Job Description

We are looking for a MarTech Specialist with strong expertise in web tracking projects, ideally with experience in companies with subscriptions models. This is not a “ticket executor” role. We want someone who owns the tech side of web tracking, challenges assumptions, and builds scalable, future-proof solutions.

Job Responsibility

  • Own the technical implementation and maintenance of web tracking (client-side and server-side)
  • Lead Google Tag Manager setups (including S2S GTM) and ensure accurate data capture for analytics and attribution
  • Work on web projects, ideally for subscription-based businesses
  • Implement and manage online payments data capture (e.g., Stripe, card gateways)
  • Use GA4 and Amplitude
  • Maintain robust tagging and tracking (events, funnels, data layers)
  • Collaborate with SEO teams on landing pages, organic funnels, and Google Search Console insights
  • Engage with CMPs/consent management tools and coordinate with Legal teams to ensure proper signal firing and compliance
  • Leverage cloud systems (ideally GCP) and SQL to query data in a Data Warehouse
  • Coordinate with App MarTech where relevant

Requirements

  • Deep experience working on web products in production
  • Deep understanding of attribution across modern tracking environments
  • Solid understanding of how Ad Networks work
  • Experience working with architectures where tools like Google Tag Gateway (GTG) or equivalent network-side signal routing solutions play a key role
  • Experience designing, implementing, and optimizing server-to-server (S2S) conversion and event tracking setups across Ad Networks
  • Understand how hashing, normalization, and formatting of user identifiers directly impact match rates
  • Hands-on experience with online payments (Stripe, card gateways)
  • Experience with GA4 and Amplitude
  • Experience with CMPs / consent management tools (e.g., Didomi, OneTrust, Usercentrics)
  • Practical experience with cloud systems (ideally GCP: BigQuery, Cloud Functions, Pub/Sub, APIs)
  • SQL proficiency
  • Fluent English (written & spoken)

Nice to have

  • Python (or other scripting languages) for automation
  • Data Engineering / Analytics Engineering exposure (e.g., Airbyte, dbt, Dataform)
  • Experience with Affiliation platforms (e.g., Impact, Rakuten, Awin)
  • Solid understanding of Technical SEO fundamentals
  • Experience with other TMS systems (Tealium, Adobe Launch, etc.)
  • Experience with Customer Data Platforms (CDPs)
  • Experience with dashboards and BI tools
  • Experience with CRMs and marketing automation platforms
  • Awareness of AEO (Answer Engine Optimization)

What we offer

  • Real ownership of projects
  • Room to grow
  • Future opportunities
  • A company where your voice matters
