Senior Sales Engineer - Prefect

Prefect Builds Automation for an Unpredictable World

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.

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

Role Summary

Prefect acquired Dagster this summer, and 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 FastMCP, our open-source MCP framework, which sits inside many production agent stacks. Much of what a sales engineer does here is demonstrate the art of the possible.

You'll be a Senior Sales Engineer on the Prefect subject-matter-expert pod, reporting to Wayne Grigsby (Sales Engineering Lead). This is a pre-sales seat where 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 procurement.

What You'll Do

• Own the technical side of enterprise deals: Advise prospects and demonstrate the value of our platforms from discovery through close.
• Distill the use case: Figure out how our products fit together to solve messy architectural requirements and help prospects validate their approach.
• Sell across the platform: Span conversations across Prefect, Dagster, FastMCP, hybrid architecture, and AI governance.
• Turn field signal into product direction: Carry market feedback and product insights into our GTM-engineering partnership channels with evidence.
• Build demo assets: Create demo environments, architecture diagrams, competitive battlecards, contributions to internal repos, personal projects, and occasional blog posts.
• Contribute and advocate: Champion the culture, speak up early when projects go sideways, and help fix them.

Your Qualifications

1. 3+ years of engineering experience: Building real solutions in data engineering, DevOps, software engineering, or data science. Python is our house language.
2. 2+ years in a customer-facing role: Deep discovery skills and the habit of uncovering the real problem before proposing anything.
3. Curiosity first, then creativity: Taking things apart to see how they work, going beyond the docs, and building novel solutions or demos.
4. Clear technical communication: Ability to make a senior platform engineer trust you and understand hard technical concepts clearly.

Nice to Have:

• 2+ years of prior sales engineering experience.
• 2+ years of enterprise infrastructure depth in at least one major cloud (Azure, AWS, GCP) with comfort in Kubernetes, networking, IAM, service mesh, and Postgres.
• Experience with orchestration tooling as a user, builder, or seller (Prefect, Dagster, Airflow, Temporal, Step Functions, etc.).
• Fascination with AI and tinkering with MCP, agents, or LLM applications.

• Remote-first team with a flexible-first culture
• Equity stock options
• 401(k) with 5% company match (vests immediately)
• Unlimited PTO
• Medical, Dental, and Vision insurance
• Generous parental leave
