Product / UI Designer
Department: Marketing
Employment Type: Fixed Term - Full Time
Location: London
Reporting To: Head of Marketing & Planning

Description
Shape a best-in-class design system that powers both product and digital experience across a multi-brand platform.

Turn complexity from multiple acquisitions into one seamless, scalable user experience.

Role Overview:

We’re at a pivotal stage of transformation, following multiple acquisitions across the adviser technology and insights space. Now, we’re consolidating these into a unified, future-ready experience — rethinking how our platforms, products and digital experiences come together.

This role will play a critical part across two major initiatives:

Creating a unified digital experience through a new CMS and website ecosystem

Designing the product experience for Defaqto Unity, our consolidated adviser platform

In summary, an exciting opportunity to define a design system that scales across brands, audiences and products — and is built for the future, including AI-driven experiences

What you need to deliver

Establish a unified, scalable design system across Defaqto.com, Unity and sub-brand sites

Ensure a seamless experience across marketing and product environments

Define what remains consistent (components, layout, interaction) and what flexes (tone, imagery, emphasis)

Create a system that works across multiple brands and audiences

This will include:

Design tokens (colour, typography, spacing, layout, iconography, interaction)

A comprehensive component library (navigation, forms, data display, CTAs, states)

Interaction patterns for key workflows and user states

Page templates and layout systems for both marketing and product use cases

Define components and patterns in a structured, explicit and unambiguous way

Document rules, constraints and usage clearly

Ensure outputs can be used by AI to generate and maintain pages without interpretation

End-to-end journeys from marketing site through to logged-in product experience

Adviser workflows (fact find → recommendation → submission → review)

Consumer journeys (discovery → understanding → action

One consistent experience across marketing and product

Data-first interfaces with a single source of truth

Clarity and usability over visual decoration

Consistency at scale across all touchpoints

Modular, component-based design (Atomic Design approach preferred)

A system that scales across multiple brands without redesign

A seamless experience across web and product

Outputs that are structured enough for AI-driven assembly

Clear, intuitive design that can be understood quickly and applied consistently

What you'll need to succeed:
Relevant qualification in UX, UI, Product Design or similar (or equivalent experience)

Strong understanding of design systems and scalable UI architecture

Experience designing across both marketing websites and software products

Familiarity with multi-brand environments and complex digital ecosystems

Awareness of emerging AI design considerations is advantageous

Expertise in UI design, interaction design and component-based thinking

Ability to translate complexity into clear, usable design patterns

Strong documentation skills — structured, precise and scalable outputs

Collaborative approach with the ability to work across product, marketing and tech

Proven experience designing and delivering design systems at scale

Experience working across complex, multi-product or post-acquisition environments

Background in B2B, SaaS or platform-based products is highly desirable

Experience contributing to or leading large-scale digital transformation projects

Comfortable working at pace in a short-term, impact-driven contract

Able to operate independently while aligning with a wider vision

Highly structured, detail-oriented and pragmatic

Focused on delivering solutions that scale, not one-off designs

Important to know:

Location:
This role can be worked on a UK remote or hybrid basis. Ideally, we'd like you to be able to work onsite in our London office from time-to-time for collaboration purposes and to get to know key stakeholders face-to-face but this isn't essential.

Right to Work:

Applicants must already hold a legal right to work in the UK without time restrictions and without the need for future sponsorship. We are unable to provide Skilled Worker visa sponsorship.
