Identify opportunities for AI implementation (e.g., automation, personalization, content workflows), execute implementations and partner with internal teams on roll-out

Research and test new tools and frameworks that support AI and marketing technology integration

Maintain documentation, enforce data governance, and validate data quality

Collaborate with cross-functional teams including analytics, media, strategy, and account service

Mentor junior developers and support technical decision-making across projects

Ability to manage multiple projects in a fast-paced, collaborative environment

Preferred Experience:

Salesforce Marketing Cloud certification (or willingness to achieve it shortly after hire—agency-supported)
