Senior🎓
Top SchoolJethro Kairys is a Staff Data Engineer based in Melbourne with 15+ years designing and operating scalable data and developer platforms that power 200+ users and 50+ data products across utilities, finance and telco. He combines hands-on expertise in Python, Spark, Kubernetes, Terraform, GCP and AWS with product-led platform thinking, having delivered ANZ’s first internal data mesh and enterprise-wide platform adoption. Jethro has repeatedly reduced operational cost and cognitive load—most notably a Kubernetes migration at nbn that cut compute costs by ~40%—while enabling self-service analytics and CI/CD for cross-functional teams. He has taken startups to scale (Future Grid) and built secure, governed ingestion and PII frameworks for regulated environments, blending electrical engineering roots with cloud-native engineering practice. Known for shifting teams from point solutions to reliable platform products, he’s equally comfortable architecting domain models, shipping reusable IP, and mentoring squads to align technical roadmaps with business outcomes.
