Proven experience building and maintaining Airflow pipelines (Cloud Composer preferred). Strong programming skills in Python and solid SQL expertise. Experience with PySpark and distributed/large‑scale data processing systems. Good understanding of data modelling and modern ETL/ELT design patterns. Experience working with Git‑based workflows in collaborative engineering environments. Strong communication skills and ability to work effectively with both technical and non‑technical stakeholders. Experience working in Agile delivery environments. Nice to have: experience with Dataproc, Dataplex, Great Expectations or similar data quality tools, AWS services (S3, MWAA, Databricks), and cloud migration projects. Exposure to media, streaming, or large‑scale consumer platforms is a plus. Benefits Competitive compensation aligned with senior‑level expertise. Flexible working arrangements (remote/hybrid depending on team setup). Opportunity to work on a large‑scale cloud migration and modern data platform. Career growth through exposure to complex, high‑impact data products. Ongoing training, mentoring, and professional development support.
