Arize AI

45d•$165,000 - $200,000

About The Position

Arize AI is the leading AI & Agent Engineering observability and evaluation platform, empowering AI engineers to ship high-performing, reliable agents and applications. From first prototype to production scale, Arize AX unifies build, test, and run in a single workspace—so teams can ship faster with confidence. We're a Series C company backed by top-tier investors, with over $135M in funding and a rapidly growing customer base of 150+ leading enterprises and Fortune 500 companies. Customers like Booking.com, Uber, Siemens, and PepsiCo leverage Arize to deliver AI that works. We're looking for a UX Design Engineer to own and perfect the end-to-end user experience. The ideal person for this role obsesses over the details and can deliver improvements to the product. Most engineering teams treat UX refinement as an afterthought squeezed between feature work. We have a dedicated role for it because we believe the difference between "works" and "delightful" is what separates good products from great ones. You'll have the space to really care about craft. We're a technical team building for technical users. Your job is to make the experience of using our product enjoyable!

You've worked on complex tools (dev tools, data tools, B2B SaaS) where UX really matters
You've made products noticeably better through refinement (show us!)
You’ve built or contributed to design systems and animation libraries.
You've used feedback collection tools and incorporated user feedback into designs
