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.
This role can be based in New York City, Austin, or Palo Alto for our hybrid working model or remotely in the United States.
What You'll Do
Integration Strategy & Planning
Partner with Corporate Development from LOI onward to translate the deal thesis into clear integration goals, success criteria, and a high-level operating model for each transaction
Build and maintain MongoDB's integration playbook — standard plans, Day 1/Day 100 checklists, communications templates, and KPI frameworks — refining it deal by deal alongside the Chief of Staff
Support governance for each transaction, including defined workstreams, a master integration plan, and clear DRIs (Directly Responsible Individuals) by function

In favour: Occupation is eligible for Skilled Worker
Occupation code 2431 (Management consultants and business analysts) is eligible for the Skilled Worker route on the rules in force from 11 Nov 2025.
Immigration Rules Appendix Skilled Occupations
Against: Estimated salary is below the going rate
No salary is stated, so this uses an estimate of £48,058 from ASHE estimate (low end of the senior band) (1 Apr 2025). It falls £2,142 short of the going rate for occupation code 2431 of £50,200. Because that salary is estimated rather than stated, this rule counts half.
