JOB DESCRIPTION Reporting to our Analytics Director, you will create impact in the Analytics Team, within our Martech Capability. We take pride in our work with some of the largest advertisers in APAC, setting us apart in the industry. The Senior Analytics Manager owns the measurement approach across a set of enterprise accounts. You are the person the team escalates to, and the person clients ask for when the question is hard. You still build, but your value is in the design, the standard you hold others to, and the people you bring up behind you. At Jellyfish, we are committed to promoting professional growth. Your career path could lead to becoming the global subject matter expert for the latest advanced technical solutions. YOUR PRIMARY RESPONSIBILITIES WILL INCLUDE: Technical consulting and subject matter expertise - Own the measurement conversation with senior client stakeholders across your accounts. Shape the brief before it becomes a brief, and connect measurement decisions to the commercial outcome the client is chasing. - Be the escalation point in market for the hardest technical questions, and the person who says no to a solution that will not hold. - Set the point of view the team takes to clients on platforms, privacy and AI, and keep it current as those change.

Tag management - Lead server side GTM migrations: container design, hosting on Google Cloud, Cloudflare or a managed provider, and event transport into conversion APIs such as Meta Conversions API, Google enhanced conversions and TikTok Events API.

SQL and analysis - Strong SQL. Design the warehouse models and reporting datasets your accounts run on, and review the queries behind any number that goes to a client. - Turn analysis into a recommendation a senior marketer will act on, and be clear about how much confidence it deserves. Modern measurement - Recommend and scope the right measurement approach for a client question, across platform attribution, incrementality and holdout testing, geo testing, causal impact analysis and marketing mix modelling. - Design and run incrementality and geo tests, and brief the specialists who build the models on what the model needs from your data. - Interrogate results before a client sees them. Know where a method breaks down and say so.
