• Degree in Computer Science, Data Engineering, Information Systems, or a related discipline
• At least 8 years of experience in data engineering, ETL/ELT development, or data platform roles
• Strong hands-on experience designing and building data solutions on AWS
• Strong experience with AWS services such as Glue, Step Functions, Lambda, and S3
• Hands-on experience with Apache Iceberg or similar open table formats
• Strong understanding of modern data lakehouse architecture and concepts
• Experience designing scalable and reliable data pipelines
• Strong understanding of data quality, validation, monitoring, and governance practices
• Experience writing production-quality code and deploying applications on cloud infrastructure
• Experience with CI/CD and infrastructure-as-code practices
• Strong understanding of Apache Iceberg capabilities and/or S3 table optimisation techniques
• Strong communication skills, with the ability to explain technical concepts to non-technical stakeholders
