We have over 1000 Brainlabbers based across the global, all united through the 12 principles laid out in our Culture Code. We're full-service, with people and AI agents working side by side, all aligned to one thing: maximizing our clients' revenue through a genuinely scientific approach to media. If you want to help play your part in achieving this for the world's biggest brands in an environment that will support and challenge you in equal measure, this is where you do it. As the Manager, Data Science, you will support the delivery of Google Meridian MMM projects and other data science engagements for Brainlabs clients, working closely with the Director of Data Science to produce technically rigorous, clearly communicated outputs. You are responsible for the quality of your own modelling work and for helping clients understand what the analysis means for their media decisions. This is a role for a data scientist who is strong on the technical fundamentals, curious about how marketing data can drive better business decisions, and developing the skills to communicate complex ideas clearly. What you do Support MMM Project Delivery: You contribute to the delivery of Google Meridian and other MMM projects, owning specific workstreams including data preparation, model runs, and scenario analysis under the direction of the Director of Data Science. Deliver Other Modelling Projects: You support and independently deliver a range of data science engagements, applying statistical and analytical skills to real client problems with a focus on accuracy and clear interpretation. Translate Outputs Into Insight: You take model outputs and draft clear, accessible summaries and narratives that connect findings to media budget decisions, ready for review and client presentation. Apply AI to Data Science Workflows: You use Claude and other AI tools as a standard part of your workflow, finding practical ways to accelerate code development, documentation, and output communication. Contribute to Practice Development: You support the development of Brainlabs' data science capability through documentation, process improvement, and sharing what you learn across the team. Who you are A Rigorous and Curious Data Scientist: You have hands-on experience with Marketing Mix Modelling or related statistical modelling, including working knowledge of Meridian, Robyn, and/or PyMC, and you care deeply about getting the analysis right — not just delivering an output. Technically Proficient: You are experienced in Python and comfortable working with GCP, with a solid understanding of Bayesian statistics and marketing attribution concepts. A Practical AI User: You use AI tools in your day-to-day work, with a habit of exploring how they can improve your outputs or speed up your workflow. Developing as a Communicator: You are building your ability to explain technical concepts clearly to non-technical audiences, and take feedback on how to make your outputs more accessible. Detail-Oriented: You take pride in the accuracy and rigour of your work, and apply a consistent quality check to everything you deliver. Curious and Motivated: You are genuinely interested in the intersection of data science and marketing effectiveness, and proactively develop your skills beyond what the immediate job requires. How you succeed Modelling Quality: The workstreams you own within MMM and other projects meet the quality standard set b…
