About the roleWe're looking for a Senior User Acquisition Manager to own Google Ads performance across our product portfolio. You'll manage large-scale Search campaign structures spanning dozens of countries and languages, drive profitable scaling through rigorous CPA/ROI discipline, and partner closely with data and creative teams to keep quality high as we grow. This is a hands-on, high-ownership role — you'll be in the account daily, not just reviewing dashboards. We offer a genuinely competitive salary for the right person.
Key ResponsibilitiesOwn the Google UA channel end-to-end — full accountability for CPA/ROI and budget across every market. Prove the model works, and we'll hand you an unlimited budget to scale it further.
Scale into new markets methodically: keyword research, native-language ad copy sign-off, compliance review, and QA before every launch — never launching on guesswork.
Make data-driven CPA/ROI calls — set and defend target CPAs per country using cohort ROI data (D7/LTV), not vanity metrics; know when a market's ROI doesn't clear the bar and say so.
Run the optimization loop: search-term mining, negative-keyword hygiene, bid adjustments, Quality Score / Ad Strength improvement, budget reallocation toward what's working.
Enforce compliance and brand safety at scale — policy-sensitive verticals require zero tolerance for banned claims, misleading copy, or trademark issues, across every language you launch in.
Partner cross-functionally with analytics/BI (Omni/BigQuery), creative, and product to align acquisition targets with unit economics and product changes.
4+ years running Google Ads at meaningful scale (6-figure+ spend), ideally in consumer subscription, D2C, or performance-marketing-heavy environments.
Deep hands-on fluency with the Google Ads platform and API/scripts (bulk campaign builds, bidding strategies, RSA optimization, audience layering) — not just the UI.
Strong quantitative decision-making: comfortable with CPA/ROAS/LTV cohort math, SQL or BigQuery a strong plus.
Proven experience scaling into new international markets — geo/language expansion, working with native-language reviewers, adapting to local compliance nuances.
Sharp eye for ad policy and compliance risk — you catch a risky claim before Google does.
High attention to detail and comfort owning structure at scale (dozens of campaigns, hundreds of ad groups) without losing the thread.
Excellent written English; comfortable working with global, async teams.
Hands-on experience with Microsoft/Bing Ads and/or Meta Ads alongside Google — a strong plus.
Familiarity with BI tools (Omni, Looker, Tableau) for cohort/ROI analysis.
Skills with AI-models (Claude ,OpenAI, etc ..)
Google Ads certifications.
