OSS Design Engineer

The Opportunity

AI is rapidly transforming the world. Whether it’s developing the next generation of human-level intelligence, enhancing voice assistants, or enabling researchers to analyze genetic markers at scale, AI is increasingly integrated into various aspects of our daily lives.

Arize AI is the leading AI observability and evaluation platform, empowering AI engineers to build and deploy high-performing, reliable models. As the AI landscape shifts from traditional ML to generative AI and agentic systems, Arize ensures teams have the tools to monitor, troubleshoot, and improve AI in production.

The Role

Join Arize AI to build ambitious interfaces, prototype new ideas, and push the boundaries of what’s possible in AI development, evaluation, and observability. You’ll design, refine, and ship experiences that help AI teams understand, troubleshoot, and improve the AI systems that power their next-gen applications!

What You’ll Work On

We’re a small team where everyone wears multiple hats, and you’ll have a chance to make a meaningful impact across a wide range of projects. You’ll:

• Design and build compelling product experiences for Arize Phoenix and Arize’s commercial platform.
• Create reusable components and templates for our design system, taking them from initial concept to shipped features in production.
• Prototype new AI features and UI patterns to explore innovative ways of visualizing AI performance, surfacing anomalies, and explaining AI behavior.
• Develop interactive demos and data visualizations to help users quickly grasp complex AI concepts, such as embeddings, agent workflows, etc.

Produce polished assets— illustrations, animations, videos, images— for the product, documentation, and beyond.

Upcoming projects you’d tackle after joining:

• Design and build a fresh set of components that are beautiful, accessible, and easy to use.
• Prototype novel data visualizations for complex AI interactions.
• Overhaul our documentation for clarity and accessibility, ensuring both new and advanced users find the help they need quickly.

Explore new color palettes and branding to continuously up-level the design for both accessibility and aesthetics.

What We’re Looking For

We’re looking for a Design Engineer with a strong UI engineering foundation, an obsession with good design, and a passion for making AI more understandable. You likely share our core values:

• You love to design—in code. You’ve built polished, production-ready interfaces and consider code your ultimate design tool.
• You’re fanatical about the details. You notice every pixel misalignment or unsmooth animation, and you’re willing to iterate until it’s just right.
• You dive deep. You’re curious about how underlying AI systems work and experiment constantly to push what’s possible in the browser.
• You embrace new technologies. Whether it’s the next CSS spec or a new JavaScript framework, you’re excited to explore and test it out.
• You’re a great teacher. You can break down complex design or technical topics into digestible, engaging content for the community.
• You’re good at scoping. You know how to slice big ideas into manageable chunks and ship incrementally.
• You’re a self-starter. You look for ways to improve user experiences without waiting to be asked.

On the technology side, you’ll thrive if you have expertise in:

• React (our main framework for everything from open-source demos to production apps).
• TypeScript (we rely on it to keep our codebase clean and maintainable).
• Semantic HTML & Accessibility (our users trust that we hold a high bar for quality and inclusivity).
• Charting libraries / WebGL (we leverage all means necessary to provide great data visualization).

UI/UX best practices (experience with data-heavy dashboards, experimentation tools, or ML workflows is a plus).

Why Work With Us

• We’re here to make AI work—and work for the people. We’re building the leading observability and evaluation platform for AI systems, already used by cutting-edge teams to analyze millions of predictions daily.
• We ship. We believe in quickly delivering real value so we can iterate, learn, and keep improving.
• Our work has impact. Arize powers mission-critical AI across multiple industries, and your designs will help shape how people build and monitor AI solutions globally.
• We’re small, on purpose. You’ll work side-by-side with the head of OSS and have a direct hand in setting our product vision, and get credit for your contributions.
• We’re fully remote. We collaborate across time zones using Slack, Zoom, Figma, and GitHub—but also have offices in the Bay Area and NYC for those who prefer an in-person vibe.
• We’re well-funded and independent. We’re not beholden to short-term investor demands, and we have the runway to take calculated risks and build the right way.
• We care about doing great work. We sweat the details, celebrate craftsmanship, and aim to create a product experience that delights our users.
• We’re not afraid to have fun. We keep a sense of humor and humility about ourselves, knowing that at the end of the day, we’re all here to build something genuinely helpful and meaningful.

How to Apply

To apply, write something specifically for this position that tells us why you’re a great fit for Arize AI. We want to see:

• Projects you’re proud of—especially ones you designed and coded yourself.
• What excites you about AI and where you see the biggest opportunities to improve the user experience around machine learning.
• Contributions to open source, whether you’ve launched your own project, made a valuable pull request, or written a stellar bug report.
• Teaching ability—show us any tutorials, blog posts, or talks you’ve created to help others learn complex topics.

Please include a link to your portfolio, GitHub, or any relevant examples of your design and engineering work. We can’t wait to see what you’ll bring to Arize AI!
