We're looking for an Exchange Specialist with the technical chops and real-world experience to design and build a hybrid Exchange environment. This is a hands-on role for someone who's done this before and knows the difference between "it works in theory" and "it works in production."
You'll be working as part of a project delivery team to implement a secure, scalable hybrid Exchange solution - integrating on-prem Exchange with Exchange Online, ensuring seamless coexistence, mail flow, and identity synchronization.


Key Responsibilities

  • Design, build, and configure a hybrid Exchange environment (on-prem + Exchange Online).
  • Lead migration planning and execution for mailboxes, distribution lists, and shared resources.
  • Implement best practices for security, authentication, and compliance (MFA, DKIM, SPF, DMARC, etc.).
  • Work closely with Infrastructure and Security teams to integrate with Active Directory and Azure AD.
  • Troubleshoot complex mail flow and hybrid connectivity issues.
  • Document the environment, configuration, and migration procedures.
  • Provide knowledge transfer and guidance to in-house IT teams.

Required Skills & Experience

  • Proven experience designing and implementing hybrid Exchange environments (Exchange 2016/2019 + O365).
  • Deep understanding of Exchange Online, Azure AD Connect, and mail routing.
  • Strong knowledge of PowerShell for automation and administration.
  • Familiarity with M365 security & compliance features.
  • Comfortable working independently and remotely, with occasional travel to Dublin for key project phases.
  • Excellent communication skills - clear, direct, and able to translate tech into action.
