About The Position

MarketAxess is seeking a Senior UX/UI Designer to join their UX Design Team. This role is crucial for the multi-year transformation of their desktop trading platform, focusing on customer experience to ensure products are adopted and understood. The ideal candidate will have expertise in designing trading platforms and a deep understanding of financial markets. They will work closely with Product and Engineering teams during active build phases, contribute to future workflows, and translate complex processes into clear, high-quality solutions. The role involves designing dense, data-rich environments, including complex data grids and real-time trading workflows, often with a dark theme. A key aspect of this role is the integration of AI into the design process to accelerate quality and speed, from concept generation to prototyping and iteration. The designer will approach work through a customer experience lens, considering end-to-end workflows, user goals, and cross-application journeys, ensuring solutions are grounded in real user needs and fit seamlessly into the desktop ecosystem. Collaboration is key, working hand-in-hand with product, engineering, and QA to ensure UX intent is maintained from concept to release. The role also involves championing a user-centered, feedback-driven process, engaging directly with end-users, and advancing the company's design system for consistency across multiple themes and products. Ensuring workflows are ready for build, supporting go-to-market strategies, and advancing UX maturity within the organization are also core responsibilities.
