Sr. Growth Marketing Manager

Responsibilities

• 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.

Requirements

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

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.
