Senior Growth Marketing Manager - 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

We are looking for a Senior Growth Marketing Manager to own the path from audience to signup to activated user to qualified pipeline across Prefect, Horizon, and the Dagster funnels. You will own attribution, lifecycle and email, paid and organic acquisition, CRO, and experimentation with dedicated budget and clear targets.

You'll report to our Chief Growth Officer and work daily with Marketing, Sales, and Engineering.

Time zones: Anywhere in the continental US. We're remote-first with a slight preference for candidates near New York, the Bay Area, or Washington D.C.

What You'll Do

• Expand Our Brand Awareness and Pipeline Generation: Own paid and organic acquisition end to end, including budget, channel mix, landing pages, and CRO.
• Make Funnels Scalable and Predictable: Build funnels, loops, and models for highest-priority motions (FastMCP to Horizon, Horizon self-serve signup to activation, website to inbound, open source to Cloud) with owners, baselines, and conversion targets.
• Own Lifecycle: Design and ship onboarding, activation, and re-engagement sequences starting with thousands of Horizon signups. Measure activation lift rather than open rates.
• Experiment Fast: Organize campaign taxonomy, UTM discipline, and HubSpot-to-Salesforce handoffs to run multiple funnel-optimization experiments. Report cost per activated user and pipeline per dollar.
• Route Audience to Product: Turn FastMCP's developer audience into Horizon accounts through in-product paths, docs placements, end cards, and CTAs.

Your Qualifications

Must Have

• 7+ years in growth or demand generation at B2B SaaS or developer-focused companies, with hands-on tool execution experience.
• Proven ability to use channels and campaigns to generate predictable pipeline for sales and self-serve signups.
• Experience owning an acquisition budget and reporting transparently on ROI and failures.
• Built attribution from scratch: campaign taxonomy, UTM structure, and funnel models (HubSpot and Salesforce or close equivalents).
• Lifecycle ownership with measured before-and-after conversion results.
• Comfort working autonomously as an individual contributor.

Nice to Have

• Background at an open-source or developer-tools company.
• SQL proficiency and comfort with BI tools (HubSpot, Salesforce, Amplitude, Common Room, Omni).
• Experience running product-led self-serve funnels alongside enterprise sales-led motions.
• Post-acquisition marketing stack integration experience.

What You'll Get

Perks and Benefits:

• Remote-first team with flexible-first culture
• Equity Stock Options
• 401(k) with 5% company match (vests immediately)
• Unlimited PTO
• Medical, Dental, and Vision insurance
• Generous Parental Leave
• Life Insurance and Disability benefits
• $800/month remote work stipend
