This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a User Interface (UI) Designer based in Brazil.
We are looking for a Senior UI Designer to take ownership of website design and implementation quality across desktop, tablet, and mobile experiences.
You will transform business and content objectives into intuitive, visually engaging, and responsive website interfaces.
Beyond creating mockups, you will oversee the design process from initial concepts and prototyping through developer coordination, implementation, and final quality assurance.
Working closely with content, graphic design, and development teams, you will ensure that approved designs are accurately translated into finished web experiences.
You will also identify usability and visual improvements, maintain consistent design standards, and help refine the website's overall presentation.
Strong communication, attention to detail, and the ability to coordinate revisions across teams will be essential to your success.
This is a part-time, remote contractor opportunity for an experienced professional who enjoys combining creative design skills with hands-on implementation oversight.
As UI Designer, you will manage the complete website design lifecycle, ensuring that every interface is visually consistent, responsive, user-friendly, and accurately implemented. Your responsibilities will include:
Design and improve website interfaces across desktop, tablet, and mobile devices.
Create wireframes, mockups, prototypes, and high-fidelity UI designs for new and existing website pages.
Develop responsive layouts that deliver consistent and intuitive experiences across different screen sizes.
Create and maintain reusable UI components, design patterns, and website design standards.
Ensure that designs align with visual identity, content strategy, usability objectives, and business requirements.
Collaborate with developers to communicate approved designs, layouts, interactions, and responsive specifications.
Provide clear design documentation, references, assets, and implementation instructions.
Coordinate with developers throughout implementation, clarify requirements, identify discrepancies, and follow up on necessary revisions.
Act as the primary design point of contact between marketing and development teams.
Conduct visual and functional quality assurance of website pages before final approval.
Test implemented designs across desktop, tablet, and mobile screen sizes.
Identify and document issues related to spacing, typography, layout, responsiveness, visual consistency, functionality, and usability.
Coordinate corrective actions with developers and perform follow-up testing to verify that issues have been resolved.
Ensure that final website pages closely match approved designs and maintain consistent visual quality.
Collaborate with content teams on content structure, hierarchy, placement, and calls-to-action.
Recommend content presentation improvements when copy affects readability, layout, or user experience.
Make minor content edits when appropriate to improve clarity, readability, and visual presentation.
Work with graphic designers to ensure imagery, icons, and other visual assets integrate effectively into website interfaces.
Present design concepts and explain recommendations to stakeholders, supporting decisions with usability principles and business objectives.
Incorporate feedback while maintaining design consistency and quality.
Review existing website pages and identify opportunities to improve usability, responsiveness, and visual presentation.
Help maintain and evolve website style guides, design systems, and reusable component libraries.
