Ideally showing how their execution had a direct correlation to impact and customer love * Deep, current knowledge of iOS platform standards and capabilities (Apple HIG, native frameworks), paired with the judgment to know when a bespoke, non-standard solution is worth building. * Experience creating tools, documentation, or training that help other designers and engineers level up their own craft, embodying a multiplier mindset over a "my feature" mindset. * Strong collaboration instincts. Demonstrating both proactive communications, working out in the open, and comfortable being pulled into ambiguous, cross-team problems rather than owning a dedicated backlog. * Familiarity with (or excitement about) agentic/AI-assisted coding tools, and interest in teaching design teams to use them to prototype directly in production codebases. * Excellent communication skills and the ability to evangelize new practices and get adoption across a design org, not just ship personal work.
