Gemma Trebble

My first job, at aged 19, was as an office junior at a small tech start-up. Bored of making tea and being the dogsbody, I would sit with the designers and developers and ask endless questions, wanting to know exactly how they crafted dynamic, sophisticated software. Fast forward 4 years, I’d successfully graduated with a degree in Interactive Multimedia and was back managing digital projects with a junior trainee of my own.

As a Senior digital designer at the BBC, I led the radical redesign of the homepage and core sport indexes; creating a flexible UX framework that served rapid, live editorial and an enthusiastic, highly opinionated fan base of millions. I initiated A/B and multi-variant testing to make data-led design decisions that accurately responded to user behaviour. I led the responsive digital design strategy for the ‘Summer of Sport’; the BBC’s coverage of 2014’s big sporting events including FIFA World Cup, Wimbledon and the Commonwealth Games across mobile, tablet, desktop and IPTV. This brought together live digital broadcasts, online editorial and pundit commentary alongside real-time data for multiple sports simultaneously.

I joined Barclays in 2015 as Lead UX Designer for the Mobile Banking app. Being based at the Technology Centre offered me the opportunity to bring experience design, development and test closer together. During my first year, I brought solution architects in to shape propositions earlier, challenged briefs and helped to plan hack days that drove innovation. I delivered numerous live features which directly contributed to a steady increase in NPS of the banking app, which now has 6 million active users. Following my promotion to Design Principal, I now lead a team focusing on digital initiatives for Wealth and Premier as well as leading projects helping community and vulnerable customers understand how to manage their money better.
