Do you enjoy solving complex engineering challenges, experimenting with new approaches, and working in an environment that combines the discipline of an enterprise platform with the curiosity and pace of a startup? At BlackRock, we look for engineers who are excited to push the boundaries of modern frontend development - from advanced UI frameworks to high‑performance micro‑frontends and platform‑level tooling that sits at the heart of investment workflows handling real financial outcomes. In Core UI Engineering, you’ll work on systems that operate at global scale and evolve the foundations of our web platform. This includes building reliable, performant user experiences, shaping shared frameworks, and increasingly exploring how AI‑assisted workflows can accelerate how we design, code, and deliver value. We are evolving toward purpose driven, outcome oriented product engineering, where humans guide and validate AI generated output while taking full responsibility for product, engineering, and business outcomes. Our technology supports Portfolio Management teams overseeing over $14 trillion in assets, and the products you build will sit at the heart of tools used daily by investors making decisions that impact millions of people worldwide. It’s engineering work with real reach, real complexity, and real impact.
