Role Overview
We are seeking a Senior UX Designer to transform business requirements into tangible designs, wireframes, and user experiences that clients can validate and delivery teams can build from. At Teifi, the Senior UX Designer operates as a shared resource across multiple delivery pods, working closely with Business Analysts, Solutions Analysts, and developers to ensure every client-facing experience is intuitive, on-brand, and accessible. This role owns the design lifecycle from initial wireframes through to high-fidelity mockups and client sign-off.
Key Responsibilities
Discovery & User Flows
- Participate in discovery sessions to understand the client's business context, user needs, and design constraints
- Conduct usability audits of existing client experiences to identify UX issues and opportunities before redesigning
- Map end-to-end user journeys,flows and key interactions the interface must support, working from requirements gathered by the BA and Solutions Analyst
- Develop sitemaps and information architecture to ensure logical navigation and content structure
- Produce low-fidelity wireframes of key screens and workflows for early client review before higher-fidelity design or build begins
Design & Mockups
- Create polished, high-fidelity mockups representing the final look and feel of the solution for client sign-off and developer handoff
- Iterate on designs based on usability testing and stakeholder feedback throughout the engagement
- Ensure designs are responsive across devices and screen sizes
- Clearly annotate UX flows and journeys in designs so developers understand interaction patterns, spacing, and component behaviour

Design System & Consistency
- Build and maintain a reusable design system and component library that keeps the UI consistent across the engagement
- Ensure all design work aligns to the client's brand standards and Teifi's design principles
Client Design Review & Sign-Off
- Run design reviews with the client, presenting design decisions clearly and incorporating feedback iteratively
- Support usability testing with end users where applicable, incorporating findings into design iterations
- Secure formal client sign-off on designs before build begins to prevent mid-sprint design changes
Accessibility
- Ensure all designs meet accessibility standards so the solution is usable by all end users
- Apply WCAG guidelines throughout the design process, not as an afterthought
Qualifications
- 4+ years of professional experience designing interfaces across web and mobile
- Proven ability to lead design on multiple projects simultaneously
- Strong portfolio showcasing UX and UI design work across complex digital products
- Deep understanding of UX principles, interaction design, and visual design fundamentals
- Experience producing wireframes, user flows, high-fidelity mockups, and design systems
