Johnson & Johnson is looking for a Head of Marketing & Growth to build a predictable, profit-focused growth engine for our multi-country eCommerce stores. This hands-on role is responsible for performance marketing strategy, execution, optimization, and results end-to-end, driving scalable growth through paid media and email.

What You'll Do

Build, launch, and optimize campaigns across Google Search, Shopping, Performance Max, YouTube, Meta, and TikTok.
Run weekly structured testing on audiences, budgets, creatives, landing pages, and offers.
Maintain clean account structures, naming conventions, governance, and change logs.
Expand into additional channels (Pinterest, Reddit, TV/OTT) after core platforms are stable.
Own Klaviyo (or equivalent), including campaign calendar, segmentation, and performance reporting.
Build and optimize lifecycle flows: welcome, browse/cart abandonment, post-purchase, winback, upsell, and cross-sell.
Align email creative and messaging with paid media angles and promotional calendars.
Lead a structured creative system: angles → variations → winners → scale.
Write clear briefs for designers, editors, and UGC creators and manage creative rotation.
Collaborate with CRO/Shopify teams to ensure strong alignment between ads, landing pages, and checkout experience.
Replicate winning campaigns across regions with localized adaptations (currency, shipping, language, seasonality).
Maintain a centralized 'winners library' to ensure learnings scale across stores.
Ensure messaging remains compliant with platform and regional policies.
Own performance analysis using ROAS, MER, CPA, CVR, AOV, LTV, and contribution margin.
Diagnose funnel performance issues using analytics and customer behavior insights.
Define and manage break-even CPA and ROAS targets by store and product group.
Deliver weekly performance scorecards with clear insights, explanations, and next actions.
Build SOPs, documentation, and checklists to support future delegation.
Coordinate with CRO/Shopify implementers and creative resources to ship improvements weekly.

What We're Looking For

Hands-on operator who personally manages paid media and email execution.
Proven experience managing $100k+/month in ad spend (ideally $200k+) with documented performance results.
Strong understanding of direct-response marketing, human behavior, offers, hooks, and objections.
Advanced analytical skills with ability to identify what changed, why it changed, and what actions to take.
End-to-end ownership of measurement and tracking (UTMs, GA4 checks, pixels, CAPI, attribution).
Ability to manage toward break-even CPA, ROAS, and contribution margin, not vanity metrics.
Strong communication cadence with weekly planning, reporting, and prioritization.
Must have experience with Google Ads (Search, Shopping, Performance Max), Merchant Center, and basic product feed management.
Must have experience with YouTube Ads (creative strategy and measurement).
Must have experience with Meta Ads (testing, scaling, retargeting).
Must have experience with TikTok Ads (UGC-first testing; creator and Spark Ads workflows are a plus).
Must have experience with Klaviyo (campaigns, flows, segmentation).

Nice to Have

Experience scaling multi-store, international Shopify brands.
Basic creative skills (Canva or Photoshop) for rapid testing.
Affiliate program management.
Experience testing Pinterest, Reddit, or TV/OTT with strong measurement discipline.
Experience handling platform policy issues and account-risk scenarios.
