Project Manager - IT Infrastructure

We're looking for an IT Infrastructure Project Manager to lead an M&A integration engagement for a client in the greater Los Angeles area. The work involves bringing a newly acquired company onto the client's existing enterprise infrastructure across a defined Day 1-90 window, ensuring a smooth transition for staff and technology alike.

This is a general contractor role, not a deep specialist one. You'll coordinate the work streams, manage the execution teams, and keep the integration on track - while also building the playbook that standardizes how future acquisitions get onboarded. If you have deep expertise in one of the technical domains below, even better.

This role is on a contract basis, preferably as a 1099 independent contractor.

• Lead the Integration: Own the project plan, stakeholder communications, and coordination across all technical work streams from Day 1 through 90-day stabilization.

• Act as General Contractor: Manage and align execution teams across systems, network, security, and identity work streams - you don't need to be the specialist in everything, but you need to keep everything moving.

• Drive Microsoft Environment Merges: Oversee the integration of Outlook, SharePoint, Active Directory, and domain migration into a single-tenancy environment.

• Coordinate Network & Security Standup: Manage execution across firewall configuration, VPN redirection, server migrations, and network security setup.

• Oversee Identity & Support Scaling: Ensure IAM is set up correctly and that help desk operations are resourced and ready for the post-acquisition surge.

• Build the Playbook: Document the integration process into a reusable acquisition onboarding playbook - a repeatable asset the client can apply to future acquisitions.

• IT Project Management
  
  Experience:
  
  Proven track record managing technology infrastructure projects - ideally including M&A integrations, system migrations, or enterprise IT standup programs.

• Microsoft Environment Familiarity: Working knowledge of Microsoft 365 environments - Active Directory, Outlook, SharePoint, and domain migrations - enough to understand scope, sequence dependencies, and risk.

• General Contractor Instincts: You don't need to be the deepest specialist in the room, but you need to know enough about firewalls, VPNs, IAM, and server migrations to coordinate execution teams effectively and catch problems early.

• Specialist Depth (Nice to Have): Deep expertise in any one of the domains above - network/security, Microsoft environments, IAM, or IT operations - is a meaningful differentiator.

• Stakeholder & Vendor Management: Comfortable managing up to client leadership and across technical execution teams simultaneously. You keep people aligned without slowing them down.

• Documentation Discipline: Able to build structured, reusable process documentation - this phase ends with a usable playbook, not just a project.

• Local Presence: Based in LA, Orange County, or San Diego, with the ability to be on-site as needed throughout the engagement.
