Senior UX Researcher (AI Products)

We are hiring a Senior UX Researcher to lead discovery and validation across AI-driven products within our venture portfolio.

This role focuses on understanding how people interact with AI systems and ensuring our products solve real user problems in trustworthy and effective ways.

You will study how users interpret, trust, and rely on AI-powered experiences, helping product and engineering teams build systems that are intuitive, reliable, and aligned with real user needs.

This role is part of the product discovery and validation function, supporting product managers, designers, and engineers with evidence-driven insights.

You will define research standards, lead user studies, and ensure AI-powered features are grounded in real user behavior.

This is a senior-level role requiring independent ownership, strong research expertise, and close collaboration with cross-functional teams.
