Mobile App Growth Expert — User Acquisition & Hybrid Monetization

Location: Fully Remote

\Employment Type: Contract / Fractional (30 hours per month)

Seniority Level: Senior / Lead

Industry: Mobile Apps — Utility

Compensation:

This is a performance-aligned fractional engagement structured in two components:

• Monthly Retainer: $4,000 – $6,000 USD, covering 15 hours per month of strategic work. Final rate based on experience and scope.
• Performance Share: 20% of incremental net profit above an agreed baseline, paid quarterly. Baseline is set at the start of the engagement and reset every 12 months.

This structure is designed to attract operators who want real upside tied directly to the results they create. If you grow the business, you share meaningfully in the growth.

About Us 

We are an established mobile app studio developing and marketing a portfolio of utility apps. Our 

business model is hybrid: ads are the primary revenue driver, supported by weekly, monthly, and 

annual subscriptions plus one-time IAP offers (remove-ads, pro upgrades, unlocks). We're looking for 

a senior operator to take strategic ownership of the full growth engine on a fractional basis. 

This is a senior role. We are not hiring junior marketers, generalists, or candidates looking to learn 

on the job. Our team handles day-to-day execution; we need someone who can set the strategy 

across all three revenue levers, tune the numbers, and compound results quarter on quarter.

Scope

This role focuses on two utility apps from our portfolio with proven retention profiles, but that have not yet been scaled through paid acquisition:

Combined planned ad spend will ramp from initial testing (~$10–15k/month combined) to approximately $100,000 USD per month once unit economics are validated. We have additional apps in our portfolio; those are out of scope for this engagement. We've deliberately concentrated effort on our highest-potential apps rather than spreading across the full portfolio. 

The Role 

You will own all three revenue levers together: paid user acquisition, ad monetization, and 

subscription/IAP optimization. In an ad-first utility app, these are one optimization problem; the 

people who scale these businesses best are the ones who see it that way, not as three separate 

specialties. 

Key Responsibilities 

• Design and execute the scale-up plan for the three in-scope apps, moving from testing budgets to sustained $100k/month combined spend as unit economics are proven 
• Set UA strategy across Meta and Google Ads (UAC), including bidding, creative testing frameworks, and scaling decisions 
• Own the ad monetization stack end-to-end: mediation setup, waterfall and bidding configuration, eCPM optimization, and ad placement strategy 
• Optimize subscription performance: paywall design and placement, weekly vs monthly vs annual pricing, trial-to-paid conversion, price localization across geos, and churn management 
• Optimize the IAP layer: remove-ads and pro-upgrade offers, pricing, and A/B testing of in-app offers to improve ARPDAU without cannibalizing ad revenue 
• Manage and optimize LTV/CAC, ROAS, and payback windows — with LTV correctly blending ad revenue, subscription revenue, and IAP revenue 
• Work alongside our product and engineering team on SDK integrations, ad UX, paywall UX, and A/B tests affecting monetization 
• Report directly to the founders on growth performance, unit economics, and strategic direction 

Required Experience 

• Minimum 5 years in mobile growth, with demonstrable hands-on experience across UA, ad monetization, and subscription/IAP optimization 
• Proven track record scaling hybrid-monetized utility or casual-gaming apps to meaningful revenue 
• Deep, hands-on expertise with at least one major mediation platform: AppLovin MAX, IronSource LevelPlay, Google AdMob, or equivalent 
• Fluent in paid acquisition across at least two platforms: Meta, Google UAC, TikTok, Mintegral 
• Practical experience with subscription paywalls (weekly/monthly/annual pricing, trial mechanics, price localization) and IAP A/B testing in ad-first apps 
• Strong analytical skills — fluent in cohort analysis, blended LTV modeling, and attribution (AppsFlyer, Adjust, or similar) 
• Experience managing monthly ad spend of at least six figures USD • Professional English, written and spoken.  

Preferred Experience 

• Experience scaling utility apps from early-stage to $50k+/month profitable ad spend 
• RevenueCat, Adapty, Qonversion, or similar subscription infrastructure exposure 
• Familiarity with incrementality testing and media mix modeling 
• Prior fractional or advisory experience with multiple app studios 

Who This Role Is Not For 

• Junior or mid-level marketers seeking a step up 
• Agency account managers without hands-on in-house experience 
• Specialists in only one discipline (UA, ad mon, or subscription) looking to learn the others on the job 
• Pure subscription-app growth leads; our model is ad-first with supporting subscription and IAP layers. If you have never optimized a mediation waterfall, this is not the role for you 

What We Offer 

• Full strategic ownership of the growth function with direct access to founders 
• Fully remote, paid in USD 
• Fast decisions, no bureaucracy, and a team that actually ships 
• Meaningful performance upside
