The ASA is the UK s regulator of advertising across all media, including online. Our work includes taking proactive action against misleading, harmful, offensive or otherwise irresponsible ads and acting on complaints. In short, we make sure ads are legal, decent, honest and truthful.

In this role you will join our Data Science team and work on our world-leading Active Ad Monitoring system, which uses AI to proactively monitor online advertising. In 2025 the system captured and processed 60 million ads across social media, search and programmatic display. The ASA uses this intelligence to help regulate ads across high-priority topics like injectable weight-loss medications, green claims companies make to consumers, disclosure of influencer marketing and many more.

You will be analysing the large volumes of ads the Active Ad Monitoring system captures, providing intelligence that helps teams across the ASA tackle real-world issues in online advertising. You will work primarily in Python, making extensive use of AI models to extract meaning from text, images and videos, and turning unstructured data into actionable intelligence. You will also have a role in helping understand how AI can help accelerate processes across the ASA.

Our team mission is to protect UK consumers from adverts that are misleading, cause harm and target those within our society that are the most vulnerable. Working as part of our small agile team you will have the opportunity to own your work end-to-end, seeing directly how the work you do helps protect UK consumers.

About you

You will have a genuine enthusiasm for using Data Science and AI to improve ad regulation in the UK

You will have either previously been a Data Scientist, or have similar professional experience, for example in data-intensive academic research or as an analyst with Python experience

You will have the ability to write high-quality Python code to manipulate complex datasets

You will be able to communicate clearly with non-technical coworkers, understanding the challenges they face regulating online advertising, and coming up with ways to use the technical tools at your disposal to help solve them

You will have experience with Large Language Models (LLMs) either professionally or through personal exploration

You ll be impact focused- understanding the problems the ASA faces and prioritising technical solutions that will deliver real impact.

You will need to be curious and ambitious, creatively solving problems that may arise whilst always having an eye on system/process improvements.

The Company

We are the UK s independent frontline regulator of ads by legitimate businesses and other organisations in all media, including online. We are authoritative and influential on ad regulation; the centre of expertise. The rules we administer and enforce are contained in the UK Advertising Codes, written by the industry Committees of Advertising Practice (CAP). To help maintain our independence from the industry that funds us, we are primarily funded at arm s length by the Advertising Standards Boards of Finance (Asbof). Together, the ASA, CAP and Asbof make up the ASA system.

Our purpose is to make sure ads are responsible. Our ambition is to make sure every UK ad is a responsible ad. Our values are to be proactive, collaborative, accountable, transparent and decisive. We want external stakeholders to find us to be: independent in administering the Codes; evidence-based, proportionate, targeted and consistent; and reflective of society, not a social engineer.

We are passionate about what we do because responsible ads are good for people, good for society and good for business. They entertain and inform us, helping us to choose products and services. They fund the media, sport and culture we all enjoy. They can be a force for social good, encouraging us to contribute to good causes, make more responsible choices and stay safe. And they help deliver competition and power the economy. By making sure ads are responsible, we protect people from being misled, harmed or offended, helping them feel more confident in the ads they see and hear.
