The Marketing Technology Department's mission is to "maximize marketing results through technology and data," covering website development, measurement environments, and data visualization and analysis.

• Build working prototypes in short iterations (hours to days) and refine specifications while validating with users

• Design evaluations that balance business KPIs (leads, CVR, effort reduction) and AI-specific metrics (accuracy, response time, cost), and prepare Go/No-Go decision material

• Implement solutions in regular use on the internal AI marketing tool platform and run them stably in production

• Own operational design including monitoring, logging, cost management and access control, and keep improving after rollout

• Contribute knowledge and successful patterns back to the platform as shared modules, reference implementations and templates

• Experience building and operating systems in production on AWS, GCP or Azure, including CI/CD, monitoring, permission design and cost management

• Implementation experience using AI coding tools such as Claude Code

• Ability to discuss trade-offs between individual requests and platform-wide optimization in technical terms and build consensus with stakeholders
