Get to Know Darwoft
At Darwoftgic thinking, creative execution, and data-driven marketing to help universities and organizations achieve measurable growth.
Company Overview:
Our client is a fast-growing performance marketing agency specializing in mission-driven organizations across higher education and nonprofit sectors.
Since launching in ****, the agency has built a strong reputation for combining strategic thinking, creative execution, and data-driven marketing to help universities and organizations achieve measurable growth.
Your Role:
The Tracking Specialist is a key member of the agency's Data and Analytics team, owning the web analytics and pixel deployment architecture that everything downstream depends on.
You'll implement tracking via Google Tag Manager, troubleshoot setup issues across every paid ad platform the agency runs, and make sure data collection from client websites is airtight, from the first click through to CRM entry.
Reporting to the Data and Analytics Manager,



you're joining at a pivotal moment — the agency is scaling its roster of education and nonprofit partners, and this role is instrumental in evolving the tracking workflow that keeps every campaign measurable and every report trustworthy.
You'll:
Own tag management & deployment — deploy, configure, and maintain pixels, tags, and scripts in Google Tag Manager (native templates and Custom HTML); build and maintain data layers with the Web Services team; manage GTM container structure, triggers, and variables across a multi-client environment; implement server-side tagging where it improves measurement accuracy and durability
Own conversion tracking & platform integration — connect website activity to paid ad platforms (Meta, Google Ads, TikTok, LinkedIn, Snapchat) using both browser pixels and Conversion APIs (CAPI); configure standard and custom events (leads, applications, inquiries) for accurate reporting and platform optimization; configure and maintain event tracking and key events in GA4 from ad click through form submission and CRM entry; partner with Paid Media and Web Services so every campaign and landing page launches with tracking implemented and verified
Own QA, debugging & data integrity — audit and debug broken tags, dropped events, and data discrepancies across client websites; troubleshoot mismatches between ad platforms, GA4, and CRM to root cause; run routine tag health audits across the portfolio; verify events in platform Events Managers and GA4 DebugView before any campaign goes live
Own data privacy compliance — manage cookie consent banners and consent mode configuration across client sites; keep tracking implementations aligned with GDPR, CCPA, and other privacy regulations; monitor platform and browser changes that affect tracking durability and recommend adjustments
Support documentation & cross-team enablement — maintain tagging plans, naming conventions, and QA checklists; translate business requirements from account and client teams into functional tracking solutions; document technical setups so internal teams can interpret and rely on the data
You Bring:
3+ years of hands‐on tracking or web analytics experience in a marketing or agency environment
Intermediate experience with GTM containers, trigger and variable creation, data layer implementation, and server-side tagging
Practical experience planning, deploying, and troubleshooting conversion tracking across major ad platforms, with working knowledge of pixel and Conversion API (CAPI) configuration for Meta, Google Ads, TikTok, and LinkedIn

including event configuration, key events, and DebugView
Comfort with HTML, CSS selectors, and basic JavaScript for tag troubleshooting and custom script implementation, and skilled use of GTM Preview mode and browser developer tools (inspect element, network tab)
Understanding of data privacy requirements (GDPR, CCPA) and consent management platforms, and of how tracking decisions affect Paid Media performance KPIs
An analytical, solution-driven mindset with a growth orientation, and strong communication skb Copilot, coding agents, AI-assisted specifications, or similar tooling.
