As a Senior Software Development Engineer, you will own the technical design and execution for core components of Workday's distributed tracing platform, built on ClickHouse and/or Grafana Tempo and backed by a big-data pipeline (Kafka, Spark/Flink, Iceberg, S3). We own the libraries, distributed services, and infrastructure that power ingestion, storage, and query across the observability stack - Iceberg, ClickHouse, Tempo, Grafana, S3, Kafka, and Elasticsearch serving traces, metrics, and logs for every workload at Workday.
