Senior Infrastructure Engineer – Active Directory – hybrid | Revel IT

Our Goal

Treat our consultants and clients the way we would like others to treat us! Interested in joining our team? Check out the opportunity below and apply today!

Our Columbus, Ohio client is growing their infrastructure team and has a contract-to-hire opportunity for a Senior Infrastructure Engineer – Active Directory who will design and operate Active Directory and hybrid identity, partner on cloud identity patterns, and be the person both engineers and leadership rely on when authentication is on the line.

On‑site expectations are on‑site Monday through Thursday and remote on Fridays.

• Design, implement, and maintain Active Directory (sites, replication, OU/GPO models, trust relationships) and closely coupled services (DNS, DHCP) with clear standards and change control.
• Implement and evolve hybrid identity patterns (for example Microsoft Entra  / Connect, hybrid join, federation concepts, conditional access alignment) in partnership with security and cloud teams.
• Enforce identity, privileged access, and Group Policy practices that meet audit and risk expectations; support certificate and authentication models where they touch AD.
• Lead recovery and forest/domain health scenarios with documented playbooks and measurable recovery objectives.

• Design and maintain hybrid infrastructure spanning on‑premises and cloud platforms, with identity as the integration layer across workloads.
• Operate and support VMware ESXi and vCenter environments that host directory‑related and dependent workloads.
• Support enterprise storage (SAN/NAS) for performance, redundancy, and recoverability of identity and infrastructure services.
• Collaborate with the Citrix team to ensure AD authentication, GPO policies, and session delivery integration are correctly configured—you influence identity behavior here, not platform administration.
• Manage enterprise backup and recovery for critical identity and infrastructure targets; validate restores and retention against policy.
• Perform routine maintenance, upgrades, and patching across servers, virtualization, and cloud‑connected systems with minimal customer impact.

• Evaluate and optimize resource utilization across on‑premises and cloud platforms.
• Recommend and implement cost‑aware strategies for compute, storage, and cloud consumption.
• Analyze trends and propose improvements that increase service efficiency and availability.

• Drive security hardening across AD, servers, virtualization, and connected cloud services—including Tiered Administration (PAW model), LAPS deployment, and Microsoft Defender for Identity for real‑time threat detection across the directory.
• Monitor and remediate vulnerabilities through patching, configuration management, and risk mitigation aligned to SLAs.
• Maintain compliance with corporate policies, audit requirements, and industry standards.

• Serve as a senior escalation point for infrastructure incidents and problems with an identity‑centric lens.
• Lead technical root cause analysis and implement durable corrective actions.
• Mentor junior engineers and contribute to infrastructure engineering standards and patterns.
• Participate in planning and executing major projects, migrations, and deployments.

• Monitor performance across servers, virtualization, storage, and cloud services; conduct capacity planning for compute, storage, and network resources.
• Implement monitoring and alerting for proactive detection of directory and platform issues.
• Create and maintain technical documentation, diagrams, build guides, SOPs, and compliance evidence; report on health, performance, and posture.

• Partner with application, security, cloud, and networking teams for end‑to‑end solutions.
• Work with business stakeholders to translate requirements into scalable, supportable designs.
• Communicate clearly to technical and non-technical audiences.
