Tom Clark

Head of Common Platform


Tom's spent 16 years working with technology across a number of sectors, from manufacturing with Jaguar Cars to media with the BBC, Global Radio and most recently ITV. During this time he's held senior and lead positions in several disciplines, including engineering, development and architecture.

As Head of Common Platform at ITV, he's responsible for developing the common hosting platform that underpins all of their key applications. He'll always be an engineer at heart, but now his day job is managing and developing the diverse team of "smart and kind" people that build, maintain and advance the platform.


Tom Padgham

Head of Operations


Tom is currently leading the Infrastructure community on the largest agile project in the Department for Work and Pensions (DWP), instilling DevOps best practices across the different technical communities, and setting an example for projects in the wider department to follow. DWP are undergoing an extensive digital transformation in an organisation of 98,000 people which brings with it huge challenges embedding DevOps across a large and diverse organisation that has outsourced IT for the past 20 years.

Tom has a broad range of experience in his IT career, making him well placed to understand the value of DevOps. Having started out as a Java developer, developing deployment tooling within only a few weeks, and moving through various roles in disciplines such as configuration, release management, and service support, he now leads Infrastructure specialists, giving him an appreciation of all facets of DevOps to ensure success."
