About the Role

Justworks is rethinking how we drive growth across the entire prospect and customer journey. Our goal is to build an intelligent, AI-powered growth engine that helps us identify and engage prospective customers, convert demand more effectively, and support customers as their businesses grow.

We're looking for a Senior Manager, Growth Automation & AI to lead the next evolution of our Marketing Operations capabilities.

This role combines deep marketing expertise, a strong understanding of customer growth, and the technical vision to fundamentally change how work gets done.

You'll work closely with leaders across Marketing, Sales, Product, Customer Success, Analytics, and GTM Engineering to turn business opportunities into scalable capabilities.

Your mission is to build the systems that drive customer acquisition, engagement, and expansion across Justworks.
