Jayajāta Kirk

Product designer, London

I design clear, trustworthy experiences for complex products, and help the teams behind them move in the same direction.

I’ve spent 15+ years designing digital products, the last eight at the John Lewis Partnership. At John Lewis I worked across the website and app – loyalty, navigation, checkout, account management and gifting – leading work through multi-team programmes in regulated areas.

Today I lead design at John Lewis Money across Travel Money, the Partnership credit card, insurance and loans, managing a small design team. I care about clarity, good thinking and evidence: working closely with product, engineering, content, legal and partners to turn messy problems into simple journeys, then testing and refining them.
