Senior Product Designer - B2B SaaS

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.
