About Mito Health
Mito is reimagining preventive healthcare. We offer the most advanced blood testing panel on the market—over 100+ biomarkers, nationwide lab access, 1:1 MD consults, and AI-personalized plans. 

Think: your annual physical, but deeper, more actionable, and with real doctors guiding your health journey.

We’re backed by Y Combinator, Balaji Srinivasan, and a who’s who of Silicon Valley. As we scale toward eight figures in ARR, we’re building a high-performing growth team and looking for a creative, data-driven intern to join us in LA this summer.

 

What You’ll Do

📈 Content Strategy & Creation

  • Develop a content roadmap for Instagram and TikTok, aligned with our brand voice and mission.
  • Produce short-form videos (Reels, TikToks, YouTube Shorts) that educate, inspire, and drive action.
  • Write sharp copy for blogs, ads, and email campaigns that resonate with both consumers and businesses.
  • Craft messaging that empowers users to take charge of their health and demystifies longevity science.
  • Stay plugged into wellness, functional medicine, and performance marketing trends to keep our content fresh.

🎯 Campaign Execution & Channel Experimentation

  • Work alongside our Head of Growth and executive team on full-funnel campaigns targeting key ICPs.
  • Help us test new growth channels—from influencer campaigns to podcast and newsletter sponsorships.
  • Source, pitch, and coordinate with influencers and creators aligned with our values.
  • Support in-person events, pop-ups, and community activations in the LA (and beyond!) wellness space.

🧠 Community Growth & Engagement

  • Build and nurture a loyal online community by responding to DMs and comments with care.
  • Leverage UGC and collabs to build trust and expand reach.
  • Identify and implement strategies to grow followership across core platforms.
  • Tap into micro-communities and thought leaders in health, performance, and longevity.

📊 Analytics & Attribution

  • Help track attribution across all marketing efforts: Where did leads come from? What did they cost? What did they convert into?
  • Analyze performance metrics (reach, engagement, CTR, ROAS, etc.) to inform future creative and spend decisions.
  • Help run A/B tests on content, hooks, hashtags, and posting strategies to maximize engagement.
  • Provide weekly performance snapshots and monthly learnings to guide strategy.

🚀 Performance Marketing & Scaling

  • Assist in scaling our paid media strategy across Meta, Google, and emerging platforms.
  • Help drive efficiency in spend while expanding reach and lowering CAC.
  • Contribute ideas and assets for new creative testing loops—everything from ad copy to UGC iterations.
     

Who You Are

  • A natural storyteller who knows how to turn science-backed insights into scroll-stopping content.
  • Obsessive about Instagram and TikTok, with an eye for trends and transitions.
  • Analytical by nature — you love looking at numbers and optimizing what’s working.
  • Comfortable using Canva, CapCut, Google Suite, and performance dashboards.
  • A health/wellness nerd who loves learning about biohacking, longevity, and high-performance living.
  • Proactive, scrappy, organized, and excited to get your hands dirty in a startup environment.

Preferred Experience

  • 1+ years managing Instagram or TikTok for a brand or creator.
  • Strong video editing, caption writing, and aesthetic sense.
  • Familiarity with marketing tools like Later, Hootsuite, or Notion.
  • Previous exposure to growth, content marketing, or paid ads is a plus.
