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.
