About the Role

Description

Creative Marketing InternTemporary: Approximately 3 Month Duration New York, NY


About the Position:


Mountainside Treatment Center is looking for a recent college graduate to join our New York City marketing team for a full-time, three-month internship starting as soon as possible. This role leans creative: most of your time will go to video editing, clipping content for social media, and graphic design. You’ll also get hands-on exposure to the rest of our marketing work, including digital advertising, content strategy, social media management, our website, and events. 


You’ll work closely with a small, mission-driven team that creates content for people looking for help with addiction and for the families supporting them. If you have a good eye, like learning by doing, and want your first role out of school to reach people who need it, this is a strong fit.

  • Work with our senior graphic designer on event materials, print pieces, and other visual assets as needed 
  • Write and refine social media captions tailored to each platform 
  • Organize and maintain a library of footage, clips, and templates so the team can find and reuse content quickly 
  • Spot opportunities to repurpose existing content into new formats, edits, and creative concepts 
  • Assist with social media content planning, organization, and scheduling 
  • Track how videos and posts perform and share what’s working with the team

  • Get exposure to the wider marketing team’s work, including paid media, SEO and website updates, PR, and events, and pitch in on those projects as needed 

Qualifications:

  • Recent college graduate with a bachelor’s degree in Marketing, Communications, Film, Graphic Design, or a related field 
  • Available to work in person, Monday–Friday, 9:00 AM – 5:00 PM for the full three months, starting as soon as possible 
  • Hands-on experience with video editing tools such as Adobe Premiere Pro, CapCut, or similar software 
  • Working knowledge of design tools such as Adobe Photoshop, Illustrator, or Canva 
  • Experience with After Effects or other motion graphics tools is a plus
