About the Role

MongoDB is seeking a Senior Manager, M&A Integration to build and manage the operational framework for integrating acquisitions, ensuring each deal translates into a successful business outcome. This role involves leading integration planning and execution from LOI through post-close, coordinating across all functional teams, and supporting the Integration Management Office (IMO) to define workstreams and build the master integration plan.

Responsibilities

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.
Serve as the day-to-day integration lead for assigned deals, supporting the governance cadence (standups, cross-functional reviews, status updates) and holding business owners across Legal, HR, Finance & Accounting, IT, Go-to-Market, Marketing, and Product & Technology accountable to plan.
Manage dependencies and risks across workstreams, help facilitate decisions and trade-offs across teams, and escalate material issues to the Chief of Staff and Corporate Development.
Own Day 1 and Day 100 readiness for assigned transactions, prioritizing across concurrent deals as needed.
Partner closely with HR on Day 1 planning, org design and role mapping, and retention and engagement plans for critical acquired talent.
Track talent risk indicators — attrition, engagement, manager feedback — and flag concerns and recommended interventions to protect the acquired team’s strengths.
Serve as a steady point of contact for acquired employees during transition, helping them navigate MongoDB and connect with the right stakeholders.
Track integration KPIs per deal and partner with Corp Dev and FP&A to tie progress back to the original deal thesis and financial model, calling out variance and recommended course corrections.
Maintain a deal-level view of status, risks, and interdependencies, and support the Chief of Staff in maintaining a portfolio-level view across active integrations.
Present integration status and progress for assigned deals, in partnership with the Chief of Staff, to relevant stakeholders.
Build and maintain MongoDB's integration toolkit — standard plans, checklists, templates, and KPI libraries.
Engage early in the deal lifecycle to assess integration complexity and risk, and highlight integration implications during evaluation and negotiation.
Use AI-enabled tools to help standardize and scale playbooks, trackers, and governance templates for future transactions.
Contribute to retrospectives after major integrations and help incorporate lessons learned.

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.
