• Contribute to data science and AI initiatives, including Mosaic, Audience Taxonomy, Spend Analytics, embeddings, retrieval-augmented generation (RAG) and prompt engineering, where relevant.

• Collaborate with scrum teams and stakeholders to translate requirements into reliable analytical solutions, document methodologies and communicate findings clearly to technical and non-technical audiences.

What we're Looking:

• 5 years of working experience applying data science and machine-learning techniques to business or product challenges, ideally within marketing analytics, customer segmentation, audience analytics or a related customer-data environment.

• Proficiency in Python and SQL for analysing large and complex datasets, using libraries such as pandas, scikit-learn or similar tools.

• Strong knowledge of statistics, experimentation and machine learning, including regression, hypothesis testing, experimental design, feature engineering, model selection and evaluation.

• Experience working with modern cloud data platforms, such as Snowflake, and the ability to structure and solve complex or ambiguous problems.

• Clear communication, planning and collaboration skills, with the ability to work independently and partner effectively with Data Science, Engineering, Product and business teams across locations, time zones and changing priorities.

Additional Experience That Would Be Valuable:

• Experience with generative AI and large language model applications, including embeddings, retrieval-augmented generation (RAG), vector search or prompt engineering.

• Knowledge of deep-learning techniques or experience working with large-scale datasets.

• Experience developing analytical solutions into repeatable products, capabilities or business processes.

• Exposure to model validation, monitoring and ongoing performance evaluation.or
