About Ofcom

As the UK’s communications regulator, we’re delivering vital work that helps keep the UK connected and shapes the future of how we’ll stay connected with each other.

Our work covers everything from phones and broadband, through to TV, radio, the postal service, and wireless devices. We’re also taking on the challenge of making the online world a safer place. And we need people of all backgrounds, skill sets, and experiences to help us achieve our goal of making communications work for everyone.

About the Team

Almost every part of our lives is now online: we use online spaces to learn, play, make connections, do business and keep in touch. Alongside the many benefits, users face real risks from harmful or illegal content - from fraud, hate speech, bullying and harassment, child sexual exploitation, and more. Ofcom is the new regulator for online safety in the UK and there has never been a better time to join us on our mission to create a safer life online.

Ofcom’s role will be to hold online services to account for the steps they take to protect their users from harmful content, in order to ensure a safer life online for UK internet users. These roles provide an opportunity to help create a safer online environment and leave a lasting legacy for future generations.

The Group consists of five teams – Policy Development, Supervision, Strategy Delivery, Tech Policy and Online Safety Tech. This role sits within the Online Safety Tech team.

About the team you’ll be part of

The Online Safety Technology team conducts research to build knowledge and understanding in subject areas fundamental to online safety. This includes, for example, AI and machine learning, digital identity, privacy enhancing technologies, decentralisation, user experience, gaming, network infrastructure, and digital forensics. The team provides technical expertise to policy, supervision and enforcement colleagues in the wider Online Safety Group, and others in Ofcom, during policy development processes and industry engagement activities.

• Manage and support projects focussed on:
• examining in detail aspects of the systems, platforms and standards which are of concern to Ofcom;
• creating an evidence base for the application of a technology or combination of initiatives to tackle particular challenges relating to online safety, including informing assessments against regulatory expectations;
• identifying and analysing new technologies that present significant opportunities in areas where existing regulation may be incomplete; and
