T-Mobile•TX-Remote, IL

3d•$80,600 - $145,500•Onsite

About The Position

At T-Mobile, we invest in YOU! Our Total Rewards Package ensures that employees get the same big love we give our customers. All team members receive a competitive base salary and compensation package - this is Total Rewards. Employees enjoy multiple wealth-building opportunities through our annual stock grant, employee stock purchase plan, 401(k), and access to free, year-round money coaches. That’s how we’re UNSTOPPABLE for our employees! T-Fiber is growing fast. As our Sr. Analyst, Business Intelligence, you'll be the person who turns raw market data into a clear, honest story about how we're performing and, more importantly, why. This isn't a reporting-only role. You'll dig into penetration rates, add rates, churn, preorder cancel rates, and competitive dynamics to surface the insights that drive real decisions. You'll report to the Sr. Commercial Marketing Manager and work closely with Fiber business leaders. You'll own the data, build the analysis, and prepare the executive-ready presentation — your manager or a business leader will deliver it, but the clarity and credibility of that story starts with you. T-Fiber is T-Mobile's push into fixed broadband — and we're moving fast. You won't be maintaining a legacy reporting stack. You'll be building the analytical foundation of a growing business, working with data that directly shapes how we compete across markets. If you want ownership, visibility, and the chance to see your work influence real decisions, this is the role.

Requirements

Prioritization and organization: Ability to manage multiple projects simultaneously, and deliver under tight timelines in a fast-paced environment. You'll juggle recurring reports, ad hoc requests, and long-horizon analysis simultaneously — often all at once
Independent execution: We're a lean team. You'll be expected to self-direct, identify what needs to get done, and do it
Data analysis and interpretation: Strong analytical mindset with ability to interpret trends across penetration, conversion, churn, and subscriber growth drivers. The job is finding what the data means, not just what it says
Business problem identification: Strong business acumen and understanding of go-to-market performance levers. We need someone who spots the issue before being asked, not after
Communication across levels: Ability to translate complex datasets into clear, compelling executive narratives. Your work goes to operators and executives — you need to code-switch between technical depth and plain language
Excel: Pivot tables, large dataset modeling, performance trending — this is a daily tool
Power BI / Tableau / QuickSight: Your primary visualization stack — proficiency in at least two is expected
Performance modeling: Building models that answer 'what happens if...' questions around market performance — not just documenting what happened
Bachelor's degree plus 5 years of related work experience OR Advanced degree with 3 years of related experience; acceptable areas of study include Business, Statistics, Economics, Data Analytics or similar degree
4 years of data analysis, business intelligence, or performance reporting experience
4 years of SQL experience with performant querying of large datasets
4 years of Tableau (or similar BI tool) dashboard development and data visualization
Advanced proficiency in Microsoft Excel and PowerPoint
Experience building presentations or reports for a senior or executive-level audience, and contributing to executive-level business reviews
Experience working with large-scale data environments (e.g., AWS Redshift, Azure, Databricks)
Experience analyzing telecommunications, broadband, or subscription-based businesses
Familiarity with competitive intelligence, market demographics, or socioeconomic data sources
Background in a startup or high-growth environment where ambiguity is the norm
At least 18 years of age
Legally authorized to work in the United States
