[Hiring] Sr. Growth Marketing Manager @iHerb, LLC

Role Description

The Sr. Growth Marketing Manager owns paid growth, end to end, for an assigned country or cluster of countries, and is accountable for the new-customer and revenue outcomes those markets deliver. This is a senior individual-contributor role on the Global Growth Marketing team: this role carries the P&L-level thinking of a market lead and the hands-on platform depth of a channel expert, without people-management responsibility.

• Own performance channels end to end for your assigned country(ies).
• Own the paid media budget, forecast and monthly pacing for your markets across:
  • Google (Search, Shopping, Performance Max, Demand Gen, YouTube)
  • Meta (Advantage+ Shopping and Sales)
  • TikTok (Smart+)
  • ChatGPT Ads
  • Apple Search Ads
  • Local platforms where they matter (e.g., Naver, Yahoo! Japan, Yandex, Kakao)
• Set the channel and campaign structure, bidding strategy, audience and feed strategy, and launch cadence; run weekly optimization and monthly reallocation against combined-return targets.
• Hit new-customer, revenue, CAC and return targets for your markets.
• Translate market context into media decisions: local competitors, promotional calendars, payment and delivery dynamics, category seasonality and regulatory constraints on supplement and wellness advertising.
• Partner with regional marketing, merchandising, CRM, SEO and the retail media (RAS) team.
• Be the platform expert: Stay ahead of the roadmaps of Google, Meta, TikTok, ChatGPT ads and other paid channels.
• Own signal quality: ensure Conversions API, enhanced conversions, server-side tagging, offline and value-based conversion feeds give the platforms the right optimization target.
• Design first-party data activation with the CRM and data teams.
• Build direct working relationships with platform account teams.
• Use media mix modelling (MMM) and incrementality testing (geo-lift, conversion-lift, holdouts) alongside platform attribution to set budgets by channel and market.
• Define and defend the KPI framework for your markets.
• Lead performance creative strategy: write briefs grounded in audience and platform insight.
• Use AI tooling for analysis, forecasting, creative iteration and campaign operations.
• Produce the weekly and monthly performance narrative for your markets.

Qualifications

• Hands-on, current expertise in Google Ads and Meta Ads at scale.
• Demonstrated use of media mix modelling and incrementality testing.
• Strong analytical ability: fluent in SQL or comfortable working in a lakehouse / BI environment.
• Proven performance creative judgment.
• Clear written and verbal communication with senior stakeholders.
• Operates independently, sets own priorities, and delivers outcomes.

Requirements

• Generally requires 10+ years in performance or growth marketing.
• At least 3 years directly owning paid media budgets and outcomes for an e-commerce, marketplace or DTC business.
• Multi-country or cross-market experience is preferred.

Education Requirements

• A bachelor’s degree in marketing, advertising, statistics, or other related field.
