What We're Looking For
The ideal candidate is a senior Microsoft 365 Engineer or Architect who has successfully led enterprise Microsoft 365 migrations and modernization initiatives. You should possess deep technical expertise across the entire Microsoft 365 ecosystem and be comfortable driving architecture decisions, implementing secure solutions, and leading complex transformation projects from planning through execution.
