• Follow and promote data mesh principles around decentralised data ownership and ‘data as a product’
• Promote and uphold privacy-by-design principles, ensuring sensitive data is managed in strict compliance with established security and privacy standards
• Increase data literacy of the engineering organisation by hosting training and mentoring other engineers (both less experienced data engineers and software engineers)
• Help advance agentic systems tailored for data engineering through the creation of specialized skills and agents.

• Consistent track record of successful data projects delivered and managing their lifecycle
• Potential to build rock-solid Python applications - writes understandable and maintainable code
• Experience with cloud data technologies (AWS, GCP, or Azure Cloud), such as Redshift, Spark, Trino, Iceberg, Airflow.
