About The Position

As Senior Manager of M&A Integration, you'll serve as the operational quarterback for JLL's acquisition integrations, transforming deal strategy into seamless execution.

You'll build the playbooks, drive accountability, and track the metrics that turn acquisitions into strategic wins. If you thrive in fast-paced environments where your ability to orchestrate, problem-solve, and deliver measurable results directly impacts JLL's growth trajectory, this role offers significant visibility and impact across the organization.
