  • Coordinate development activity across the delivery lifecycle, ensuring high-quality outcomes and on-time delivery.

  • Contribute to architecture and technical design discussions, ensuring solutions align to business goals and data platform standards.

  • Maintain and improve the health and performance of the data estate through optimisation, monitoring, and continuous improvement.

  • Produce and maintain clear technical documentation for changes, releases, and data processes.

  • Troubleshoot and resolve data warehouse incidents, including implementing hotfixes where required.

  • Provide third-line support within agreed service management processes, supporting L1/L2 teams where needed.

  • Engage stakeholders to gather requirements and translate them into fit-for-purpose technical solutions.

  • Mentor and guide other developers, driving knowledge sharing and raising engineering standards.

  • Identify opportunities to improve development processes, tooling, and ways of working.

    Proven senior-level development experience in data warehousing environments.

  • Strong understanding of data warehouse architecture, design patterns, and SDLC best practices.

  • Hands-on expertise across data warehousing concepts including physical modelling, ETL/ELT, CDC, reconciliation principles, semantic layers, and rules engines.

  • Strong SQL skills and experience with Python in data engineering contexts.

  • Experience with modern data platforms and tooling (e.g., Snowflake, AWS, Terraform).

  • Comfortable working in Agile/Scrum delivery environments.

  • Experience with version control (e.g., Git) and good engineering practices.

  • Excellent problem-solving skills and ability to communicate technical concepts clearly to non-technical stakeholders.

  • Collaborative mindset and an ownership-driven approach to delivery and operational support.

  • Industry experience in insurance or financial services (or similarly regulated environments).


Desirable but Not Essential

  • Experience with CI/CD pipelines and cloud-native deployment patterns (AWS/Azure/GCP).

  • Experience building monitoring, automated testing, or reporting/dashboarding/data feed solutions.

  • Knowledge of Data Vault 2.0.
