Senior Product Designer (B2B SaaS)

About the role

What you'll own

• End-to-end design for complex, ambiguous problems on a product surface. From problem framing through customer research to final shipped UI. You drive your own discovery; you do not wait for briefs.
• Customer research. Run interviews independently, synthesise findings, convert to design direction. You speak to internal customers - not always through PM.
• Design system contributions. Extend primitives, propose new patterns, document conventions. Your contributions outlive your tenure on any single feature.
• Mentoring designers. Code review the design equivalent: review work, give critique, unblock craft questions. Engineers and PMs see you as a craft mentor across the team.
• Driving design critique sessions. Structure feedback rounds, raise the bar across the team.
• Written design rationale. You produce design decision documents, principles, and decision logs as a default - not when forced.
• Cross-functional partnership. Surface design constraints early to PM and engineering. Bring reasoned alternatives. Operate as a peer, not a delegate.
• Pixel-level craft and accessibility on your own work and surface.

Must-haves

• 4-7 years of professional product design experience
• B2B enterprise SaaS experience: substantive senior-level work on dense, professional UI for business users at scale (permission models, complex tables, audit-grade interaction patterns, multi-tenant data, regulated workflows)
• Track record of independently designing complex, ambiguous problems from research through ship at a previous role
• Demonstrable design system contributions (extended primitives, proposed patterns, documented conventions)
• Articulate written rationale for design decisions; you can show us a document you authored
• You have mentored at least one junior designer in a past role and can name what changed
• Comfortable challenging PMs, engineers, and founders with reasoned design alternatives
