Date Posted: 2026-05-05

Experience Level: 5-10 Years

Remote Status: Fully Remote

🚀 Role Summary

• Lead the design and evolution of Design Systems within Figma, focusing on creating reusable components, design tokens, and managing variants and states for digital products.

• Develop intuitive and visually appealing user interfaces for both web and mobile applications, ensuring a consistent and high-quality user experience.

• Collaborate closely with cross-functional teams, including Front-end Developers, Product Managers, and Business stakeholders, to translate requirements into effective design solutions.

• Champion accessibility standards (WCAG) throughout the design process, ensuring digital products are usable by a diverse audience.

• Drive the documentation and maintenance of design system guidelines, promoting best practices and efficient design workflows across the organization.

📝 Enhancement Note: This role is specifically for a Senior UX/UI Designer with a strong emphasis on Design Systems, indicating a need for a candidate who can not only design interfaces but also architect and maintain a scalable design language. The freelance and part-time nature (media jornada) suggests a project-based engagement, likely requiring significant autonomy and self-management. The company's IT focus implies a need for understanding technical constraints and working closely with development teams.

📈 Primary Responsibilities

• Design user interfaces for web and mobile applications, focusing on user-centered design principles and best practices.

• Architect, create, and maintain a comprehensive Design System in Figma, including the definition of design tokens (color, typography, spacing, etc.), reusable components, and their various states and variants.

• Develop detailed documentation for the Design System, ensuring clarity and ease of adoption for all stakeholders.

• Collaborate effectively with Front-end developers to ensure accurate implementation of designs and Design System components.

• Work closely with Product and Business teams to understand project requirements, user needs, and business objectives, translating them into design solutions.

• Conduct design validation and reviews before development handoff, ensuring designs meet quality and usability standards.

• Integrate accessibility standards (WCAG) into all design outputs, advocating for inclusive design practices.

• Contribute to the continuous improvement of design processes and workflows within the team.

📝 Enhancement Note: The mention of "media jornada" (half-day) for a "Senior" role with over 5 years of experience and Design System responsibilities suggests a focused project engagement rather than a full-time, ongoing operational role. The primary responsibilities highlight a blend of hands-on design execution and strategic system design, requiring a candidate who can operate independently and deliver tangible design assets and system components.
