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

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.

Our Values in Action

• See it, fix it Broken tracking someone else’s problem

• Ownership You bring solutions, not just problems

• • Work on a portfolio of apps, not just one
  • Be the bridge between UA and Tech (MarTech layer)
  • Own and shape measurement & attribution foundations
  • Join a team that:
  • • Checks raw data
    • Questions attribution
    • Actually cares about how things work
• And yes — this is a place where:
• • “data doesn’t match” is not accepted
  • “it’s probably SKAN” is not a final answer
  • And going one layer deeper is just part of the job
