• Develop and deploy AI/ML models and LLM-based workflows — including RAG pipelines, prompt engineering, and agent orchestration — to generate media performance insights and activation intelligence.
• Build and maintain APIs and backend services that surface media data and AI-generated insights to business users and downstream applications.
• Implement monitoring, logging, and alerting for pipelines and models to ensure reliability, performance, and cost-efficiency in production.
• Collaborate with Product Owners, Engineering, and Architects across Marketing & I&A Products to translate business requirements into scalable, reliable technical solutions.
• Contribute to platform architecture decisions including infrastructure-as-code (Terraform), containerisation (Docker), and CI/CD practices.
• Write clean, tested, well-documented code; participate in code reviews, sprint ceremonies, and knowledge-sharing across the team.

• Exposure to AI/ML engineering — LLM integration, prompt engineering, RAG pipelines, or agent-based architectures.
• Experience with data integration patterns: REST APIs, streaming, orchestration (Airflow/Cloud Composer), and DBT.
• Solid software engineering fundamentals: Git, CI/CD, testing, Docker, and Terraform.
• Strong communication skills; able to work cross-functionally and translate technical topics to business stakeholders.
• Intellectual curiosity and a bias for learning in a fast-moving data and AI environment.
