About the role
We’re looking for a Senior Product Designer who operates with a high degree of ownership and judgment. This is a high-trust role.

This role will be in-office 4 days a week.

6+ years of product design experience
Strong track record of shipping complex B2B products
Experience guiding or mentoring other designers’ work
Ability to make strong product and design decisions with incomplete information
