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, competitors for eight years, 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 think of our culture as the operating system of the company. We’ve carefully created a supportive, high‑performance environment that empowers our team to do the best work of their careers, have meaningful impact, and continue growing personally and professionally. We’re a remote‑first team that values high standards, ownership, and thoughtful collaboration.

Prefect acquired Dagster this summer. Our sales engineers now sell three things. Prefect Cloud. Dagster+.

And the next generation of AI tooling we’re building across both: governed access to tools and data for agents, and durable workflows where agents and humans do the work together.

We’re also selling something that isn’t on a pricing page. FastMCP, our open‑source MCP framework, sits inside a lot of production agent stacks, so teams come to us for how the whole thing should fit: the data layer, the orchestration layer, the context layer, and how agents and humans operate across all three. Much of what a sales engineer does here is demonstrate the art of the possible.

You’re a Senior Sales Engineer on the Prefect subject‑matter‑expert pod, reporting to Wayne Grigsby, Sales Engineering Lead. The pod sits alongside our Dagster pod, and both roll up to George Coyne, Director of Sales Engineering, who runs the function end to end, pre‑sale and post‑sale.

This is a pre‑sales seat. You pair with account executives on new business from the first technical call to signature: discovery, tailored demos, proofs of concepts, security and architecture reviews, and the slow procurement stretch at the end. You’ll work across the whole platform. Your job is to figure out how the pieces fit for a given customer, then prove it.

• Own the technical side of enterprise deals. From discovery through close: advising prospects, presenting and demonstrating the value of our platforms from a technical perspective.

• Distill the use case. Most prospects don’t arrive with a clean requirement. They arrive with a data platform, a pile of tools, a team of engineers and users expecting answers, and a budget. You figure out how our products fit together to solve for their use case, then help them validate the approach.

• Sell across the platform. A single conversation can span Prefect, Dagster, FastMCP, hybrid architecture, and AI governance, often with a team that knows where it wants to end up but not how to get there.

• Turn field signal into product direction. Sales engineers are the closest thing to a market pulse this company has. You’ll carry what you hear into our GTM‑engineering partnership channels, with…
