Jess Hall is Chief Product Officer at Just Eat Takeaway.com, one of the world's leading on-demand delivery platforms, connecting hundreds of thousands of partners with tens of millions of consumers across 17 international markets. She leads the global product vision powering this ecosystem, evolving the platform beyond food delivery into a broader digital high street for everyday convenience. With nearly two decades of experience building and scaling digital platforms used by millions of people every day, Jess has held senior leadership roles at some of the UK's largest consumer businesses, including Tesco, Argos and Sainsbury's, leading large-scale transformation in complex retail and technology environments. She has been at the forefront of applied AI in consumer platforms for years, most visibly when she led the deployment of the first autonomous wheel-legged delivery robots in Europe. But the work she is most proud of sits closer to home: she created JET's early careers programme from scratch, deliberately designed without degree requirements, hiring on potential rather than credentials. Three cohorts in, over 52% of each intake are women, 95% graduate into full-time roles, and the cohort includes career switchers from nursing, teaching, veterinary work, and documentary filmmaking. In a sector that has historically locked women out by insisting on CS or maths degrees, Jess used her platform to open a different door. A longstanding advocate for women in tech and business, she speaks regularly on the importance of active sponsorship and building genuinely diverse talent pipelines. Outside work, Jess is a mother of two, a tennis player, a runner, and a reader with an ambitious annual book target and no apologies for it.
