Category: Product Design / UX/UI Design

Date Posted: January 12, 2026

Experience Level: Senior (7+ years)

Remote Status: Hybrid (3 days on-site, 2 days remote)

🚀 Role Summary

• This senior freelance Product Designer role focuses on complex business applications within a global leader in the consumer goods sector, requiring expertise in designing for industrial organizations and business-oriented systems.

• The position involves end-to-end product design responsibilities, from initial discovery and ideation through to detailed UX/UI delivery, for two critical applications.

• A key aspect of the role is driving the development of a new product portfolio management application and enhancing an existing product lifecycle management application, directly impacting sales force reactivity and operational efficiency.

• The ideal candidate will leverage a strong understanding of user experience principles, interface design, and a collaborative design process, integrating with existing design systems and tools like Figma.

📝 Enhancement Note: This role is specifically for a freelance contractor with a minimum 2-year commitment, emphasizing a need for immediate impact and long-term project ownership. The focus on "complex business applications" and "industrial organizations" suggests a need for a designer comfortable with intricate workflows, regulatory compliance, and B2B user needs, rather than consumer-facing products.

📈 Primary Responsibilities

• Discovery & Needs Assessment: Conduct comprehensive needs discovery and user research with sales teams and internal stakeholders to understand business requirements, market positioning, and regulatory complexities for product portfolio and lifecycle management.

• Ideation & Solutioning: Facilitate and participate in ideation workshops to generate innovative solutions that address user needs and business objectives, considering country-specific catalog variations, regulatory changes, and market evolutions.

• UX/UI Design Delivery: Create detailed user journeys, wireframes, interactive prototypes, and final UI screens for both new application development and feature enhancements, ensuring adherence to the existing design system and brand guidelines.

• Cross-functional Collaboration: Work closely with Product Managers, Lead UI Designers, Head of Design, and end-users (Sales, logistics, etc.) to ensure design alignment, gather feedback, and drive project forward.

• Product Lifecycle Management Enhancement: Contribute to the roadmap of an existing application by designing new features and improvements, extending its functionality to cover additional product categories and user workflows.

• Design System Utilization & Evolution: Actively use and contribute to the existing Figma-based design system, ensuring consistency and scalability across the applications.

• Autonomy & Project Ownership: Proactively own and drive product design initiatives from conception to completion, especially for the new, less-defined application, demonstrating strong initiative and problem-solving skills.

📝 Enhancement Note: The responsibilities highlight a "full role from end to end" for one application, including UI, and a more focused UX role for the second, with the Lead UI Designer handling final screens. This distinction is crucial for candidates to understand the scope of their UI contribution. The emphasis on "carrying and advancing a product that is still fuzzy" points to a need for strong self-direction and ambiguity tolerance.
