The Sr Consultant, Organizational Capability is a senior change effectiveness leader responsible for shaping how people experience transformation at T-Mobile—most critically across mergers and acquisitions, and selectively across enterprise HR priorities. This role serves as the HR lead for M&A change, communications, and organizational design, owning the end-to-end strategy and execution that enables new employees, leaders, and teams to integrate seamlessly and perform at their best. More than a change practitioner, this role is a change architect and builder—designing the integration narrative, developing differentiated change and communications products, and orchestrating experiences that turn complexity into clarity and uncertainty into momentum. The Sr Consultant partners closely with senior HR and business leaders to diagnose change impacts, shape organizational solutions, and deliver practical, human-centered interventions that drive adoption, engagement, and sustained performance. With accountability from strategy through delivery, this role ensures that every integration and HR-led transformation reflects T-Mobile’s culture, values, and Magenta Magic—executed with rigor, creativity, and measurable impact. This is a career-defining opportunity for a proven change leader who thrives in ambiguity, elevates the practice of change management, and sets the standard for how transformation is done at scale.
