• Agile Integration: Seamlessly integrate into an agile product team, participating in rituals and collaborating closely with Product Owners, Business Analysts, Developers, and UX Designers.

📝 Enhancement Note: While the job title is "UI Designer Senior," the description emphasizes a highly operational and production-oriented role. This suggests a focus on execution and delivery of UI assets rather than high-level strategic design or team leadership, though senior experience is required. The context of a banking and digital environment implies a need for robust, user-friendly, and secure interfaces.

📈 Primary Responsibilities

• UI Design & Production:

  • Actively contribute to UI production, designing intuitive and visually appealing mobile application interfaces.
  • Create high-fidelity mockups and responsive design variations in close collaboration with UX Designers.
  • Define and implement visual styles, UI components, micro-interactions, and animations.

• Design System Management:

  • Apply and enhance the existing Design System, ensuring its integrity and usability.
  • Guarantee graphical consistency and adherence to UI standards across all product touchpoints.
  • Document UI patterns, components, and their usage within the Design System.

• Agile Collaboration:

  • Integrate into an agile product team, participating actively in Scrum ceremonies (e.g., sprint planning, daily stand-ups, retrospectives).
  • Foster strong collaborative relationships with Product Owners (POs), Business Analysts (BAs), Developers, and UX Designers.

• Technical Constraint Awareness:

  • Understand and design within the technical constraints of mobile platforms (iOS/Android).

  • Advocate for and implement accessibility standards (e.g., WCAG) in UI designs.

📝 Enhancement Note: The responsibilities clearly indicate a hands-on role focused on the execution of UI design. The emphasis on "production UI" and "high-fidelity mockups" points to a designer who is comfortable with detailed execution and delivering tangible design assets. The need to "apply and enrich the Design System" suggests the candidate will work with an established system, potentially contributing to its growth and maintenance.

🎓 Skills & Qualifications

Education: While not explicitly stated, a Bachelor's or Master's degree in Graphic Design, Interaction Design, Human-Computer Interaction, or a related field is typically expected for senior roles. Equivalent professional experience will also be considered.

• Experience in Banking/Finance Sector: Familiarity with the specific design considerations and user expectations within the financial services industry.

📝 Enhancement Note: The "Must-have" list is very specific, with Figma mastery being non-negotiable. The "Senior" title, coupled with the 5-10 year experience range, suggests a need for a designer who can operate independently, mentor junior designers (though not explicitly stated), and contribute significantly to the product's visual direction. The emphasis on "operational" and "production" means candidates should be ready to demonstrate a portfolio of delivered UI work.
