on tying design decisions to business outcomes (revenue, conversion, retention) and working on a subscription service indicates a strong need for understanding GTM (Go-To-Market) principles and their impact on user experience, particularly within a SaaS or consumer services context. This role is critical in bridging product strategy with user satisfaction and commercial success.

📈 Primary Responsibilities

• Own the complete UX design lifecycle for multiple digital initiatives, from initial problem framing and research through to the final definition of user experiences and touchpoints.

• Develop detailed user flows, interaction models, and information architecture that are consistent with the broader product ecosystem and existing design patterns.

• Articulate UX recommendations by framing them within the context of key business metrics such as revenue generation, customer retention, conversion rates, and customer lifetime value.

• Effectively translate product and business objectives into robust UX strategies, clearly communicating the rationale and impact of design decisions to all stakeholders, including non-designers.

• Foster strong collaborative relationships with UX and UI designers to maintain design quality and consistency, and work with Project Managers to prioritize tasks and manage delivery timelines.

• Create and maintain high-fidelity UX artifacts, including detailed flows, wireframes, prototypes, and interaction specifications, ensuring designs are production-ready for UI and development teams.

• Actively participate in and contribute to the evolution of Nacar's design systems and pattern libraries, promoting consistency and scalability across all projects.

• Conduct user research and usability testing to gather insights and validate design solutions, integrating feedback to refine the user experience.

📝 Enhancement Note: The prompt emphasizes "end-to-end UX design" and "ownership" of initiatives. This suggests the Senior UX Designer will be responsible for strategic definition, not just execution. They will need to influence product direction and build strong business cases for design investments, aligning closely with revenue operations and product management.
