Sr. Business Analysis Manager - Technical Lead

This position must be located in Bellevue, WA. This is not a remote role — this is a hybrid schedule requiring at least 3 days a week in office.

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.

• Production‑Ready Data Infrastructure – Build and maintain reliable, automated pipelines in Databricks that don’t require constant manual intervention. Establish monitoring, alerting, and SLAs that make our data the source of truth leadership depends on.
• Clickstream Data Validation & Partnership – Partner closely with Engineering on enterprise clickstream tables (pageview, visit, and user‑level) – defining MDI’s requirements, validating outputs, and ensuring data quality so the team can analyze web behavior and media impact at scale.
• Data Quality Framework – Establish testing, validation, and anomaly detection standards so our data is trusted across the organization. Lead QA against ingestion pipelines, data sources, and platform UIs.
• Cross‑Team Alignment – Partner with peer analytics teams to align on shared conventions and standards, ensuring consistency between macro‑level analytics and diagnostic reporting.
• Technical Mentorship – Provide guidance and uplift the technical capabilities of the broader team. Set the technical standard and help less senior team members grow into it.
• Major Initiative Leadership – Serve as the technical lead for major data platform transitions, cloud migrations, and consolidating media reporting infrastructure across teams.
• Executive Communication – 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.
