Team
Join Cortex, a small, fast-moving studio building smart mobile puzzle games — The Almanac, a daily ritual for tens of thousands of players, and our new titles like Shikaku. We’re a lean, growth-driven team backed by Voodoo. You’ll sit at the heart of how we find and convert new players.
Role
As Cortex’s Growth Manager, you’ll own the creative engine behind our user acquisition. Your job is to produce a high volume of ad creatives with AI tools, test them fast, and find what makes players click and install. You’ll start on creative production and ASO, and progressively grow into monitoring and steering our UA campaigns day-to-day. This is a junior role, ideal for a first or second professional experience — we hire on your creative output and your energy, not your CV.
Responsibilities
Produce a high volume of ad creatives (video, static, playable concepts) using AI tools like Scenario, Midjourney, Runway and CapCut
Test creatives, read the results, and iterate fast to bring the CPI down
Own ASO across the App Store: keywords, screenshots, and continuous iteration
Watch the market and competitors to feed fresh creative angles
Support and progressively take ownership of daily UA monitoring (AppLovin, Meta)
Work hand-in-hand with the founder, and level up on UA economics through an onboarding with Voodoo’s growth team
Profile
Gen Z, marketing brain paired with creative hands
Already creating on your own — a faceless page, UGC, AI experiments. You bring a portfolio, not a diploma
Fluent with AI creative tools, or the kind of person who learns a new tool in an afternoon
Analytical curiosity: you want to understand why a creative converts
Huge energy and ownership, comfortable shipping 10 rough creatives to find the 1 that works
Video editing is a strong plus
Fluent English
Benefits: Competitive salary, performance bonus, and other benefits according to the country you reside in.
