Senior Software Development Engineer, ZHL Operating System

About the team: Finding your dream home is only the first step — financing it is where the real complexity lives. On the ZHL Nexus team, we're building the Operating System (OS): the first-party platform where Zillow Home Loans operators run their entire day. Loan officers, processors, and support staff work hundreds of borrowers through origination, and today they do it across multiple tools and surfaces. We're replacing that with a purpose-built, operator-first experience — and we're doing it while the business runs at full speed. It's a fast-moving team with a direct line between the code you ship and the people using it. About the role: As a Senior Software Engineer on ZHL OS, you'll own significant surface area of the operator experience end to end. This role leans front-end: you'll shape our micro-frontend architecture, our shared component patterns, and the data-fetching layer that ties dozens of independently-deployed experiences into something that feels like one product.
