The Role

We're looking for a Senior GTM Growth Manager to join a team that operates with the pace and mindset of a startup within Pantheon. You'll help identify, develop, and scale growth opportunities while bringing innovative, differentiated solutions to market.

This role is ideal for someone who thrives in ambiguity, thinks in hypotheses, and enjoys turning market signals into actionable GTM strategies. As a member of this small, startup-style growth team, you'll partner closely with Product Marketing, Sales, and Product to better understand customers, test new approaches, and build repeatable GTM strategies that accelerate growth.

This is not a traditional demand generation role. We're looking for a builder who can combine strategic thinking with hands-on execution. Someone who can analyze customer feedback, sales conversations, and market signals to continuously improve our GTM approach.
