Junior Media Buyer
IM8 is a next-generation health and longevity brand co-founded by David Beckham and Prenetics (NASDAQ: PRE), on a mission to make world-class nutritional science accessible to everyone. Launched in late 2024, IM8 grew Q1 2026 revenue nearly 6x year-over-year to $33.8M, and the company has raised full-year 2026 IM8 revenue guidance to $190M–$210M. Over 60% of revenue is generated outside the US. We ship to 43 countries, and our athlete partner roster includes David Beckham, Giannis Antetokounmpo, Aryna Sabalenka, Ollie Bearman, and Inter Miami CF.
We are built on science, not story — our flagship Daily Ultimate Essentials carries 90 active ingredients, we run randomized controlled trials on our products, and we hold a clinical-grade standard in a category notorious for shortcuts.
Our business is subscription at its core. Every basis point of NRR we add compounds — into LTV, into payback, into the ability to outspend everyone else on acquisition. Retention isn't a department at IM8. It is the model.
POSITION OVERVIEW
We're hiring a Junior Media Buyer to own day-to-day execution of our Meta paid social program across global markets. You'll sit at the centre of our growth engine — partnering with the paid creative team to ship and iterate on high-velocity creative, managing spend across multiple markets, and obsessing over the unit economics that drive a healthy subscription business.
This is a hands-on, in-platform role. You'll spend most of your day in Meta Ads Manager, in our BI dashboards, and in tight feedback loops with creative strategists, motion designers, and the analytics team. You'll be coached by senior buyers and have a clear path to grow into a Media Buyer / Growth Lead role.
We're looking for someone who has cut their teeth on a DTC Shopify brand, ideally with a subscription model, and is fluent in the language of CAC, LTV, contribution margin, and creative testing. You think in cohorts, not clicks. You see creative as the most important lever in paid social — and you know how to brief, test, and scale it.
KEY RESPONSIBILITIES
- Own campaign execution. Build, launch, pace, and optimise Meta paid social campaigns across our priority global markets.
- Partner with creative. Brief new concepts, run structured creative tests, kill losers fast, and scale winners aggressively.
- Hit growth targets. Deliver weekly and monthly CAC, ROAS, and new-customer acquisition targets, with a clear line of sight to LTV and payback.
- Protect data integrity. Maintain clean account architecture, naming conventions, and UTM taxonomy so the data we feed into BI is trustworthy.
- Report with clarity. Report performance weekly to the Head of Performance with clear, prioritised learnings and next-week test plans.
- Stay platform-current. Track platform changes (Advantage+, Andromeda, attribution updates) and translate them into operational decisions.
WHAT SUCCESS LOOKS LIKE
- You think in CAC : LTV — blended vs. paid CAC, payback period, contribution margin, and bidding against an LTV target rather than last-click ROAS.
- You write tight, hypothesis-driven creative briefs, read the data, and feed clean learnings back to the creative team.
- You run disciplined in-platform execution: campaign structure (CBO/ABO, Advantage+ Shopping, audience segmentation by market/funnel stage), budget pacing, bid strategy, and methodical scaling.
- You triangulate measurement across Meta in-platform, GA4, Triple Whale / Northbeam, and Shopify backend truth.
- You run a clean operating cadence: daily pacing checks, weekly performance reviews, monthly creative refresh cycles, and reporting a Head of Growth can read in 60 seconds.
REQUIREMENTS
- 1–3 years hands-on Meta Ads buying experience at a DTC brand, performance agency, or in-house growth team.
- Direct experience running paid social for a Shopify (ideally Shopify Plus) brand. You know the Shopify → Meta data stack: CAPI, Pixel, Shopify native integration, UTM hygiene.
- Demonstrable experience executing globally at scale across multiple markets, currencies, and time zones — not just one home market.
- Experience working alongside a dedicated paid creative team (creative strategists, editors, motion designers) and contributing to a structured creative testing pipeline.
PREFERRED / NICE TO HAVE
- Subscription experience is a strong bonus — you understand conversion rate analysis, churn, LTV cohorts, and how subscription economics change the way you bid.
- Health, wellness, supplements, or personal care category experience.
- Exposure to Google Ads, TikTok Ads, YouTube, or AppLovin AXON as a secondary channel.
- Familiarity with incrementality testing, geo-lift, or holdout methodology.
- Comfort with SQL, Looker, or Mode for pulling your own numbers when needed
