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.The Opportunity We’re looking for a Senior Frontend Engineer who cares deeply about how fast, stable, and intuitive complex AI systems feel in the browser. You’ll spend the vast majority of your time in React + TypeScript, owning frontend architecture, performance, and instrumentation.  Our customers are high performing teams running agents and models in production. Your job is to make those workflows feel instant, predictable, and trustworthy. What You’ll Do Spend most of your time building rich, performant frontend experiences in React + TypeScript (dashboards, traces, configuration flows, real-time views). Collaborate with backend engineers on requirements, define API contracts, implement UI, and ship with metrics, logs, and alerts wired up. Design and implement patterns built for scale that work under real data and load. Lead frontend architecture decisions around routing, data fetching, caching, and client-side error handling. Use analytics tools, browser performance profilers, and Core Web Vitals to measure, debug, and continuously improve frontend performance. Build and iterate on visualizations for model performance, agent behavior, and real-time signals by paying attention to rendering performance and perceived latency. Drive UI resilience: robust loading states, optimistic updates where appropriate, pagination / virtualization, retry logic, and graceful degradation. Provide technical leadership: reviewing designs and PRs, mentoring engineers on frontend patterns and performance, and raising the bar on UX quality in code. You're a great fit if: You have 5+ years of experience building user-facing web applications, including senior-level ownership of complex, high-impact projects. You’re fluent in React and TypeScript, and have helped shape or modernize a frontend stack. You have practical experience with GraphQL (schemas, queries, mutations, performance considerations) and at least one GraphQL client. You’ve worked on performance-sensitive or data-heavy products (dashboards, observability, dev tools, ML platforms, real-time UIs). You use metrics and traces to guide performance work. You care about UX quality such as loading states, error states, keyboard shortcuts, micro-interaction, and express that care through clean abstractions and solid architecture. You’re energized by education Bonus Points, But Not Required Experience with data visualization libraries (D3, Vega, Plotly, visx, Recharts, etc.) and awareness of their performance tradeoffs. Experience with Python or Go services, especially in distributed or high-throughput environments. Experience setting up fine-grained product analytics and performance dashboards to track user journeys and frontend SLIs/SLOs. The estimated annual salary for this role is between $175,000 - $200,000, plus a competitive equity package. Actual compensation is determined based on a variety of job-related factors that may include transferable work experience, skill sets, and qualifications. Total compensation also includes a comprehensive benefits package, including medical, dental, vision, a 401(k) plan, unlimited paid time off, a generous parental leave plan, and additional support for mental health and wellness.
