Infrastructure & Cloud Systems Engineer

About the role

Sargent & Lundy is seeking a skilled Infrastructure & Cloud Systems Engineer to join our dynamic team. This role requires a deep understanding of both on-premises data center infrastructure and cloud environments, with a focus on reliability, performance, and security.

Responsibilities

• Administer and optimize physical and virtual server environments across on-premises data centers, including resource allocation, capacity planning, and lifecycle management.

• Manage VMware vSphere/vCenter environments — including ESXi host configuration, VM provisioning, cluster management, DRS/HA policies, and license optimization to control spend and maximize utilization.

• Perform regular hardware health monitoring, firmware patching, and hardware lifecycle tracking in coordination with vendor support.

• Own storage administration across SAN/NAS environments — LUN provisioning, volume management, performance tuning, and capacity forecasting.

• Maintain network fabric within the data center, including VLAN configuration, switching, and integration with enterprise routing and firewall infrastructure.

• Drive disaster recovery and business continuity for on-premises systems — design, execute, and document DR/failover tests on a defined schedule; validate RTO/RPO targets and remediate gaps.

• Design, deploy, and maintain Azure infrastructure — compute, networking, storage, identity, and platform services — in alignment with architecture standards and security baselines.

• Manage Azure AD/Entra ID, RBAC, Conditional Access, and identity governance for both cloud and hybrid environments.

• Implement and maintain cloud cost governance — right-sizing, reserved instance strategy, tagging hygiene, and license optimization across cloud resource pools.

• Build and maintain Infrastructure as Code using Terraform, ARM templates, or Bicep to ensure consistent, auditable, and repeatable provisioning.

• Develop and manage CI/CD pipelines for infrastructure deployment using Azure DevOps or GitHub Actions.

• Administer HPE compute platforms (ProLiant, Synergy, BladeSystem), HPE OneView, and iLO administration.

• Manage HPE storage platforms — HPE 3PAR, Nimble Storage, or MSA — including LUN management, replication, and performance tuning.

• Leverage HPE InfoSight and CloudPhysics (or equivalent HPE AI Ops tools) for predictive analytics, anomaly detection, and workload optimization across the HP stack.

• Coordinate with HPE support and field engineers for hardware break/fix, parts replacement, and proactive maintenance under active support contracts.

• Monitor and respond to infrastructure alerts across on-prem and cloud using centralized observability platforms; drive incident resolution and root cause analysis.

• Automate operational workflows — patching, provisioning, remediation, compliance reporting — using PowerShell, Ansible, Python, or Azure CLI.

• Implement and enforce security controls: encryption at rest and in transit, vulnerability remediation, firewall policy management, logging, audit trails, and compliance with organizational and regulatory requirements.

• Partner with security, development, and IT operations teams to deliver resilient, scalable hybrid solutions and serve as an escalation point for complex infrastructure issues.

• Develop and maintain runbooks, standard operating procedures, architecture documentation, and operational playbooks.

• Contribute to infrastructure roadmaps and standards; proactively identify opportunities to reduce technical debt, improve efficiency, and increase platform maturity.

• Participate in on-call rotation and after-hours maintenance windows as required.

Qualifications

• Bachelor’s degree in Computer Science, Information Technology, Engineering, or a related field — or an equivalent combination of education and demonstrated hands-on experience.

• 8+ years of hands-on experience in infrastructure engineering, systems administration, or cloud engineering in enterprise production environments.

• Deep expertise in VMware vSphere/vCenter — cluster administration, resource pool management, DRS/HA, vSAN, and license optimization.

• 5+ years with Microsoft Azure — Compute, Networking, Storage, Entra ID, Monitor, Key Vault, and hybrid connectivity (ExpressRoute, VPN).

• Proven experience designing and executing disaster recovery plans and failover tests; familiarity with replication technologies (Zerto, Azure Site Recovery, Veeam, or equivalent).

• Hands-on experience with HPE compute platforms (ProLiant, Synergy, BladeSystem), HPE OneView, and iLO administration.

• Experience with HPE storage platforms — HPE 3PAR, Nimble Storage, or MSA — including LUN management, replication, and performance tuning.

• Familiarity with HPE Aruba data center networking and HPE InfoSight or similar AI Ops tooling.

• Strong command of Microsoft server platforms — Active Directory, Windows Server, DNS/DHCP, IIS, file services.

• Hands-on experience with Infrastructure as Code (Terraform, ARM/Bicep) and configuration management (Ansible, DSC, or equivalent).

• Proficiency in scripting and automation: PowerShell, Python, Azure CLI, or Bash.

• Experience with SAN/NAS administration and enterprise storage management.

• Solid networking fundamentals: TCP/IP, DNS, VPN, firewalls, load balancing, and data center switching/routing.

• Familiarity with change management, incident management, and ITSM processes (ServiceNow or equivalent).

• Strong communicator with the ability to document clearly and collaborate across technical and non-technical stakeholders.
