At the core of this mission sits our data platform. We’re great believers in powerful, real-time analytics and empowerment of the wider business. We optimise for simplicity and re‑usability – all our data lives in one place and is made available via our data warehouse in Snowflake.

• Support the building of robust data models downstream of backend services (mostly in Snowflake) that support internal reporting, financial and regulatory use cases.
• Focus on optimisation of our Data Warehouse, spotting opportunities to reduce complexity and cost.
• Help define and manage best practices for our Data Warehouse. This may include payload design of source data, logical data modelling, implementation, metadata, and testing standards.
• Set standards and ways of working with data across VXBS, working collaboratively with others to make it happen.
• Take established best practices and standards defined by the team and apply them within other areas of the business.
• Investigate and effectively work with colleagues from other disciplines to monitor and improve data quality within the warehouse.
• Contribute to prioritisation of data governance issues.

You should apply if:

• You have experience and a passion for Data Modelling, ETL projects, and Big Data as a developer or engineer
• You have good experience in Python, Java or similar languages
• You have proven experience with AWS
• SQL and data modelling is second nature to you
• You are comfortable with general Data Warehousing concepts
• You strive for improvement in your work and that of others, proactively identifying issues and opportunities
• You have experience building robust and reliable data sets requiring a high level of control
• You have proven experience with stream technologies like Kafka, Kinesis, Pulsar, etc
• You have experience working with IaC tools such as Terraform, AWS CloudFormation, or Ansible

Nice to haves:

• Any experience working within a finance function or knowledge of accounting.
• Experience working in a highly regulated environment (e.g. finance, gaming, food, health care).
• Knowledge of regulatory reporting and treasury operations in retail banking
• Have previously used dbt, Databricks, or similar tooling
• Experience working with orchestration frameworks such as Airflow/Prefect
