Staff Product Engineer - AI Platform

In this role as a Lead Product Engineer, you will work on a backend-leaning full stack team building customer-facing product features.

This role is a backend-leaning full stack position. The team is looking for engineers with strong Python backend experience who have worked on customer-facing product systems. While the role involves both backend and frontend development, the primary focus is building scalable backend services and APIs that power product features.

Candidates should have strong experience building backend systems using Python frameworks such as FastAPI, Flask, or Django, and be comfortable designing APIs and services that operate at scale.

On the frontend side, the team works with modern frameworks including React, Next.js, and TypeScript, so candidates should be comfortable contributing across the stack and connecting frontend interfaces to backend services.

The ideal candidate has a product mindset, enjoys shipping features end-to-end, and works closely with product managers, designers, and engineering teams to deliver high-quality user experiences. While the role is full stack, deep backend expertise in Python is the priority, with the ability to contribute to frontend development when needed.
