At IMC, our trading tools are the environment traders and researchers live in all day. As a Lead UX Designer, you will help define how users understand the market, explore data, and make decisions in real time. This role combines deep workflow design with thoughtful, high quality user experience.

IMC is making a significant reinvestment in its trading platform, rethinking core tools, workflows, and interaction patterns from the ground up. You will be on the ground floor of that effort, with real influence over how the platform evolves and how great UX shows up across the firm.

You will work closely with traders, quantitative researchers, and engineers to design interfaces that are fast, intuitive, and well crafted. The goal is tools that feel natural under pressure, support complex decision making, and are genuinely good to use day after day.

• Balance efficiency with usability and visual quality across critical workflows
• Lead the evolution of shared design systems and interaction patterns
• Advocate for user centered design and usability testing throughout the product lifecycle
• Partner with engineering to ensure designs are feasible, scalable, and well implemented
• Navigate conflicting feedback and propose thoughtful tradeoffs aligned with user and business goals
• Help define and drive a UX vision aligned with the platform’s future direction

Your Skills and Experience

• Experience designing systems that are the central focus of a user’s entire day to day
• A strong portfolio demonstrating both interaction design and visual craft
• Experience working with complex or technical products in fast paced environments
