Web: GTM / tagging, pixels, GA4 or equivalent, SEM / paid social platforms, landing pages

We're looking for a

MarTech specialist

with strong expertise in attribution, tracking, measurement and growth analytics across mobile apps and web products.

The adecuado 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

Care about why data doesn’t match

Enjoy debating attribution logic

And 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.

What You’ll Do

Own and improve attribution & tracking across apps and web

Maintain and improve measurement architecture for mobile (MMP-led) and web (tagging / pixels / data layer-led) setups

Ensure app and web data connect cleanly where funnels cross channels (W2A, web-to-app, cross-device journeys)

Debug issues across the full funnel

Apps: Click Install Event Revenue

Web: Visit Landing Tag fire Conversion Revenue / lead / signup

Trace breaks across sources and teams, not just in one tool

Ensure clean and consistent data across

Mobile: MMP (ideally AppsFlyer), ad networks, product analytics (e.g. Amplitude), monetisation (RevenueCat / Adapty)

Web: GTM / tagging, pi
