Role Description We're looking for a MarTech specialist with strong expertise in attribution, tracking, measurement and growth analytics across mobile apps and web products. The ideal candidate understands how app and web marketing ecosystems work: user acquisition, attribution, monetisation, tracking, and performance measurement. They should go beyond a standard Data Analyst in Martech depth and operational know-how, but do not need to build pipelines or infrastructure. This is the perfect opportunity for you if: - You’re looking for a place where you can work on a portfolio of apps, not just one. - You can go deeper into how growth actually works under the hood. - You’re surrounded by people who are just as curious (and stubborn) as you are. People who: - Care about why data doesn’t match. - Enjoy debating attribution logic. - Won’t look at you weird when you say “I checked the raw postbacks.” This role sits within MarTech, not within the Marketing / Paid UA team. You’ll work closely with UA folks but your focus is measurement, tracking, and infrastructure, not campaign execution. Long story short: making sure the data flows smoothly and is useful. 👉 You won’t just work on growth: you’ll help build the foundations that make it work.
