Media Buyer, Meta Ads Manager (B2C Health App)
About ONU Health
ONU Health is an AI-powered Health OS for preventive health.
We are building a platform that combines wearable data, lifestyle signals, medical documents, health history, and AI to help people detect risks earlier, understand their health better, and take action before small issues become serious problems.
Our goal is to create one personal health account for every person and change healthcare the way online banking changed finance: making health proactive, understandable, and personalized.
We are looking for a Media Buyer / Facebook Ads Manager who can help us build Meta Ads into one of the core acquisition channels for ONU Health.
This is not a role for someone who simply “launches campaigns.”
We are looking for someone who understands creative testing, paid acquisition, performance data, funnels, and consumer psychology.
Role
This role is for a strong Meta Ads / Facebook Ads Manager / Media Buyer who wants to take ownership of paid acquisition for a fast-growing AI health startup.
You will be responsible for planning, launching, optimizing, and scaling paid campaigns across Facebook and Instagram, with a strong focus on testing creatives, hooks, audiences, landing flows, and app subscription funnels.
ONU Health operates at the intersection of health, AI, wearables, prevention, and consumer subscription products. This means our ads need to do more than generate clicks — they need to attract high-quality users who understand the value of prevention and are willing to engage with the product.
For us, paid ads are a system for learning:
Which user pains are strongest
Which hooks create curiosity
Which creatives drive installs
Which messages lead to activation
Which audiences have the best retention
Which campaigns bring paying users, not just cheap traffic
How to scale without destroying unit economics
Key Responsibilities
Launch, manage, and optimize paid campaigns on Meta Ads: Facebook and Instagram
Build and improve campaign structures for app acquisition and subscription growth
Test different audiences, creatives, hooks, angles, offers, and landing flows
Optimize the funnel from impression → click → install → onboarding → activation → subscription
Track and analyze key metrics: CPM, CTR, CPC, CPI, CPA, CAC, ROAS, retention, trial conversion, paywall conversion, and LTV
Create and manage a structured creative testing system
Work closely with the founder, product, and design team to develop high-performing ad creatives
Write and test UGC-style scripts, ad hooks, captions, CTAs, and landing page angles
Use AI tools to generate ad concepts, variations, scripts, and creative ideas
Analyze competitors in health, wellness, AI, longevity, fitness, and preventive care
Prepare weekly performance reports with clear conclusions:What worked
What failed
What we learned
What we test next
Manage budgets responsibly and scale winning campaigns without losing acquisition quality
Continuously improve targeting, creative strategy, campaign structure, and funnel performance
What We’re Looking For
2–4+ years of experience in media buying / paid social / performance marketing
Strong hands-on experience with Meta Ads Manager
Experience running campaigns on Facebook and Instagram
Understanding of mobile app acquisition and subscription funnels
Ability to optimize not only for clicks or installs, but for activation, retention, and revenue
Strong knowledge of creative testing, UGC-style ads, hooks, angles, and direct response marketing
Analytical mindset and ability to make decisions based on data
Experience with A/B testing creatives, audiences, copy, CTAs, and landing pages
Understanding of CAC, ROAS, LTV, CPI, CPA, CTR, CPM, and conversion rates
Ability to work fast, independently, and without waiting for perfect instructions
Startup mindset: ownership, speed, testing, learning, and iteration
Careful attitude toward budget — treating company money as your own
Big Plus
Experience with health, wellness, fitness, longevity, AI, or mobile apps
Experience scaling B2C subscription products
Experience with app tracking tools such as RevenueCat, AppsFlyer, Adjust, Firebase, or Amplitude
Experience with Apple Search Ads or TikTok Ads
Experience creating UGC scripts, video concepts, hooks, and creative briefs
Experience working with AI creative tools such as ChatGPT, Midjourney, Kling, Runway, HeyGen, CapCut, Canva, or similar
Understanding of consumer psychology around sleep, stress, energy, weight, biomarkers, longevity, and preventive health
Experience working with small budgets and fast testing cycles
Experience building performance dashboards or structured reporting systems

Who We’re Looking For Personally
We are looking for someone who:
Thinks like a builder, not just a campaign manager
