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.

About Arize Phoenix

Large Language Models (LLMs) like GPT-4 are capable of human and super-human reasoning, but they don’t understand your personal data, are unable to perform complex tasks, remember the actions they performed yesterday, and so on. The core mission of the Arize OSS team is to enable developers to build LLM-powered applications with safety and observability in mind.

We are at the forefront of a new way to build software. Doing this successfully will usher in a new age of knowledge automation and completely redefine the modern tech stack.

Our product offerings consist of an open-source TypeScript library as well as an enterprise platform. Arize Phoenix has hundreds of thousands of monthly downloads and is used by large enterprises and early-stage startups. We’re backed by TCV, Foundation Capital, Swift Ventures, and Battery Ventures.

• Worked with product and design teams, and demonstrated initiative in scoping and designing features.
• Shipped applications that scaled to millions of users.
• [Bonus] Machine learning experience.

Values we look for:

• Integrity, Alignment, and Passion
• Adaptability and resourcefulness
• Intellectual horsepower (Smart x Get Things Done)
• Elevate those around you
• Domain-specific knowledge

• Rapidly learning new technologies
• Pushing outside your comfort zone
• Maintaining high code quality despite industry experience level
• Thinking critically about system and product design
