What You Will Do:
- Own the end-to-end self-serve acquisition funnel, scaling top-of-funnel demand through social, content, and partnerships while systematically optimizing activation and conversion.
- Design and execute data-driven growth experiments to refine the PLG motion and identify high-intent signals for enterprise expansion.
- Craft compelling brand narratives and high-quality content that builds trust with professionals, while representing the company globally through live demos and user engagement.
The ideal candidate:
- Has 3+ years of experience in senior GTM or growth marketing roles, with a proven track record of building or scaling PLG motions at high-growth startups.
