Company mission
To make the world’s AI work and work for the people.
Role
Who you are
- You've made products noticeably better through interaction refinement (show us!)
- You're comfortable with modern frontend frameworks and animation libraries
- You've used session replay tools and incorporated user feedback into designs
- You can work in Figma to prototype before committing to code
- You think about edge cases, loading states, and empty states automatically
- You've worked on complex tools (dev tools, data tools, B2B SaaS) where UX really matters
- Bonus: You've built or contributed to design systems
What the job involves
- AI is rapidly transforming the world. As generative AI reshapes industries, teams need powerful ways to monitor, troubleshoot, and optimize their AI systems
- That’s where we come in. 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
- Most engineering teams treat UX refinement as an afterthought squeezed between feature work
- We're carving out 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 (ML engineers, researchers) who are drowning in complexity
- Your job is to make that complexity manageable and maybe even enjoyable
- We're looking for an engineer who obsesses over the details that make complex tools feel effortless
- You'll work on our LLM evaluation and prompt experimentation platform, taking functional features and refining them into intuitive, polished experiences
- Refine and iterate on UX for existing features - you won't build from scratch, but you'll make things significantly better
- Watch real users struggle in Fullstory, identify friction points, and fix them
- Prototype interaction alternatives rapidly (in Figma or code) to test different approaches
- Work closely with our Senior engineers who own feature architecture - they build the foundation, you perfect the interface
- Own the "feel" of the product: transitions, feedback, error handling, progressive disclosure
- Build reusable interaction patterns that the team can leverage
- Run lightweight usability tests to validate improvements
- A typical week might include:
- Watching 10 user sessions, identifying 3 common friction points
- Prototyping 2 different flows for evaluator configuration in Figma
- Implementing the winner with smooth transitions and helpful inline guidance
- Pairing with Staff engineers to refactor a complex form into a multi-step wizard
- Running a quick usability test with 5 users on the new onboarding flow
Our take
Machine learning is rapidly becoming a fundamental and mainstream automation tool used across many industries. The issue, however, is that monitoring, assessing, and improving ML models is costly, and especially tricky without monitoring capabilities. It’s created a market demand for ML monitoring tools, and Arize’s platform offers a rich suite of them.
The Arize platform gives developers and operators comprehensive oversight of their models with tools including performance tracing, drift detection, and integration and deployment. This provides a crucial guardrail: as more decision-making is handed over to ML in areas like insurance and loans, poor ML model performance can have a catastrophic effect on both individuals and customers alike.
Remarkably, given this development, ML observability platforms aren’t yet in huge supply. Arize startup rivals like Censius and WhyLabs are making strong headway, but a clear winner has by no means yet emerged. Arize has, however, netted some major customers: Spotify, Instacart, Uber, and P&G are a handful of the major clients that will help it lay a strong foundation in what is anticipated to be a highly lucrative market.

Company values
- Do > Say - We believe in building, not just talking. Execution matters more than meetings, and progress beats process. Instead of endless debate, we prototype. Instead of bureaucracy, we ship. AI moves fast—so do we.
- N+1 - Good enough isn’t good enough. We believe in continuous improvement—whether it’s improving AI-powered systems, our product, or ourselves, there’s always a better version to build, iterate, and level up.
- Bring Solutions - Spot a problem? Own it. We don’t waste time on complaints or excuses—we focus on fixing, improving, and building. Whether it’s a blocker in a project or a gap in how we work, the expectation is simple: push for a better way forward.
