About the team + role The Robinhood Legend team builds and owns our advanced desktop trading platform, designed to meet the needs of active and sophisticated traders. The team works across real-time data infrastructure, advanced charting, options and futures trading tools, and highly customizable workspace experiences. Their mission is to deliver a professional-grade platform that combines the power of institutional trading tools with Robinhood's signature approachable design. As a Staff Web Engineer, performance is your mandate. You'll set the standard for what a web-based trading platform can be — going deep on JavaScript internals, browser rendering pipelines, and real-time data optimization to make Legend the fastest, most responsive platform of its kind. For active traders, milliseconds matter, and you'll own the work that ensures Legend never gets in their way. This is a performance-first role. You'll lead the initiatives that make Legend faster and more efficient, while also contributing to feature development across core trading surfaces where your performance expertise has the greatest impact. The work balances deep technical execution with meaningful cross-functional partnership. This role is based in our Menlo Park, CA or New York, NY office(s), with in-person attendance expected at least 3 days per week. At Robinhood, we believe in the power of in-person work to accelerate progress, spark innovation, and strengthen community. Our office experience is intentional, energizing, and designed to fully support high-performing teams.
