Media Data and Insights (MDI) is T-Mobile's data and AI team for paid media and search — turning massive amounts of data into reliable, AI-augmented insights that drive decisions across the media organization. We own the full data lifecycle from gold-layer transformation through executive-ready reporting, partnering across Media Analytics, Media Enablement, and Engineering to deliver one consistent story of what's working, what isn't, and why.

As the Sr. Business Analysis Manager, Technical Lead, you will be the senior technical partner who makes MDI's data production-ready and trustworthy. You will own the architecture, automation, and technical rigor that ensures our data is reliable, fully automated, and powering the BI and insights the business depends on every week.

In this role, you'll set the technical standards that move the team from manual maintenance to scalable, automated infrastructure — freeing us to deliver higher-value insights faster. You'll partner with peers across Media Analytics, Media Enablement, and Engineering as we deliver major 2026 initiatives across executive reporting, cross-channel media and web behavior insights, and a major clickstream data platform transition.

Key Responsibilities

Technical Architecture and Standards

Major Initiative Leadership

Serve as the technical lead for major data platform transitions, cloud migrations, and consolidating media reporting infrastructure across teams.

Construct executive-level summaries of technical strategy and present complex architectural decisions in clear, concise terms to non-technical stakeholders. Possess the ability to influence leadership through fact-based recommendations.
