From the employer

Marketing Technology Specialist

Driving the next generation of wealth.

Digital assets are redefining how wealth is created, used, and transferred. Since 2018 at Nexo, we have been building the future model of financial wealth - dynamic, accessible, and designed for a new generation of forward-thinking investors.

But technology alone doesn’t drive progress. People do.

We are a team of builders, strategists, analysts, creatives, and operators united by a shared mindset: advancement. We move fast, think long term, and take ownership. We challenge ideas, not people. We value clarity over noise and impact over optics.

What makes Nexo different?

We shape industry trends. We rethink how wealth works and build solutions that reflect that belief.

That requires a certain kind of person.

You will thrive here when you think independently and act decisively, take ownership without waiting for permission, and care deeply about quality, long-term value, and disciplined execution. The people who succeed at Nexo bring analytical depth, sound judgment, and resilience - but also curiosity and the drive to keep improving.

This is an environment for people who want to lead, create, and elevate what already exists. If building what’s next excites you, you’ll feel at home at Nexo.

Your role:

Implement and test end-to-end event tracking across web and mobile in GTM, Segment, Adjust, and GA4; own the event schema and the data Layer specification.
Resolve measurement discrepancies with Engineering: platform against platform, app against web, expected against what actually fired, and validate attribution.
Build and maintain customer data flows in Segment CDP: sources, destinations, identity resolution, and the governance that stops the schema from drifting.
Script API jobs and maintain ETL tasks in Python or JavaScript so reporting, audience syncs, and QA checks run without manual effort.
Keep consent and privacy watertight: CMP/OneTrust mappings, tag gating by jurisdiction, and PII review before anything ships.
Peer-review new configurations, and document the stack so it is not held in one person’s head.
Scope requirements with Marketing, BI, and Engineering, prioritize by business impact, and deliver on schedule.
Track and analyze mobile performance through Adjust, and turn it into decisions on spend and creativity.

What makes you stand out:

2–5 years implementing marketing or product measurement, in-house or agency-side (tech, fintech, or crypto a plus).
Hands-on with a tag manager and an analytics platform - GTM and GA4, or equivalents such as Tealium, Piwik PRO, Amplitude, or Mixpanel. You have built and debugged a dataLayer, not only read the reports.
Working knowledge of a CDP (Segment, RudderStack, mParticle, Tealium) and of a mobile measurement partner (Adjust, AppsFlyer, Branch, or similar).
Scripting in Python or JavaScript for automation and data transformation, plus SQL for data pulls, QA, and troubleshooting ETL tasks.
Consent and privacy in practice: a CMP such as OneTrust, and GDPR/CCPA obligations.
Professional fluency in English (our working language), and the ability to explain technical requirements and project status to people who do not work in martech.
Server-side tagging, server-side GTM, or Segment Functions.
App measurement specifics: SKAdNetwork, deep links, deferred deep linking.
Dashboards in Looker Studio or Tableau.
Certification in an analytics, CDP, or marketing automation platform.
Prior experience in crypto, Web3, or regulated financial products.

Nexo benefits:
