About The Position

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

Requirements

• Mastery of cross-domain tracking, custom data layers, server-side tagging architectures, and GA4 BigQuery configurations across diverse client tech stacks.
• Hands-on experience deploying direct or gateway-based server-side marketing APIs to improve performance media attribution.
• Experience managing multi-tenant or enterprise instances of tools like Segment, Tealium, or ActionIQ to orchestrate cross-channel data.
• Expert-level knowledge of major ad servers and dynamic engines like Innovid, Flashtalking, or Google Campaign Manager 360.
• 4+ years of experience working inside a digital media, programmatic, or full-service advertising agency environment.
• Excellent executive presence and communication skills; capable of explaining complex data schemas, cookie deprecation, and tracking code to non-technical client brand managers.
• Proven ability to manage deliverables across 4 to 8 active client accounts concurrently under tight media launch deadlines.

Responsibilities

• Technical audit of new clients' tracking infrastructure; design custom implementation blueprints covering Google Tag Manager (GTM), Google Analytics 4 (GA4), and customer data streams.
• Implement Server-Side GTM and Conversions API (CAPI) protocols (Meta, Google, TikTok) to recover lost signals, improve match rates, and optimize performance marketing attribution for agency accounts.
• 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.
• 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.
• Collaborate with account directors to write technical Statements of Work (SOWs), estimate implementation hours, and act as the subject matter expert during new business pitches.
