About The Position

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. As the Senior Manager, M&A Integration, you’ll help ensure acquisitions are integrated successfully and that the value outlined in each deal is realized. You may provide input during diligence to help flag integration risks, and you will lead integration planning and execution from LOI through post-close for assigned deals, reporting to the Chief of Staff to the CFO and partnering closely with our Corporate Development team. You'll coordinate across every functional team involved in a deal — Legal, HR, Finance & Accounting, IT, Go-to-Market, Marketing, and Product & Technology. You and the Chief of Staff together will support the Integration Management Office (IMO): defining workstreams, building the master integration plan, and supporting governance cadence for each deal. This is a hands-on execution role with real ownership of individual deal integrations. You’ll help build out MongoDB’s integration playbook – standard plans, checklists, templates – turning deal-by-deal efforts into more consistent, repeatable practices alongside the Chief of Staff. This role is ideal for someone who has led M&A integration workstreams before and knows how to bring structure to the ambiguity of a newly closed deal. You know how to drive cross-functional execution without formal authority, operate with autonomy within a defined framework, move fluidly between Day 1 planning, synergy tracking, and status reporting, and take ownership of outcomes rather than waiting to be told what to do. This role may flex across multiple concurrent deals depending on the pace of acquisitions.

Requirements

Bachelor's degree required with a minimum of 8 years of progressive professional experience, including at least 5 years leading or directly supporting M&A integration, post-merger integration consulting, corporate development integration, or complex cross-functional transformation programs.
Experience owning integration workstreams or full integrations for individual deals, with clear accountability from planning through post-close execution
Experience partnering with Corporate Development from LOI through close
Experience across deal types, including product and talent tuck-ins
Strong program management discipline — structured planning, risk and dependency management, and clear, concise communication of status, trade-offs, and recommendations
Comfort operating cross-functionally and presenting status to senior stakeholders, with autonomy within a defined framework
Cross-functional depth across Legal, HR, IT, Finance & Accounting, Go-to-Market, Marketing, and Product & Technology, including experience managing sensitive situations with acquired leaders and employees
Change management experience — comfortable with the people and cultural side of integration, not just process and systems
High-ownership, low-ego operator who thrives in ambiguous, deal-driven environments
Highly trustworthy — you exercise sound judgment and discretion working on confidential transactions

Experience within a technology or software organization is strongly preferred
