• Demonstrated expertise implementing and managing identity security controls, including Conditional Access, Identity Protection, Privileged Identity Management (PIM), Access Reviews, Entitlement Management, Authentication Strengths, and Zero Trust security architectures.
• Strong organization and attention to detail across concurrent work.
• Analytical, proactive problem-solving; sound judgment when something "doesn't look right."
• Ability to prioritize effectively, communicate clearly, and delegate when appropriate.
• A service-focused mindset, curiosity for continuous improvement, and commitment to supporting secure, reliable banking.

A Typical Day

It may be hard to pinpoint what a typical day will be as a Microsoft Identity and Cloud Security Administrator because your day could vary. A priority will be to ensure Mercantile Bank's Microsoft environment is secure, stable, and ready for the employees and customers who rely on it. You will do this by reviewing overnight alerts, security dashboards, patch or vulnerability items, and identity signals to identify what needs attention, what can be improved, and where follow-up is needed.

Your day will shift between focused project work and time-sensitive troubleshooting. You might be refining Microsoft Defender policies, reviewing Entra ID access controls, supporting eDiscovery requests in Purview, documenting decisions for audit readiness, or partnering with Information Security to reduce risk and strengthen controls.

You'll collaborate regularly with teammates, IT leadership, vendors, and business partners to keep work moving from planning through rollout. Some days will call for calm problem-solving and quick prioritization; others will focus on improving processes, sharing knowledge, and helping the broader technology team build secure, dependable systems that support meaningful work in the communities Mercantile Bank serves.
