The Sr. Product Marketing Manager leads portfolio strategy for T-Mobile Fiber, a strategic pillar of T-Mobile’s broadband business, with ownership over the products and strategies that win new customers, grow ARPU, and set T-Fiber apart from cable and fiber incumbents.

This role sits at the center of product strategy, consumer insights, and go-to-market, turning emerging customer needs, market whitespace, and industry shifts into product concepts, value propositions, and a long-term roadmap, each backed by a business case that holds up to financial scrutiny.

The role takes products from idea through launch and into market, influencing marketing plans and driving feature builds alongside Product, Operations, Pricing, Consumer Insights, Analytics, Competitive Intelligence, Integrated Marketing, Sales, and Acquisition, then tracking performance to keep the portfolio growing.

The ideal candidate is a strategic marketer and business thinker with sharp analytical skills, strong storytelling, and a passion for uncovering unmet customer needs, who thrives in ambiguity and influences across a large organization.

This position requires a hybrid work arrangement – working at the designated office location at least 3 days per week.
