• Help develop and maintain messaging frameworks aligned with the company’s narrative
• Draft and edit CEO social media posts for LinkedIn in coordination with the VP

• Excellent writing and editing skills with ability to draft a press release, a CEO LinkedIn post, and an interview prep doc all in the same morning
• Experience supporting C-suite executives with communications materials and media preparation
• Comfort working in a fast-paced startup environment where priorities shift quickly and resourcefulness matters more than process
