• 4+ years of relevant work experience in frontend development, ideally within an institutional investment environment.
• Strong JavaScript/HTML/CSS foundation, with proven experience using modern frameworks (preferably React) to build sophisticated user interfaces.
• Deep understanding of UI/UX considerations for financial and modelling applications; prior experience developing bespoke frontends for quantitative applications is a strong plus.
• Experience designing and consuming REST APIs, with hands-on exposure to FastAPI, Flask, Express, or similar frameworks.
• Comfort handling structured and unstructured data across multiple formats, including JSON, spreadsheets, and flat files (CSV).
• Experience with Git/GitHub and standard software development practices, including integration testing, end-to-end testing, and user acceptance testing.
