Role Overview 

We are seeking a fast-paced, client-facing MarTech Manager to lead marketing technology strategy, implementation, and troubleshooting across diverse LOBs for a major Omnicom client. Operating at the intersection of media, data science, and creative, you will audit the client stack, architect privacy-resilient tracking solutions, and unlock advanced personalization capabilities. You must be comfortable managing multiple LOB tracks for the client simultaneously, translating technical requirements for account teams, and pitching technical solutions to brand stakeholders. 

🎯 Agency Responsibilities 

• Multi-LOB CDP Management: Configure and manage Customer Data Platforms (CDPs) to unify first-party data, build high-value audience segments, and push unified cohorts directly to multi-channel execution platforms. 

• Agency DCO Scalability: Partner with creative and programmatic media teams to set up data feeds and decisioning engines for Dynamic Creative Optimization (DCO) campaigns, ensuring seamless asset mapping and real-time execution. 

• Signal Resiliency & Attribution: Implement Server-Side GTM and Conversions API (CAPI) protocols (Meta, Google, TikTok etc.) to recover lost signals, improve match rates, and optimize performance marketing attribution for agency accounts. 

• Client Tracking Stack Management: Technical audit of clients' new tracking infrastructure; design custom implementation blueprints covering Google Tag Manager (GTM), Google Analytics 4 (GA4), and customer data streams. 

🛠️ Technical Qualifications 

• CDP Operations: Experience managing multi-tenant or enterprise instances of CDPs like Adobe (AEP / RTCDP), Tealium, or ActionIQ to orchestrate cross-channel data. 

• CAPI Specialists: Hands-on experience deploying direct or gateway-based server-side marketing APIs to improve performance media attribution. 

• Agency Ad Tech Ecosystem: Expert-level knowledge of major ad servers and dynamic engines like Innovid, or Google Campaign Manager 360. 

• Enterprise GTM & GA4: Mastery of cross-domain tracking, custom data layers, server-side tagging architectures, and GA4 BigQuery configurations across diverse client tech stacks. 

💼 Agency Experience & Skills 

• Agency Background: 4+ years of experience working inside a digital media, programmatic, or full-service advertising agency environment. 

• Client-Facing Presence: Excellent executive presence and communication skills; capable of explaining complex data schemas, cookie deprecation, and tracking code to non-technical client and agency staekholders. 

• Velocity & Agility: Proven ability to manage deliverables across 4 to 8 active client engagements concurrently under tight media launch deadlines.
