UI/UX Developer

About the Role Jump Trading is seeking a resourceful UI/UX Developer to build internal trading tools used by traders and operators in real time. This role blends product thinking with hands-on frontend engineering to accelerate decision making and improve workflow efficiency in a fast-paced trading environment.

What You'll Do

• Build high-performance, mission-critical UI applications for real-time trading workflows.
• Partner directly with traders, operators, and business stakeholders to understand pain points, define priorities, and shape the product roadmap.
• Deliver value in small, fast, feedback-driven iterations rather than large, slow releases.
• Take an entrepreneurial, ownership-driven approach: identify opportunities, prototype quickly, and drive solutions from idea to production.
• Design products with a platform mindset, creating pluggable workflows, reusable UX patterns, and extensible architectures.
• Balance short-term business needs with longer-term abstraction and reuse — knowing when to solve something specifically and when to generalize.
• Contribute across the stack when needed, including APIs and backend integrations.
• Debug and resolve production issues with urgency and strong root-cause analysis.
• Help improve architecture, performance, usability, and reliability across the trading tools suite.
• Other duties as assigned or needed.

What We're Looking For

• At least 4 years of front-end development experience with TypeScript, HTML, CSS, or similar technologies.
• At least 4 years of experience with React or similar frameworks, ideally for real-time, streaming, or data-heavy applications.
• Strong experience working directly with business stakeholders and turning ambiguous requirements into shipped solutions.
• Clear evidence of resourcefulness, ownership, and entrepreneurial problem-solving.
• Experience working in fast-moving, iterative environments such as fintech, startups, or agile product teams.
• Ability to think of a product as a platform; building modular, extensible systems with reusable workflows and UX.
• Comfort operating in ambiguity and chaos, while bringing structure, prioritization, and momentum.
• Exposure to backend development using Python, Golang, or similar languages.
• Strong software engineering fundamentals, including API design, testing, maintainability, and scalable architecture.
• Deep understanding of core CS and web concepts, with the judgment to choose the right tools for the job.
• Strong grasp of browser/runtime behavior, networking, data structures, performance tradeoffs, and real-time application design.
• Ability to build for low-latency, high-accuracy, mission-critical use cases, where off-the-shelf web libraries are not always enough.
• Excellent communication skills and the ability to work effectively across technical and non-technical teams.
• Bachelor's degree in Computer Science, Computer Engineering, or related field.
• Reliable and predictable availability.

Nice to Have

• Think like a builder, not just an implementer.
• Can move from a one-off workflow to a reusable platform capability.
• Know when to leverage a framework and when to build something lighter or more specialized.
• Care deeply about product outcomes, not just code delivery.
