Job description

We want people to experience their healthiest bodies, on their own terms.

To do that, we're closing the data gap that exists in wearables today, gut health and nutrition.

Suna is a wellness wearable for your gut. It listens to your gut around the clock, through sound, and turns what it hears into something you can read every morning. Think of it as the Fitbit for your gut and nutrition. On top of it sits the Oracle, a personal health agent. It joins what the patch hears to the context of your life, what you ate, your calendar, the weather, your email, and talks to you where you already are, on WhatsApp or iMessage. We are a small founding team in London and San Francisco, and we build the device, the models and the app ourselves.

The Role

Most people never get to launch a new category. You do, with the budget and the numbers in your hands: Meta from the first test to real spend, the site, the funnel, and once the app ships, who is using what. If it moved, you will know why, and you will have done it.

You may own

• Meta, end to end: structure, creative testing, audiences, cost caps, scaling.
• What is performing and how to scale it: which ad, which reel, which page, for how long and for whom. Then you change the hook, move the budget, rewrite the page, and come back with the number that moved. Not reports, the next version.
• The signal: Pixel and Conversions API we can trust, and an event schema that survives a wellness domain losing events.
• The site: where people land, how long they stay, where they drop, and the A/B test that settles it. Landing page, waitlist and deposit flow are your funnel.
• Search and the blog: what people type before they find us, the pages that answer it, the ranking to show for it. Suna Digest is yours to grow.
• The app, once live: download to first wear, activation, retention, which features get used. The event plan, the dashboards and the Monday decision.
• The tooling: PostHog or its equivalents, GA4, Meta reporting, the warehouse behind them. You pick the stack and keep it honest.
• The money: CAC by source, payback, deposit to paid, refunds, and the gap between what the platform reports and what actually moved.

You'll fit if

• You have personally run Meta for a consumer brand. Tell us how much a month, and walk us through the account: what won, what fatigued, what you killed.
• You know your creative hit rate and the volume behind it.
• You have stood up an acquisition channel from nothing.
• SQL without asking an engineer. Cohorts, payback and funnels are yours, and you have instrumented a product from scratch.
• You design and read A/B tests and know when to stop one.
• Unreasonable attention to detail. A wrong UTM or a double-firing event never reaches the dashboard.
• AI native. Claude Code is your working day; you automate a chore rather than repeat it.
• You want to be in the room where it is decided, and you want the growth numbers to be yours.
• Run a creative testing pipeline with briefs, editors or creators
• Scaled a Meta account past its first real budget without CAC breaking
• Meta Blueprint certified, or ran paid social at an agency
• Launched a hardware or pre-order product
• Built a UGC or creator pipeline that lasted
• Run TikTok Shop or TikTok ads at real spend
