MarTech Specialist (Apps)

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

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, pixels, GA4 or equivalent, SEM / paid social platforms, landing pages

Shared layer: event definitions, naming, mapping logic, and reporting inputs used by UA and growth

Design and validate:

Apps: postbacks (S2S), event mappings, attribution logic & windows

Web: conversion events, tag configuration, parameter capture, campaign tracking consistency

Work on Web2App (W2A) flows:

Capture parameters on landing pages

Ensure correct stitching into app attribution

Collaborate closely with UA, Product, and Engineering:

Validate SDK implementations

Ensure events are triggered correctly

Raise and propose fixes when something breaks

Work with subscription & monetization data:

Integrate platforms like RevenueCat / Adapty

Handle webhook / S2S data flows into the warehouse

Support UA Managers by ensuring:

The data they optimize on is actually reliable

Campaign signals (events, revenue) are correctly implemented

Requirements

Core requirements:

Fluent English skills: Clear communication with UA, MarTech and Data teams is essential. We're not expecting you to fully understand Peaky Blinders without subtitles - but you should feel confortable communicating in your day-to-day work.

Martech & Marketing Knowledge (priority)

Must understand growth and measurement across mobile and web:

Mobile

Attribution / MMP: AppsFlyer (preferred), Adjust, Singular

Monetisation: RevenueCat, Adapty, Superwall

Product analytics: Amplitude

Web

Web analytics & tagging: GTM, pixels, event/data layer setup

Web acquisition: SEM, paid social, landing pages, conversion tracking

Cross-channel measurement: how web and app funnels connect (W2A, web-to-app, etc.)

Shared knowledge:

User acquisition (UA)

Ad networks and campaign performance measurement

Tracking and event instrumentation

Funnel analysis and cohort thinking (install/visit trial payment recurrence)

Data quality: spotting gaps, discrepancies, and broken tracking

Technical / Analytics Requirements:

SQL and comfort working with marketing data

Ability to clean, validate, and analyse tracking data across sources

Understanding of APIs and event-based integrations (supporting automations, not building them)

Comfortable collaborating with technical teams on data issues, pipelines, and integrations

Example of the level expected:

Investigating discrepancies between MMP, product analytics, and monetisation data

Auditing tracking setup (app or web) and defining what’s missing or broken

Building analyses around UA performance, payment cohorts, or conversion funnels

Supporting growth/UA teams with clear, actionable measurement - not owning infra

Nice to Have:

GCP familiarity: BigQuery, Cloud Functions, cloud-based event processing

Experience with conversion APIs (Google, Meta, TikTok, etc.)

SKAN / iOS privacy and attribution changes understanding

AdMob and hybrid monetisation models understanding

Exposure to internal martech platforms or conversion routing tools

Analytics Engineering background

Mindset: What Makes You a Great Fit

You’re a doer

If you don’t know something you figure it out:

Tutorials

Forums

Deep dives

Tools like Perplexity AI

You:

Don’t trust data blindly

Enjoy debugging

Like understanding how things actually work

You’re comfortable:

Exploring repos

Understanding SDK implementations

Proposing (or even making) small fixes when needed

You don’t just find problems - you fix them.
