• Large Dataset Analysis – Extensive experience analysing, interrogating and validating large, complex datasets, identifying anomalies and ensuring data integrity across AI-driven solutions.
• Semantic Layer Development – Collaborate with business domain experts to design, build and optimise semantic layers, working closely with Data Engineering to improve performance and scalability.
• Quality Assurance – Significant experience testing, validating and quality assuring data products and AI-generated outputs, with exceptional attention to detail and a critical eye for accuracy.
• Results Ownership – Confident taking accountability for data quality and formally signing off whether AI-generated insights meet business and delivery standards.
• AI & Machine Learning Lifecycle – Previous experience supporting AI/ML initiatives and AI agents from development through to deployment, with an understanding of model validation and continuous improvement.
• SQL Proficiency – Strong working knowledge of SQL for analysing, interrogating and validating large datasets.
• Stakeholder Engagement – Partner with business stakeholders to understand key business questions and translate requirements into trusted analytical models.
• Adaptability – Comfortable working in an agile environment where priorities evolve, AI capabilities mature and continuous learning is encouraged.
