About The Position

EOS IT Solutions is a global technology and logistics company providing collaboration and business IT support services. This contractor role will help establish a secure, well-governed, and supportable identity and collaboration environment. Working across Operations, Engineering, IT, and Security, the Systems Engineer will help transform an organically grown Microsoft Entra environment into an enterprise-ready platform. The engagement is fixed-term and outcome-focused.

The role includes assessing the existing Microsoft Entra and Microsoft 365 environment, prioritizing and implementing approved improvements, strengthening security visibility, and documenting and handing over the target state so Operations and Engineering teams can maintain it.

Requirements

• Expert-level experience managing Microsoft Entra ID in complex or enterprise environments, including tenants requiring governance uplift.
• Strong understanding of Microsoft 365 licensing, entitlement management, administrative roles, Conditional Access, and least-privilege principles.
• Proven ability to design and implement privileged access controls, including Privileged Identity Management (PIM), role activation, approval workflows, and access reviews.
• Hands-on experience integrating identity providers such as Okta with Microsoft Entra, including SCIM provisioning, lifecycle management, and troubleshooting.
• Strong scripting and automation capability using tools such as PowerShell, Microsoft Graph API, or equivalent automation platforms.
• Practical experience securing and governing Microsoft Teams, SharePoint, OneDrive, and other Microsoft 365 workloads.
• Experience reviewing audit and security logs, integrating Microsoft cloud telemetry with SIEM platforms, and improving detections and operational visibility.
• Working knowledge of Azure cloud management, including discovering existing usage, assessing governance and security posture, preventing unmanaged adoption, and providing oversight and control rather than large-scale cloud operations support.
• Ability to produce clear technical documentation, operating procedures, control descriptions, and training materials.
• Comfort working independently in a short, outcome-focused, fixed-term engagement.

Nice To Haves

• Experience leading Microsoft Entra or Microsoft 365 governance remediation from discovery through implementation and handover.
• Demonstrated success reducing unnecessary licensing, improving license assignment accuracy, and introducing automated joiner, mover, and leaver processes.
• Experience rationalizing low-use or poorly governed services and reducing unmanaged OneDrive usage through clear policy, migration, and decommissioning plans.
• Knowledge of Microsoft Defender, Microsoft Purview, Azure Monitor, Microsoft Sentinel, or comparable security and compliance tooling.
• Experience translating historic ad hoc IT requests into approved patterns, service catalogs, standards, and change processes.
• Relevant Microsoft, identity, security, or cloud certifications.

Responsibilities

• Review the current tenant configuration, administrative model, licensing position, integrations, service usage, and historical requests.
• Discover existing ownership and appropriate guardrails, and prevent low current utilization from leading to further unmanaged adoption.
• Define a prioritized remediation plan based on security risk, operational impact, and business value.
• Implement approved changes and validate outcomes.
• Communicate risks, dependencies, and decisions clearly.
• Work with Security on SIEM visibility, logging, detections, and alerting.
• Document the target state and train Operations and Engineering teams to maintain it.
