Senior Project Manager, M&A & Large Projects

Are you an experienced senior project manager who can lead M&A projects as well as other large, complex projects? Do you thrive in environments with many moving pieces, competing priorities, and high visibility? Do you enjoy leading cross-functional initiatives, building trust with stakeholders, and helping teams navigate ambiguity to deliver outstanding results? If so, we’d love to hear from you!
