Senior Manager, M&A Integration

About the role

MongoDB is hiring a Senior Manager, M&A Integration to help build and run the operational backbone for how MongoDB integrates its acquisitions, translating each deal thesis into a durable business outcome. In this role, you will own the end-to-end integration of assigned acquisitions, ensuring that the strategic value defined during diligence is realized post-close. You will act as the operational backbone for the Integration Management Office, translating deal strategy into actionable plans and accountable execution.

You will work in a hybrid environment with the flexibility to be based in New York City, Austin, Palo Alto, or remotely within the United States. This role is designed for an operator who thrives in ambiguity and turns complex cross-functional efforts into repeatable processes.
