Vendors / Purposes
We’re looking for a hands‑on Mid‑Level MarTech Specialist with solid expertise in web tracking, attribution, acquisition ecosystems, and subscription‑based businesses.
This is not a “ticket executor” role.
We want someone who already understands how modern web acquisition works — from attribution models and browser limitations to GTM server‑side setups, consent frameworks, SEO traffic, and raw Ad Network data.
You’ll work closely with Paid UA, SEO, Product, Data, and Engineering teams to build scalable tracking architectures that survive real‑world conditions: browser restrictions, consent limitations, signal loss, broken payment flows, inconsistent attribution, and all the other fun things the internet throws at us.
What We Care About
Curiosity
Problem‑solving
Ownership
Technical understanding
Your ability to make things work in production

Help improve conversion visibility and signal quality across Ad Networks.
Collaborate with Paid UA teams to ensure campaigns receive high‑quality conversion data.
Work with SEO teams to understand organic funnels, landing page behavior and traffic quality.
Investigate discrepancies between platforms (GA4, Amplitude, Meta Ads, Google Ads, internal BI, etc.).
Validate implementations directly in DevTools, network requests, payloads, cookies, APIs and browser storage.
Support consent‑aware tracking implementations alongside Legal and Product teams.
Use raw data from Ad Networks, analytics tools, and cloud systems to understand attribution and performance.
Help design scalable event taxonomies and tracking architectures.
Debug problems end‑to‑end instead of escalating them endlessly.

How We Think & Work
We’d love you to see yourself in these principles, because they’re not just words — they show up in our daily work.
Level up
We grow, and we make our teammates grow. If you discover a better way to structure tracking or a smarter SQL approach, you share it. If Paid UA asks for a new event, you ask “why?” before blindly implementing it.
See it, fix it
We don’t let problems rot.
If conversion tracking breaks on Friday, we don’t wait until Monday to investigate. If GA4 and Amplitude disagree, you dig until you understand why.
Always ahead
Browser updates, cookie changes, privacy frameworks, new APIs, attribution shifts… we stay ahead. You’re the kind of person who reads changelogs before production breaks.
Now means now
If something can be solved today, we solve it today. We value ownership and execution over endless process.
Team spirit
We collaborate.
You help SEO debug a landing page issue. You help Paid UA understand why Meta conversions dropped. And sometimes you also share memes about Google making everyone’s lives harder.
Hands‑on
You don’t wait for perfect conditions. Need test data? You create a test flow. Need to validate attribution? You reproduce the journey yourself.
Translator mindset
You can explain technical concepts to marketers. And you can explain acquisition realities to engineers. Both sides leave the conversation understanding each other better.
