The Role

We’re looking for a Lead UX/UI Designer to shape world-class user experiences across multiple delivery channels. This senior individual contributor role owns complex, cross-functional design initiatives and sets the bar for visual craft, interaction design, and evidence-based decision-making. You will own the CX roadmap based on customer feedback distilled by user research. You’ll partner closely with product managers, engineers, data teams and stakeholders across the business, helping drive both immediate improvements and long-term strategic UX evolution.

What You’ll Do

  • Design Leadership & Strategy
    • Lead end-to-end design for complex product initiatives—from discovery to delivery—spanning multiple channels and customer segments.
    • Translate ambiguous problem spaces into clear hypotheses, design directions and high-impact solutions.
    • Champion evidence-based design, shaping research questions, success metrics, and measurement plans.
  • Design Delivery
    • Produce user flows, information architecture, wireframes, high-fidelity UI and interactive prototypes using Figma at an expert level.
    • Facilitate complex stakeholder alignment with clear rationale, storytelling, and structured communication (workshops, Looms, walkthroughs).
    • Ensure your work meets the highest standards of craft, accessibility, and usability.
  • Mentorship & Team Support
    • Provide informal leadership, direction and feedback to junior/mid designers—uplifting quality, consistency, and design maturity.
    • Conduct design critiques, share best practices, and coach others on systems thinking and UX fundamentals.
  • Data-Driven Design
    • Partner with PMs, engineers and data analysts to define success events and measurable UX outcomes.
    • Use analytics tools (Heap or similar) to validate assumptions and inform iteration.
  • Design System & UI Standards
    • Extend and refine our design system with scalable, accessible components, tokens and patterns.
    • Create documentation that ensures clarity and consistency across teams.
    • Identify opportunities for convergence across products to improve coherence and efficiency.
  • Research & Customer Insight
    • Partner with researchers or independently run lean testing, including usability studies, concept validation, and rapid experiments.
    • Translate insights into actionable design decisions and iterate based on feedback.
  • Collaboration & Quality
    • Work closely with engineering throughout the build process, providing support, spec clarity, and QA collaboration to maintain design integrity.
    • Maintain organised, well-structured Figma files with clear naming, notes and versioning hygiene.

Qualifications

Knowledge, Experience And Skills

We are looking for an individual who is highly motivated, driven, and has a passion to be part of a fast-paced, successful team. Being a strong team player is also important as well as someone who is happy to work flexibly.

What You’ll Need

  • Demonstrated ability to lead design work independently and influence product direction.
  • Expert-level Figma capability: components, variants, tokens, auto-layout, prototyping, and design systems.
  • Strong interaction design skills and impeccable visual design craft.
  • Experience designing for multi-device experiences and responsive layouts.
  • Familiarity with analytics, experimentation, and metrics-driven iteration.
  • Superb communication, facilitation, and stakeholder-management skills.

  • Pragmatic, outcome-focused, and comfortable navigating large or ambiguous problem spaces.

Nice to have

  • Experience with dashboards, financial data, or information-heavy interfaces.
  • Experience in Agile environments (Jira, FigJam workshops).
  • Familiarity with accessibility standards (WCAG).

Success looks like

  • Clear improvements in user task completion, adoption, engagement or retention driven by your design work.
  • Strong alignment and clarity across product teams, with design strategy playing a key part in decision-making.
