  • Support and quality-assure large-scale CMS initiatives (e.g., Adobe Experience Manager) including analytics/tag migration, content instrumentation, and release validation

  • Establish and maintain ongoing monitoring, alerting, and SLAs for data quality; create documentation, playbooks, and Confluence dashboards; deliver training and evangelize data collection and governance best practices
  • Diagnose technical issues using JavaScript, DevTools, Charles/Fiddler, and network analysis; design and deploy fixes through Agile release processes
  • Collaborate with Legal/Privacy, InfoSec, and Risk to align implementations with policy, DPIAs, vendor assessments, records of processing, and data subject request workflows
  • Work within and help improve Agile practices (story writing, backlog grooming, sprint ceremonies) across the MarTech and partner engineering teams


What We’re Looking For


  • 5+ years in tag management/MarTech/analytics engineering, including 3+ years hands-on with Tealium iQ and strong JavaScript skills
  • Demonstrated experience designing and deploying GDPR/CCPA-compliant consent and exclusion systems across web and mobile; practical knowledge of CMPs (e.g., OneTrust, TrustArc), IAB TCF, and GPC
  • Proven ability to architect and operate tag meta-monitoring with ObservePoint: automated audits, journeys, data layer validation, alerting, API usage, and health reporting (e.g., Confluence)
  • Experience supporting AEM (Adobe Experience Manager) implementations or migrations, including analytics and tagging strategy, content QA, and deployment coordination
  • Strong background in data layer design and governance; event taxonomy, schema versioning, and documentation
  • Hands-on experience with mobile tagging and SDKs (e.g., Tealium, Adobe, Firebase), and collaborating with iOS/Android engineers on instrumentation
  • Familiarity with digital advertising/MarTech ecosystems and integrations (e.g., CM360/Floodlight, Google Ads, Meta, LinkedIn, Bing, Salesforce, Braze, Branch/Adjust)
  • Proficiency with debugging and testing tools: Chrome DevTools, Charles/Fiddler, network proxies, Postman; solid understanding of cookies/storage, consent modes, and client/server data flows

  • Excellent communication and stakeholder management skills; ability to translate business requirements into technical specs and mentor peers
