Senior UX/UI Designer

The Role

We are seeking a Senior UX/UI Designer to join our UX Platform Team with expertise in designing trading platforms and a deep understanding of financial markets. The ideal candidate is someone who has an acute sense for detail and can quickly translate complex workflows into intuitive, high-quality experiences, working closely with product and technology teams in a highly collaborative and fast-paced environment.  

You should be passionate about solving UX challenges, leveraging industry best practices and a user centered approach. You enjoy designing for large data, minimal whitespace and dark themes. You will be designing complex data grids, trade workflows and data visualizations in an innovative way that help create seamless user experiences.  

We embrace a culture of collaboration and experimentation while striving and encouraging all team members to focus on continuous improvement and learning. We openly welcome diverse perspectives and people who are not afraid to challenge assumptions and prior ways of working.  Otherwise, how do we innovate, learn and grow as a team and individuals? 

How You’ll Help Take Us There

• Build tools that match how users think and work: Through close collaboration with clients and internal stakeholders, you’ll ensure our products align with how traders think and work; ensuring each workflow aligns with user intent, reducing friction, clarifying next steps, and delivering intuitive, scalable, workflow-driven experiences that support real-world usage patterns.
• Design elegant solutions for complexity at scale: You’ll create high-fidelity designs/prototypes in Figma to communicate polished, production-ready concepts for our fixed income trading platform, crafting intuitive experiences across dense, data-rich interfaces that help users confidently navigate complex workflows in a fast-paced, high-stakes environment.
• Mentor members of design team: You’ll actively coach, support, and challenge designers across the team, helping them elevate their craft, solve complex problems, and grow in their roles.
• Collaborate to ship great products: You’ll work hand-in-hand with product, engineering, and QA to translate complex business and user needs into scalable design solutions, ensuring smooth implementation from concept to release.
• Champion a user-centered, feedback-driven design process: You’ll engage directly with end users to validate design decisions, uncover usability issues, and ensure our solutions are grounded in real-world insight, conducting research, synthesizing findings, and iterating on designs to deliver truly usable, client-centered experiences.
• Advance our design system: You’ll help evolve and govern our internal multi-theme design system in Figma, ensuring reusable patterns, visual consistency, and developer-ready handoff for both dark and light modes.
• Lead design reviews and enforce UX quality: You’ll set high standards for design excellence and consistency by leading critiques, providing thoughtful feedback, and ensuring our products meet the bar for usability, accessibility, and polish.
• Advance UX maturity across the organization: You’ll help refine internal processes, facilitate workshops, contribute to documentation, and advocate for UX, raising the bar for design across the organization. 

What We’re Looking For

• 7+ years of UX design experience in enterprise software environments
• 3+ years designing fixed income or trading applications

• Expert-level proficiency in Figma for prototyping and design system contribution
• Experience designing with complex data grids and dense UI components
• Strong ability to define workflows, gather cross-functional requirements, and communicate design decisions effectively

For job positions in NYC, NY, and other locations where required, the estimated salary range for a new hire into this position is £100000 GBP to £130000 GBP.

Collaboration and innovation are integral to our success – it's how we got to where we are and how we’ll maintain and grow our competitive advantage.
