• A track record of owning and delivering large, and complex cross-team initiatives.
• Comfort operating in ambiguity and turning it into clear plans and working systems.
• A hands-on mindset — you lead by building, not just by guiding.
• Strong product intuition and a focus on delivering real customer value.
