Principal Product Manager

Responsibilities

• Owns the learning agenda for the entire portfolio, extending beyond a single area. Tracks quarterly bets, confirms or refutes outcomes with data, and defines the next direction for the portfolio. Takes personal accountability for the portfolio OKRs.
• Approaches each quarter as a learning cycle at portfolio scale, articulating hypotheses across multiple product areas, tracking outcomes, and updating multi-year strategy based on data findings.
• Defines what strong PM practice looks like across the organization and establishes the reference standard for discovery, hypothesis formation, outcome ownership, and AI directive quality.
• Demonstrates AI fluency at scale, including directive writing, agent-assisted competitive research, and portfolio-level analytics. Showcases how frameworks and standards uplift PM performance and coaches others on AI output quality.
• Anticipates market and technology shifts ahead of obvious priorities, providing a forward-looking view that informs multi-year strategic bets.
• Identifies new problem spaces by reading customer, market, and competitive signals to uncover gaps not yet on any roadmap, building a data-backed case for net-new opportunities.
• Acts as an independent co-owner of customer research direction, participating in research and producing a synthesized view that links customer signals to portfolio-level strategy.
• Understands where T-Mobile leads, where it lags, and where the category is moving before priorities become obvious, using this knowledge to guide the organization.
• Advances a customer-first standard across the PM organization, creating conditions where teams rely on customer evidence rather than assumptions.
• Shapes portfolio and multi-year product strategy by synthesizing competitive dynamics, customer signals, and market timing into a clear strategic direction, deciding which bets to accelerate or stop.
• Builds frameworks and tools that enable others to think strategically in the same way, enabling independent decision-making across the PM community.
• Owns the portfolio roadmap across multiple Agile teams, managing cross-team and cross-platform dependencies and aligning prioritization at an enterprise level.
• Connects portfolio strategy to business outcomes, defending direction with evidence, updating it when data indicates, and communicating the rationale transparently.
• Leads external discussions on partnerships, licensing, and market positioning, representing T-Mobile's product strategy at the industry level.
• Forges cross-organizational relationships to unlock strategic leverage for the portfolio, influencing direction through credibility and sustained collaboration.
• Engages with executives from VP level down, presenting an evidence-backed strategic narrative to inform decisions and build trust.
• Partners with Architecture, Engineering, and Platform teams to ensure coherent technical strategy across the portfolio and protect enterprise platform health.
• Identifies systemic organizational issues that hinder portfolio success and drives resolution with a recommended solution.
• Communicates product vision and portfolio strategy to Directors and VPs, tailoring the message to the audience while preserving clarity of the argument.
• Makes the portfolio tangible to the executive team as a coherent strategic argument for direction and impact.
• Drives ad hoc analyses and presents strategic recommendations to VP level as positions to defend and own, not merely data presentations.
• Communicates technical challenges and tradeoffs at the portfolio level, surfacing issues early with a clear path forward.
• Is accountable for product quality and timely response across the portfolio during high-impact issues, including executive communications.
• Maintains a deep understanding of data to translate portfolio-level insights into a narrative about what to measure and why, shaping the portfolio direction.
• Identifies enterprise-scale opportunities supported by data and builds a VP-level argument for pursuing them, owning outcomes after bets are placed.
• Owns the portfolio KPI framework, defining metrics across product areas and how they aggregate into business outcomes.
• Conducts ROI, NPV, and cost-benefit analyses to inform major multi-product investments, building financial models for enterprise-level decisions.
• Uses data to tell an honest story about portfolio performance, including areas to stop investing in.
• Owns outcomes across the most complex, ambiguous, and cross-platform challenges, accountable for the full arc of the portfolio without requiring executive direction to act.
• Ensures timely resolution of complex problems that deliver customer value and maintain accountability for outcomes.
• Translates portfolio strategy into detailed capabilities and features consumable by engineering across multiple Agile teams, with prototyping as a standard tool.
• Defines standards for PM practice and sets a reference point for discovery, hypothesis, ownership, and AI directive quality.
• Mentors Senior PMs and PMs, delivering direct feedback and raising the organization-wide standard for problem framing, ownership, and strategic thinking.
• Applies AI fluency at portfolio scale and coaches others on output quality, demonstrating impact of AI standards on team performance.
