• Collaborate closely with product managers, developers, and other collaborators to ensure design solutions are implemented efficiently and meet technical and business requirements. You will be the key point of contact for design feedback and iteration.
• Build high-quality UI/UX design deliverables, including wireframes, prototypes, visual designs, and interaction patterns. Ensure designs are both visually compelling and user-friendly.
• Share your expertise in design methodologies with junior designers and the broader team. Foster a culture of learning and growth by providing mentorship and guidance.

• Proficiency in design tools like Figma, Sketch, Adobe XD, or similar, with a solid understanding of design systems and how to implement and maintain them effectively.
• Experience working in agile environments and collaborating with cross-functional teams, including product managers and developers.
• Strong understanding of user research methods and the ability to translate research insights into actionable design decisions.
• A deep understanding of design principles, such as typography, color theory, and layout, with the ability to balance aesthetic appeal and functionality.
• Excellent communication skills, with the ability to present and articulate design decisions to both technical and non-technical collaborators.
• Experience in crafting and maintaining design systems for scalable, consistent, and high-quality user interfaces.
  
  

Nice To Have

• Knowledge of front-end development (HTML, CSS, JavaScript) and how designs translate into code.
• Familiarity with data visualization tools like Power BI or similar dashboards, ensuring intuitive and user-friendly reporting interfaces.
