- 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: G
