You

You’re an endlessly curious Social Channels Manager with a deep connection to the cultural zeitgeist and a pulse on social channel trends and performance. You’re passionate about shaping health culture and believe that storytelling can spark personal transformation.

You understand and synthesize performance data into actionable insights, then plans for execution. 

You’re a cross between a channel strategist, performance analyst and content expert—with a belief that content isn’t just a deliverable, it’s a vehicle for meaning. You thrive in a fast-paced, feedback-rich environment and believe risky ideas are worth pursuing.
