Data Scientist
London - Hybrid
Circa £40,000 - £48,000
Our client's Data Science team uses data and machine learning to proactively monitor online advertising.
In this role you will work with the ads captured by the their Active Ad Monitoring system. You will work with images, videos and especially the text of ads from social media, search and web display. You will collaborate with experts across a range of advertising sectors to understand their needs. You will work primarily in Python to perform analysis to extract insight about prevalence of potential issues and help inform priorities. You will also train machine learning models and use LLM-based tools to filter large volumes of ads to find those that are relevant, or that break the rules. You will take end-to-end ownership of projects and will directly see how your work protects people in the UK from harmful and misleading content.
Current projects within the team focus on diverse topics such as ensuring influencer marketing on social media follows advertising rules; monitoring the green claims companies make to consumers; and making sure ads for cosmetic surgery abroad are responsible. You will report directly to the Head of Data Science, working alongside other Data Scientists and Data Engineers. As part of a developing team, you will have the chance to help shape our approach and ultimately the way data-led insight and machine learning is used to regulate advertising.
They are seeking candidates who believe in our mission, and who have strong technical and communication skills. You must be able to work with complex datasets in Python, and have an understanding of statistical concepts and machine learning. You must be comfortable communicating complex ideas to non-technical people. They welcome applications from those that have prior experience as a Data Scientist, and those who are seeking their first role after a relevant qualification.
They operate a hybrid working model and office attendance is required 40% of your contracted hours.
