We're full-service, with people and AI agents working side by side, all aligned to one thing: maximizing our clients' revenue through a genuinely scientific approach to media. If you want to help play your part in achieving this for the world's biggest brands in an environment that will support and challenge you in equal measure, this is where you do it. So you're interested in joining Brainlabs as a Senior Digital Analytics Specialist? Let's see what it looks like! What You'll Do: Design and maintain Solution Design References (SDRs), data layer recommendations, and technical specification documents that serve as the source of truth for tracking implementations across web and app properties. Implement and validate analytics tags and marketing pixels using Google Tag Manager, covering both client-side and server-side setups, with strong QA discipline at every stage. Experience configuring and validating cross-domain tracking in GA4, including referral exclusions, linker parameters, and session continuity across multi-domain client environments. Write JavaScript, ES6, and jQuery functions to capture required data from web pages, and troubleshoot discrepancies between what the implementation says and what GA4 reports show. Build and run analyses in GA4 and BigQuery, going beyond surface-level reporting to surface the behavioral patterns and conversion drivers that matter, including custom explorations, segments, and funnel analysis. Manage and mentor a small team of analysts and implementation engineers, reviewing their work, unblocking technical problems, and helping them grow their skills in both implementation and analysis. Partner with clients and internal stakeholders to gather analytics requirements, translate them into scoped technical projects, and produce Point of Views (POVs) on measurement trends or platform changes as needed. Stay current on privacy-driven shifts in measurement, including consent mode, server-side tagging, and cookieless tracking, and bring practical responses to those changes into the team's standard approach. Experience building and maintaining proactive monitoring infrastructure, including Looker Studio dashboards and GA4 or GTM-based alerts, to detect data quality issues such as traffic drops or tag failures across multiple client properties before clients report them. Who You Are: What We Really Want: Someone who still enjoys the implementation craft but is ready to be responsible for more than their own output. You can write a data layer spec, spot a broken tag, and explain what the data means to a non-technical stakeholder, all in the same week. You've managed a small team or mentored others and you're ready to do it more formally. What Particular Set of Skills Would Suit This Role: 2-4 years in digital analytics, with strong hands-on experience in GA4 and Google Tag Manager across both client-side and server-side implementations. Deep working knowledge of GA4, including event modeling, custom dimensions, exploration reports, and the differences from Universal Analytics. Solid JavaScript, ES6, and jQuery skills sufficient to write and debug tag implementations without leaning on front-end developers. Comfortable in BigQuery and SQL for data extraction, transformation, and analysis beyond what GA4's UI surfaces. Experience with server-side tagging via GTM Server and working knowledge of consent management platforms (CMPs). Familiarity with mobile app analytics implementation using Firebase or AppsFlyer. Exposure to additional TMS platforms such as Tealium or Adobe Launch is a plus, as is experience with CDPs like Tealium AudienceStream or BlueConic. A track record of producing clean technical documentation, including SDRs and tag collection guides, that others can actually work from. Some experience managing or mentoring others, formally or informally. How You Succeed: You're succeeding when the tracking is solid, the documentation is trusted, and the analysis is changing how people make decisions. Your team ships clean implementations, QA is thorough before anything goes live, and stakeholders come to you first when something looks wrong in the data or a new measurement requirement lands on the table.
