As a reflection of our current needs and planned growth we are very pleased to offer a new opportunity to join our dedicated team as a Senior UI/UX Designer.

Job Description:

We are looking for a Senior UI/UX Designer with 4-6 years of experience to lead and drive the design of intuitive and engaging user experiences across our product portfolio. As a Senior UI/UX Designer, you will be vital in shaping the user experience strategy, mentoring junior designers, and collaborating with cross-functional teams to deliver top-notch digital products.

Key Responsibilities:

• Lead the end-to-end UX design process, from research and concept development to final implementation.

• Conduct and synthesize user research to inform design decisions and identify user needs.

• Develop and iterate on user personas, user journeys, wireframes, prototypes, and high-fidelity designs.

• Collaborate closely with product managers, developers, and other stakeholders to ensure design feasibility and alignment with business goals.

• Conduct usability and A/B testing to validate design solutions and make data-driven improvements.

• Mentor and guide junior UX designers, providing feedback and ensuring adherence to design best practices.

• Advocate for user-centered design principles and contribute to continuously improving design processes and methodologies.

• Stay informed on industry trends, emerging technologies, and best practices in UX design.

• Present and communicate design concepts and strategies to stakeholders at all levels of the organization.

• Establish and maintain a scalable design system, including defining the token architecture (color, typography, spacing, elevation, and motion tokens) and building a library of reusable components, patterns, and templates for web and mobile applications.

• Craft high-quality visual designs that reflect a strong command of typography, color theory, layout, iconography, and motion - demonstrating a clear point of view on what "good" looks like in modern digital product design.

• Partner with engineering to ensure design tokens are correctly implemented and that the design system is adopted consistently across all product surfaces, maintaining design-to-code fidelity.

Qualifications:

• 4-6 years of experience in UX design, with a strong portfolio demonstrating expertise in creating user-centered designs for web and mobile applications.

• Proficiency in design tools such as Figma.

• Deep understanding of UX principles, methodologies, and best practices.

• Experience leading UX projects and collaborating with cross-functional teams.

• Strong analytical skills and the ability to translate complex user needs into simple, elegant design solutions.

• Excellent communication, presentation, and storytelling skills.

• Experience with usability testing, A/B testing, and data-driven design.

• Knowledge of front-end development principles (HTML/CSS) is a plus.

• Ability to manage multiple projects and deliver high-quality work on time.

• Proven experience building or significantly contributing to a design system, with hands-on work defining token structures (primitive and semantic tokens) and authoring component documentation.

• Strong visual design sensibility with a portfolio that demonstrates mastery of composition, typographic hierarchy, color systems, and a modern aesthetic - not just UX flows and wireframes.

• Familiarity with design token tooling and workflows (e.g. Tokens Studio, Style Dictionary, or equivalent) and experience collaborating with engineers on token implementation in a codebase is a plus.

Core Competencies:

• Design Leadership: Ability to lead design projects, mentor junior designers, and drive the UX process from concept to execution.

• Advanced User Research: Expertise in conducting and synthesizing complex user research to inform design decisions and improve user experience.

• Prototyping & Usability Testing: Proficiency in creating high-fidelity prototypes and conducting usability tests to validate design solutions.

• Strategic Thinking: The ability to align design work with business goals ensures user experience contributes to overall product success.

• Communication & Presentation: Strong skills in presenting design concepts and rationale to stakeholders and advocating for user-centered design.

• Design Systems Expertise: Deep understanding of design system architecture - from establishing token hierarchies (primitive, semantic, and component-level) to building and governing a shared library of components, patterns, and templates that scale across products and platforms.

• Visual Design Craft: A refined eye for visual quality, with the ability to set a high bar for UI aesthetics - including typography, color, spacing, and interaction design - grounded in an awareness of modern design trends and what distinguishes polished, production-ready interfaces.
