Gmp Platform Support Specialist

JOB SUMMARY

We are looking for a GMP Support Specialist to act as the frontline technical and operational expert across our Google Marketing Platform stack (SA360, CM360, and DV360). This role sits at the intersection of platform support, billing accuracy, and client communication — owning the day-to-day resolution of platform issues, validating billing data ahead of month-end close, and ensuring clients have a reliable, responsive point of contact for all GMP-related queries.

This is a hands-on, detail-driven role suited to someone who is equally comfortable troubleshooting a tracking discrepancy, managing an inbound support queue, and reconciling a billing report ahead of a Finance deadline.

JOB RESPONSIBILITIES

• Serve as the first point of contact for client queries across SA360, CM360, and DV360, diagnosing and resolving platform issues relating to campaign setup, trafficking, tracking, reporting, and user access in a timely and accurate manner.
• Review and validate month-end billing reports exported from GMP platforms against expected spend and licence data, ensuring accuracy before handoff to the Finance team and flagging discrepancies for investigation.
• Manage an inbound support queue, prioritising and triaging client requests, communicating resolution timelines clearly, and escalating complex technical issues to platform or vendor contacts where required.
• Support the setup and maintenance of user accounts, permission structures, and advertiser/account hierarchies across GMP platforms, ensuring correct access levels are applied in line with client and contractual requirements
• Conduct regular QA checks on platform data — including impression, click, and conversion tracking integrity — to ensure reporting outputs are reliable and consistent across tools.
• Work closely with Finance, Delivery, and Client Services teams to ensure platform data aligns with invoicing requirements, resolve billing queries, and contribute to month-end close processes accurately and on schedule.
• Support Looker Studio (Data Studio) reporting, including troubleshooting first-level issues such as user access and report connectivity. (Highly desirable, not essential.)

QUALIFICATIONS

• 3+ years' experience working with Google Marketing Platform (SA360, CM360, DV360) in a support or operations role, dealing directly with clients.
• Strong working knowledge of campaign trafficking, tracking implementation, and reporting across GMP tools.
• Excellent written and verbal communication skills, with the ability to explain technical issues clearly to non-technical stakeholders.
• Proven ability to manage competing priorities in a queue-based support environment, with clear and proactive client communication on timelines.
• High attention to detail, particularly when validating billing and spend data against contractual or licence terms.
• Proactivity and initiative to investigate and resolve issues with limited guidance, escalating appropriately when needed.
• Comfortable working cross-functionally with Finance, Delivery, and Client Services teams.

NICE TO HAVE:

• Experience with Looker Studio (Data Studio), including report setup, troubleshooting, and access management.
• Familiarity with billing and reconciliation processes in a media, ad-tech, or agency environment.
• Experience with user/permission administration across enterprise advertising platforms.
