User Acquisition Manager - Mobile

Guardio is on a mission to redefine consumer cybersecurity for the modern internet.



We operate at consumer scale, protecting millions of people every day across devices, accounts, and digital touchpoints. In a world where phishing, fraud, and AI-powered scams evolve overnight, Guardio stays ahead of the curve.

We move fast, think deeply, and build with purpose. Our culture is rooted in transparency, feedback, and collaboration along with shared wins, team dinners, company trips, and good times.

We’re a team of 100+ makers, doers, and boundary-breakers. If you’re ready to tackle meaningful challenges, grow at lightning speed, and help shape the next frontier of online safety, you belong here.

So, what's the job?



We're building Guardio's direct-to-app acquisition engine from the ground up. This role is about finding, building, and scaling the right mobile-first channels. You'll work closely with Data and Creative, and you'll have real ownership over budget, account structure, creative and channel strategy.

You will:

• Find, test, and scale mobile-first channels - Google App Campaigns (UAC), Meta, TikTok, Apple Search Ads, mobile DSPs.
• Own account structure, budget allocation, and bidding across everything you run.
• Judge channels on payback and incrementality.
• Work with MMP data. Know where it's delayed or unreliable, and when to run a geo holdout instead.
• Own creative strategy on your channels - brief Creative on what's working and keep a steady testing cadence.
• Move fast when platforms change the rules.
  
  

• 3+ years running mobile app user acquisition, in a company where installs had to turn into revenue.
• Proven, hands-on expertise in managing at least one major mobile acquisition channel, such as Google App Campaigns (UAC), Apple Search Ads (ASA), Meta D2A, TikTok D2A, or Applovin D2A.
• Comfortable building from zero: no baseline, no playbook, incomplete data.
• Proficient in working with Mobile Measurement Partners (MMPs) such as AppsFlyer, Adjust, Singular, and Branch.
• Strong analytical instincts and comfort with large data sets.
• Experience with international campaigns, primarily US and English-speaking tier-1 markets.
• Fluent English - written and verbal.
