  • Design, build, and operate services and pipelines that power analytics data ingestion, schema management, and delivery into Databricks.
  • Modernize legacy platform components by migrating services, libraries, and deployment workflows to modern Java and application standards.
  • Build automation, CI/CD flows, and scenario/integration test coverage to make platform changes safe and repeatable.
  • Design and maintain production infrastructure in AWS using Infrastructure as Code tooling such as Terraform.
  • Improve data quality through stronger schema validation, metadata capture, lineage tracking, and operational guardrails.
  • Build tooling and paved paths that help internal customers migrate to new ingestion and schema standards.
  • Collaborate with cross-functional teams to prepare design documents, rollout plans, and implementation strategies for platform changes.
  • Monitor live systems, investigate incidents, and participate in the on-call team providing 3rd-line support for live analytics services.
  • Support performance, reliability, and cost optimization across ingestion and processing flows.

  • Commercial experience with Spark/PySpark.
  • Effective communication and teamwork skills.

  • Familiarity with Golang for internal tooling or automation.
  • Experience with infrastructure monitoring and on-call practices using tools such as Datadog and PagerDuty.
