ROLE SUMMARY:

FTSE Russell is evolving its operational ecosystem, transitioning from a complex current operating model built on multiple business-as-usual (BAU) systems toward a more unified, scalable target-state platform experience (Phoenix). We are seeking a UX Designer who can bring clarity, coherence, and consistency across this landscape—designing experiences that meet today's needs while shaping the future!

This role focuses on internal users performing specialised, multi-step workflows. Your focus will be creating seamless, efficient, end-to-end experiences across BAU tools and emerging future-state capabilities — ensuring we avoid siloed, single-screen designs in favour of system-wide usability.

WHAT YOU'LL BE DOING:

Lead the User Experience Across the Ecosystem

Develop end-to-end workflows that span BAU systems and emerging Phoenix capabilities. Ensure every new design supports the broader operational journey — not just a localised UI improvement.

Maintain a clear experience vision that guides teams as tools evolve and converge.

Shape the Future Experience While Supporting the Present

Balance the needs of today's operating model with long-term platform objectives.

Guide teams through ambiguity toward clear, actionable outcomes as processes, systems, and capabilities advance.

Identify where UX can reduce complexity and support operational efficiency.

Create System-Level, Scalable Design Solutions

Develop coherent interaction patterns, behaviours, and navigation structures that work across diverse tools.

Promote reusable, consistent design across teams and products — avoiding the trap of one screen per problem.

Contribute to and evolve a design system used across internal operational tools.

Collaborate Across Functions

Partner with product managers, engineers, and operations teams.

Provide clear, evidence-based design recommendations that align technical feasibility with user value.

Facilitate design walkthroughs, critiques, and decision-making sessions.

Communicate Insights and Direction Effectively

Use storytelling, diagrams, prototypes, and structured artefacts to align team members.

Translate user needs, constraints, and behavioural insights into actionable design requirements.

Advocate for UX principles and scalable design thinking across the organisation.

Leverage Modern Tooling and AI to Accelerate Delivery

Use Figma to build high-quality prototypes, workflows, and design-system assets.

Apply AI to accelerate design and product development — automating routine tasks like layout adjustments and component generation, and generating rapid concept variations to speed up discovery and iteration.

Enable natural-language input to draft initial UI concepts, helping product teams visualise ideas sooner and reducing dependency on manual wireframing.

Strengthen quality and consistency through AI-supported checks for accessibility issues, spacing inconsistencies, and deviations from design-system standards.

Establish practices that enable faster design-to-development handoff — including AI-generated design documentation and patterns to reduce ambiguity and improve build accuracy.

WHAT YOU'LL BRING:

You don't need to tick every box, but you'll thrive if your background includes designing complex internal or enterprise tools where workflows span multiple systems. You may have created or contributed to design systems, delivered UX that bridges current-state and next-generation platforms, or worked in operationally critical, data-heavy environments. You've likely partnered with cross-functional teams, simplified multi-step workflows while respecting business rules, and communicated clearly with both technical and non-technical team members. Figma is your primary design tool, and you've experimented with AI tools to accelerate the design and delivery lifecycle.

Core UX & Design Skills

Interaction design, UI design, and workflow orchestration across multi-system environments.

Information architecture for interconnected tools and data-heavy interfaces.

Ability to synthesise complexity into clarity.

Strong visual, structural, and communication design skills.

Proficiency in Figma (components, variants, auto-layout, prototyping, design systems).

Experience applying AI tools to accelerate design work — including rapid concept generation, layout exploration, and content population.

Ability to use AI to support quality and consistency — such as accessibility checks, spacing validation, and design-system compliance.

Understanding of how AI can reduce handoff friction — from generating design documentation to enabling natural-language UI drafting for faster collaborator alignment.

Understanding of how design systems align with engineering implementation.

Behaviours

You're a systems thinker who sees the whole user experience, not just the screen in front of you. You're energised by dynamic environments where tools and processes are actively evolving. You're collaborative, curious, pragmatic, and focused on outcomes — advocating for users while balancing business and technical constraints.

Why Join Us
