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!

Grant Street Group is an innovative and rapidly growing software company that supports government agencies and financial institutions through specialized SaaS solutions focused on tax collection, electronic payments, and more. Our work is meaningful, complex, and highly collaborative — and we are looking for a Senior Project Manager to lead large, high-impact implementation programs across multiple clients and teams. The project portfolio may include mergers and acquisitions, strategic partnerships, and integrations, as well as other major business initiatives. M&A work is anticipated, though it may not begin immediately; this role will lead other strategic projects as business priorities require.

This is not a coordination-only role. We are seeking someone who can independently lead complex initiatives from planning to execution, drive M&A-related work forward, manage risk proactively, align stakeholders, and adapt to shifting priorities.

Successful candidates will bring strong leadership, communication, and organizational skills along with experience managing large-scale, cross-functional initiatives related to mergers and acquisitions, integrations, enterprise transformation, or similarly complex business operations.

Required Qualifications

8+ years of project/program management experience in M&A, corporate development, consulting, financial services, enterprise technology, operations, or similarly complex environments

Prior experience leading an M&A project

Experience leading or supporting merger, acquisition, integration, or other high-visibility cross-functional initiatives

Ability to operate independently in fast-moving environments with evolving priorities

Excel at building alignment across technical and non-technical stakeholders

Strong communication skills, including the ability to explain complex topics clearly and simply to executives, teams, and external partners

Sound judgment and discretion when managing sensitive or confidential initiatives

Experience managing projects involving multiple systems, functions, vendors, and cross-functional dependencies

A highly organized, flexible and pragmatic approach, with the ability to balance strategic thinking and hands-on execution

Proactive problem solver who anticipates issues before they become roadblocks

Experience recovering or stabilizing challenged projects/programs or navigating ambiguity during periods of organizational change

Preferred Experience

Experience with due diligence coordination, integration planning, and post-close execution

Experience with change management, process improvement, or operational integration efforts

Experience in SaaS, software, financial services, or other regulated industries

Experience managing distributed or remote teams

PMP or related project management certifications are welcome but not required
