About The Position

As our Senior UX/UI Engineer, you'll own the design, architecture, and ongoing development of TaxRise's client facing web application, the platform our clients rely on throughout their entire tax resolution journey. Reporting to our Chief Data Officer, you'll be the primary technical driver behind the application's front end, responsible for the decisions that shape how it's built, how it scales, and how it performs in production. You'll work hands-on across the full product lifecycle, from wireframes and prototypes in Figma to production ready components built in React and TypeScript. You'll partner closely with our data team to understand system constraints and data structures, and you'll have a direct voice in what gets built next, not just how it gets built. This is a senior, high ownership role for someone who thrives at the intersection of design and engineering and wants their decisions to directly shape how thousands of clients experience TaxRise. This role is based onsite in Irvine, CA.
