Senior UX Designer

About the Role 

MarketAxess is undertaking a multi-year transformation of our desktop trading platform, as part of this transformation, customer experience plays a critical role in ensuring our products ship with clarity, coherence and adoption readiness; not just polished screens. 

We are seeking a Senior UX/UI Designer to join our UX Design Team, with expertise in designing trading platforms and a deep understanding of financial markets. The ideal candidate is comfortable working alongside Product and Engineering during active build phases, while also contributing to the evolution of future workflows and broader platform experiences. You have a strong ability to quickly translate complex workflows into clear, high-quality, buildable solutions, while identifying opportunities to improve and scale the experience over time. 

You should be passioate about solving UX challenges, leveraging industry best practices, and a user-centered approach. You enjoy designing dense, data-rich environments, including complex data grids and real-time trading workflows, with minimal whitespace and dark theme. You will be designing complex data grids, trade workflows, and data visualizations in an innovative way that helps create seamless user experiences.  

This role is embedded within Product and Engineering teams and is responsible for innovating and defining the customer experience, ensuring UX readiness ahead of development, reducing ambiguity for engineers, and maintaining end-to-end workflow integrity as features move from discovery through launch. This is a hands-on, delivery-oriented role operating in a fast-moving, AI driven, highly collaborative environment.  

How You’ll Help Take Us There 

• Build workflows 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.
• Use of AI in the Design Process: The design process should incorporate AI where it can accelerate quality and speed, including early concept generation, exploration of workflow options, synthesis of feedback, prototyping and iteration on design directions. AI should be used as an enabler within the design process to help the team move faster, evaluate more possibilities, and focus effort on higher-value strategic decisions. 
• Customer Experience, Research & Discovery Approach: Approach this work through a customer experience lens, considering end-to-end workflows, user goals, cross-application journeys, and adoption readiness, not just the interface. A focused discovery phase should validate assumptions and uncover user behaviors and pain points through feedback, usage signals, and iterative testing. This ensures the solution is grounded in real needs, fits naturally into the desktop ecosystem, and can move efficiently into build to deliver near-term value. 
• Apply a customer experience approach supported by AI: You’ll leverage AI to accelerate concept generation, exploration, and iteration, while designing with a holistic customer experience lens—considering end-to-end workflows, cross-application journeys, and alignment to broader desktop strategy. 
• Unified Desktop Strategy: Contribute to a more connected, intuitive, and scalable experience across applications. This includes alignment to shared workflows, platform consistency, and longer-term opportunities to improve the overall customer experience across the trade lifecycle. 
• 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 UX intent is clearly defined, understood and maintained 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 set high standards for design excellence and consistency by evolving our internal multi-theme design system in Figma, ensuring reusable patterns, visual consistency, and developer-ready handoff for both dark and light modes.
• Ensure workflows are ready for build: You’ll define workflows, states, transitions, and edge cases before work enters development, helping teams move faster with fewer mid-sprint clarifications and less rework.
• Support go‑to‑market and adoption readiness: Contribute to workflow-based demos, help teams explain the experience clearly to clients, and support launch readiness by identifying adoption risks and ensuring solutions align with real-world usage.
• Advance UX maturity & evolve workflows: Drive UX maturity across the organization by refining processes, facilitating workshops, contributing to documentation, and advocating for design. At the same time, identify patterns, gaps, and opportunities to continuously improve workflows—helping to create a more consistent, scalable, and intuitive user experience over time. 

What We’re Looking For 

• 7+ years of UX design in enterprise software environments
• 3+ years designing fixed income or trading applications
• Experience with desktop applications and desktop interoperability frameworks (e.g., OpenFin, Interop.io, Electron, FDC3)
• Expert-level proficiency in Figma for prototyping and design system contribution
• Ability to leverage generative AI tools to accelerate wireframe creation, explore design variations, and validate concepts through rapid prototyping
• Proficiency in utilizing AI for user research to uncover behavioral patterns, predict user needs, and identify friction points; informing evidence-based design decisions
• Experience applying AI-driven accessibility and quality checks to audit and validate UI designs against established standards, ensuring inclusive and compliant user experiences
• Strong understanding of prompting AI to generate and maintain design documentation, specifications, and component guidelines to ensure consistency, accuracy, and scalability across the design system 
• Designing with complex data grids and dense UI components
• Familiarity with multi-theme, scalable design systems across multiple products
• Excellent communication, facilitation, and stakeholder engagement skills
• Comfortable operating in fast-paced, ambiguous environments with high complexity
• Strong ability to define workflows, gather cross-functional requirements, and communicate design decisions effectively
