The Opportunity

Our client, a global leader in financial intelligence, is looking for a Senior UI Designer to join their team on a contract basis. This is an exciting chance to be part of a business that is rethinking the way professional tools are designed and used.

You'll play a key role in building a new design system and visual language from the ground up, directly shaping tools relied upon by investors and fund managers around the world.

What's In It for You?

• A chance to own and influence design systems at enterprise scale
• Hybrid flexibility - only one day per week in the London office
• The opportunity to showcase your portfolio and make a tangible impact on real-world products
• Work with a talented team where design, engineering, and product work hand in hand

The Role

As Senior UI Designer, you'll:

• Build and evolve a scalable design system with strong knowledge of design tokens
• Create well-structured, Figma files that are handover-ready for engineering
• Develop high-fidelity prototypes to support user testing and stakeholder buy-in
• Apply technical awareness when designing for frameworks such as JavaScript, Tailwind CSS, and Bootstrap
• Present a portfolio that demonstrates functional, scalable, and visually compelling interfaces

About You

We're looking for someone who combines creativity with technical know-how. You'll have a proven track record of delivering polished, functional user interfaces that align with brand identity while enhancing usability.

This role is perfect for a designer who wants to move beyond execution and take ownership of building a design culture within a forward-thinking business.
