• Automate manual Finance processes by developing reliable, tested and monitored jobs that can be operated and supported effectively.
• Implement reconciliations and data controls to identify missing or incomplete records, duplicates and breaks, and produce clear exception and break reporting.
• Ingest and process external files and feeds, including data received over SFTP and in formats such as CSV and XML.
• Investigate data and reconciliation issues, trace discrepancies through source systems and pipelines, and explain P&L or cash breaks to relevant Finance stakeholders.
• Develop and maintain serverless ETL solutions on AWS, using infrastructure as code and CI/CD practices to support consistent, controlled releases.
• Apply strong SQL and Python-based data processing to transform, validate and reconcile data accurately and efficiently.
• Work with Finance and technology stakeholders to understand requirements, improve existing workflows and deliver maintainable solutions with appropriate controls.
• Contribute to improving the reliability, observability and quality of Finance data flows as the business and its systems evolve.
