Job Description
You report into the Martech Solutions Architect and work day-to-day with the Engineering Team and Analytics team, who set technical design and standards, and with the analytics and client management teams who own measurement strategy and the client relationship.
Marketing measurement only works if someone keeps it working. Tags fire, servers run, pipelines land data at three in the morning, and when one of them stops, a client loses visibility of their business. The MarTech Engineer implements that plumbing and keeps it healthy.
The role sits across two things that are usually held by different people. On one side, tagging and measurement implementation: data layers, GTM web and server-side, GA4, conversion APIs and consent. On the other side, the cloud services those implementations run on: containers, scheduled functions, alerting and the daily reality of keeping a managed estate up. If you have run server-side tagging in production, you have probably already done both.
You will work alongside a MarTech Solutions Architect who owns solution design. Your job is to implement it, run it, and be the person who notices when something is wrong before the client does.
Responsibilities
-
Keep a managed estate of client services healthy: monitoring, alert response, scaling, container and server updates, and backfills when something has gone wrong.
