Job Summary: 

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.

iHerb sells to customers in 180+ countries, so the markets you own are real businesses with their own competitive dynamics, seasonality, platform mix and customer economics. You plan how media is allocated across Google, Meta, TikTok, Apple Search Ads, affiliates and emerging platforms in your markets; you build the measurement that proves it worked; and you shape the creative strategy that makes the algorithms perform.

The role sits at the intersection of three disciplines we expect you to be fluent in: performance channel management (budgets, bidding, structure, pacing), paid platform expertise (AI-driven campaign types, signal quality, first-party data activation) and performance marketing domain knowledge (media mix modelling, incrementality testing, KPI design and performance creative).

Job Expectations:

• 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, and 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. You are the single point of accountability for paid performance in those countries and the first person leadership asks when the numbers move.
• 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 so that paid acquisition, on-site and lifecycle efforts compound rather than compete.

Be the platform expert:

• Stay ahead of the roadmaps of Google, Meta, TikTok, ChatGPT ads and other paid channels; run structured alphas and betas; and make the call on when a new AI-driven campaign type is ready for scale in your markets.
• Own signal quality: ensure Conversions API, enhanced conversions, server-side tagging, offline and value-based conversion feeds give the platforms the right optimization target, including LTV- and margin-weighted values.
• Design first-party data activation with the CRM and data teams: customer-list audiences, exclusions, predictive LTV segments and lookalike or Advantage+ audience strategies.
• Build direct working relationships with platform account teams and use them to secure betas, incentives and support.

Performance marketing domain depth:

• Use media mix modelling (MMM) and incrementality testing (geo-lift, conversion-lift, holdouts) alongside platform attribution to set budgets by channel and market. Design and run the tests; interpret them; change the plan based on the result.
• Define and defend the KPI framework for your markets: new-customer CAC, blended and incremental return, contribution margin after discount and media, payback, and cohort LTV. Reconcile platform-reported, modelled and finance-reported views.
• Lead performance creative strategy: write briefs grounded in audience and platform insight, run hook/body/CTA element-level testing, manage a creative testing backlog with the creative and AI-production teams, and track creative fatigue and refresh cadence.
• Use AI tooling for analysis, forecasting, creative iteration and campaign operations, and set the example for how a modern performance marketer works.
• Produce the weekly and monthly performance narrative for your markets: what happened, why, what you are changing, what you need. Present to senior leadership with clarity and a point of view.

Tools and resources you'll work with

• Data and analytics: Enterprise lakehouse (Databricks) with natural-language querying, daily spend pacing and channel dashboards, cohort and LTV models, and a combined media-plus-discount return model across our budgeted markets
• Measurement: In-house media mix modelling, geo and conversion-lift incrementality testing, server-side tagging and Conversions API integrations with Google, Meta and TikTok
• Platforms: Direct account teams at Google, Meta, TikTok and Apple; access to alphas and betas; AI-driven campaign types live across markets
• Creative: In-house creative and AI-assisted production, a structured creative testing process, and element-level creative performance reporting
• AI tooling: Enterprise access to leading AI assistants and agents connected to our ad platforms, data warehouse and reporting, used daily for analysis, forecasting, creative iteration and campaign operations
• Scale: 180+ countries, 46 site languages, 85 currencies and a customer base of 16M+ active customers, with marketing teams on the ground in APAC, MENA, Europe and the Americas
• The duties and responsibilities described above may provide only a partial description of this position. This is not an exhaustive list of all aspects of the job.  Other duties and responsibilities not outlined in this document may be added as necessary or desirable, with or without notice.

Knowledge, Skills and Abilities:

Required:  

• Hands-on, current expertise in Google Ads and Meta Ads at scale, including Performance Max, Demand Gen, Advantage+ Shopping, Conversions API and value-based bidding. Working knowledge of TikTok Ads, ChatGPT ads and other paid ads channels.
• Demonstrated use of media mix modelling and incrementality testing to change budget decisions, not just to report on them. You can explain the limits of each method and when to trust which number.
• Strong analytical ability: fluent in SQL or comfortable working in a lakehouse / BI environment (e.g., Databricks, Looker, Tableau), able to build your own analyses rather than wait for a request to be fulfilled.
• Proven performance creative judgment: you have written briefs, run structured creative tests and can show how creative changed your results.
• Clear written and verbal communication with senior stakeholders; comfortable owning a number in a room of executives.
• Operates independently, sets own priorities, and delivers outcomes without a team reporting to you.

Preferred

• Experience in health, wellness, supplements, beauty or regulated consumer categories.
• Experience with retail media networks, affiliate and partnership marketing, or app marketing (ASO, MMP data such as AppsFlyer or Adjust).
• Experience in APAC, MENA or European markets and with local platforms (Naver, Yahoo! Japan, Kakao, Yandex, LINE).
• Familiarity with open-source or vendor MMM frameworks (Measured, Meridian, Robyn, PyMC-Marketing, or commercial equivalents) and with geo-experiment design.
• Hands-on use of generative AI tools for analysis, creative production and campaign operations.
• Additional language skills relevant to the assigned markets.

Experience Requirements:

Generally requires 10+ years in performance or growth marketing with 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.
