Developer Success Engineer (UK-Based) - Prefect

About Prefect

Prefect builds automation for an unpredictable world. The last decade of automation was about protecting workflows from unpredictability; in the agentic era, unpredictability is the point. Our mission is to give people confidence in automated work, whether that work is a mission-critical data pipeline or a fleet of AI agents.

In August 2026, Prefect and Dagster joined forces to build the next generation of automation infrastructure. Today, our ecosystem includes Dagster, the data platform; Prefect, the agent platform; and FastMCP, the leading open-source developer framework for the MCP ecosystem. Together, our open-source and commercial products are trusted by Fortune 500 companies, data innovators, and high-growth technology companies around the world.

We’re a remote-first team that values high standards, ownership, and thoughtful collaboration.

Role Summary

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.

The team is investing in agent-based automation for routine support work, which is moving the engineering focus toward complex diagnosis and escalation. This role is well suited to an engineer who wants to build deep expertise in orchestration and data platform environments and apply it directly with customers.

What You'll Do

• Clear the failure state, and prevent the next one. Diagnose problems across Prefect and Dagster installations, integrations, deployments, and the cloud and container environments they run in. Find the underlying "why" so your first response resolves the question and pre-empts follow-ups. Turn what you learn into docs, debugging resources, and tooling that deflect repeat submissions.
• Own what's ours; say no clearly to what isn't. Take full accountability for root causes inside our products' domain of control. For problems outside our Scope of Support, issue a principled no that still gives the customer a way forward.
• Support your findings, and ask customers to support theirs. Back every diagnosis with evidence and logic. Assume the customer is the expert on their own stack, ask for what you need to troubleshoot both sides of an issue, and explain why you need it.
• Give the best possible update every time, and say so when you're still building it. When an issue needs to be escalated, stay as the customer's single point of contact, keep them updated on a regular cadence, and close the loop.
• Feed the product. File reproducible product issues and surface recurring failure patterns to Engineering and Product.

Timezone & on-call: Available to work 09:00 – 18:00 CET (UTC ± 2) and participate in 24/7 on-call rotations.

Your Qualifications

Must have:

• Python fluency at the level of reading and debugging complex codebases.
• Hands-on experience running workloads in at least one major cloud provider and in containers or Kubernetes.
• Experience with workflow orchestrators (Prefect, Dagster, Airflow, or comparable) and strong interest in data engineering.
• Proven track record of technical, customer-facing work (support, solutions engineering, developer relations, or similar).
• Clear written communication to explain root causes to senior engineers and earn trust.

Nice to have:

• Direct experience with Prefect or Dagster.
• A history of open-source contributions.
• SQL and data warehouse familiarity.
• Experience building support tooling or automation.
