We are looking for a Senior MarTech Specialist with strong expertise in web tracking projects, ideally with experience in companies where subscriptions are the main revenue stream. 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. Degrees are nice, but we care about your skills, curiosity, and hands‑on experience.

Requirements
*
* Deep expertise in Google Tag Manager (client‑side + server‑side) – proven experience implementing and maintaining S2S GTM setups.
* Experience with web projects, ideally subscription‑based businesses.
* Hands‑on experience with online payments (Stripe, card gateways) and the ability to capture and process payment data for analytics and attribution.
* Experience with GA4 and Amplitude. Knowledge of Adobe Analytics (or similar enterprise platforms) is a plus – GTM expertise is mandatory.
* Strong background in web tagging and tracking (events, funnels, data layers).
* Solid understanding of how Ad Networks work – e.g. the difference between Campaign / Ad Group / Ad, how CAPI or parameter‑based tracking works, and how UA teams rely on these setups.
* Solid understanding of Technical SEO fundamentals (indexation, sitemaps, canonicals, hreflangs, Core Web Vitals).
* Experience working with SEO teams.
* Awareness of AEO – understanding how search and discovery through LLMs (ChatGPT, Perplexity, etc.) works, so you can evaluate the value of these appearances and attribute them.
* Experience with CMPs / consent management tools (e.g. Didomi, OneTrust, Usercentrics, or similar). Hands‑on work with Legal teams, verifying implementations, and ensuring signals fire correctly.
* Practical experience with cloud systems (ideally GCP: BigQuery, Cloud Functions, Pub/Sub, APIs).
* SQL proficiency to query and consume data in a Data Warehouse (e.g. BigQuery, Databricks).
* Fluent English (written & spoken).
Nice‑to‑have
*
* Experience with other tagging systems (Tealium, Adobe Launch, etc.).
* Experience with Customer Data Platforms (CDPs) such as Segment, mParticle, Rudderstack or Composable CDPs like Census, Hightouch.
* Experience with dashboards and BI tools – e.g. Looker Studio, Tableau, Power BI – to help Paid UA teams analyze test results.
* Experience with CRMs and marketing automation platforms – e.g. Braze, Iterable, OneSignal, Hubspot, Brevo, ActiveCampaign.
* App‑side exposure: understanding of Paid UA for apps including SKAN and how it impacts iOS campaigns; basic knowledge of how SDKs in mobile apps work, and how to reduce dependencies on app releases.
* Experience with server‑to‑server integrations beyond GTM (direct API setups, custom pipelines).
Benefits
*
* Growth and career development – flexible career path with personalized internal training and annual budget for external learning.
* Work‑life balance – flexible schedule with flextime (7 – 9:30 a.m. start, 3:30 – 6 p.m. end) and option of full remote or Barcelona office; free Friday afternoons with a 7‑hour workday, plus a 35‑hour workweek in July and August.
