Developer Success Engineer (UK-Based)

Developer Success is the technical support function for Prefect's customers across the Prefect and Dagster product lines. Its mission is to resolve customer technical issues with the least possible customer effort, and to prevent those issues from recurring. We are hiring a Developer Success Engineer to work the combined Prefect and Dagster support queue. You will diagnose and resolve technical issues in customer environments, own each issue through resolution, and contribute to the documentation, tooling, and product feedback that reduce future volume. You will be trained on both Prefect's and Dagster's products. Timezone & on-call: Available to work 09:00 – 18:00 CET (UTC ± 2) and participate in the 24/7 on-call rotations.

Requirements

Python fluency at the level of reading and debugging someone else's code, not only writing your own; Hands-on experience running workloads in at least one major cloud and in containers or Kubernetes, enough to troubleshoot a deployment you didn't build; Experience with a workflow orchestrator (Prefect, Dagster, Airflow, or comparable) and a strong interest in the data engineering space it lives in; A track record of technical, customer-facing work: support, solutions engineering, developer relations, or similar; Clear enough written communication to explain a root cause to a skeptical senior engineer and earn their trust
