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. You’ll be expected to own meaningful product work, step in when things are unclear or blocked, and help ensure we’re building the right things—not just designing them well.

You’ll own and design complex product areas end-to-end, while also acting as a close partner to the Head of Design - helping drive decisions, unblock teams, and maintain momentum when needed. This is a hands-on role. You’ll be expected to do deep product work yourself, while also raising the bar across the team through critique, direction, and strong product thinking.

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

Design and ship complex, high-impact features from concept to production
Act as a hands-on IC while helping guide overall design quality
Partner with Product and Engineering to shape what we build—not just how it looks
Review and critique work, pushing for clarity, simplicity, and strong execution
Align stakeholders and drive decisions, especially in ambiguous or fast-moving situations
Work closely with engineers to ensure high-quality, pragmatic implementation
Contribute to and evolve the design system

What we are looking for:

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
Comfortable operating in fast-paced, ambiguous environments
High attention to detail and ability to produce clear, implementation-ready designs
