About the Team The Data Platform and Observability Engineering (DPOE) team is building Workday’s next-generation, multi-petabyte-scale Observability Platform. We are a distributed team responsible for the libraries, distributed services, and infrastructure that power observability across Workday. Our stack includes Iceberg, ClickHouse, Tempo, Grafana, S3, Kafka, Elasticsearch, and LangSmith for LLM/agentic tracing and evaluation. Together, we support traces, metrics, logs, and LLM/agent observability across Workday workloads at scale. About the Role As a Senior Software Development Engineer, you will own the technical design and execution of core components of Workday’s distributed tracing platform, built on ClickHouse and/or Grafana Tempo and backed by a big-data pipeline using Kafka, Spark/Flink, Iceberg, and S3. This is a hands-on role where you will solve multi-petabyte-scale challenges, optimize low-latency infrastructure, and shape the future of Observability AI by extending distributed tracing to LLM and agentic workflows with LangSmith and LangChain, enabling visibility into agent execution, tool calls, and prompt/response chains.
