Mixpanel is hiring a Software Engineer to join the AI Platform team, a newly formed group at the center of Mixpanel's AI-first analytics vision.

About Mixpanel

Mixpanel’s AI-first digital analytics help teams accelerate adoption, improve retention, and ship with confidence. Its platform combines product and web analytics, session replay, experimentation, feature flags, and metric trees to deliver insights customers trust.

About the Team

The AI Platform team is a newly formed team at the center of Mixpanel's AI-first analytics vision. With a greenfield charter, the team is building infrastructure that accelerates and transforms AI product development at Mixpanel, both internally and for customers.

They provide tools to improve AI products, enabling internal teams and customer agents to build things that were previously unimaginable. The team builds shared infrastructure that is essential for developing AI features with confidence and speed, and that gives every agent the tools, context, and quality guarantees to act autonomously on behalf of users.

Some examples of what the team is building:

• Agent Optimization Framework: A system that optimizes AI products for quality, speed, and cost, using metrics from production and evals, given the context of the invocation.
• AI Agent Integrations and Accessibility: Products and tools that bring the power of Mixpanel to wherever it is most effective for customers, including a Mixpanel slackbot, MCP, and a public skills library.
• AI Engine: Services that centralize core AI and LLM functionality at Mixpanel in order to accelerate AI development, compound the value of AI efforts, and provide customers with a consistent experience.
