We help clients understand what has happened and why and how to shape the marketing strategies that shape their future.

  • Design and implement feedback loops to drive better data quality and commercial outcomes. 

  • Apply supervised and unsupervised learning techniques to build scalable, production-ready solutions. 

  • Collaborate with developers to ensure robust, high-availability of model predictions in a microservices architecture. 

  • Create and maintain data pipelines and monitoring tools. 

  • Communicate technical insights to non-technical stakeholders, including senior commercial leaders. 

What You’ll Bring 

  • 5+ years of experience in data science experience. 

  • Experience with supervised learning, unsupervised anomaly detection, or similar quality assurance domains. 

  • Strong proficiency with python or a similar language. 

  • Proven experience of automating model training pipelines using cloud services. 

  • Working experience/knowledge of CI/CD pipelines, IAC and git version control. 

  • Excellent problem-solving skills and a collaborative mindset. 

  • A strong sense of ownership over data science products. 

  • Experience in industries with large consumer marketplaces (e.g. programmatic media, travel, financial services) is a plus. 

  • Knowledge or experience with Kafka is a plus. 

Our Tech Stack 

  • AWS (Sagemaker, S3, lambda), PostgreSQL, Grafana, Kafka, Redshift. 

  • Note: The company is transitioning towards Azure for new development. 

Why Join Us? 

At Kantar, you’ll be part of a global leader in data, insights, and consulting.
