About the Opportunity

Our client, an established professional services organization headquartered in Chicago, is seeking a Senior Microsoft 365 Engineer to join its Infrastructure and Engineering team.

This is a senior-level, hands-on engineering opportunity focused on designing, implementing, securing, and optimizing enterprise Microsoft 365 solutions, with a strong emphasis on Microsoft Power Platform, specifically Power Apps and Power Automate.
