Job description

Senior Infrastructure Engineer

Location: Fully Remote | Eastern Time Business Hours

Employment Type: 12-Month Contract, with Potential for Extension

Compensation: ~$67-75/hr (Final compensation will be dependent on experience and skillset level)

ABOUT THE ROLE

Our client, a large utility company, is hiring a Senior Infrastructure Engineer to support its Data Center Automation (DCA) initiative.

The team uses Ansible and Terraform to automate infrastructure deployments across on-premises and cloud environments. Your responsibility will be to ensure the underlying infrastructure is configured, accessible, and ready for those deployments.

You'll troubleshoot server connectivity, firewall restrictions, authentication failures, and access permissions. You'll also coordinate with networking, security, and infrastructure teams to resolve issues and work through the approvals required in a regulated enterprise environment.

This is a hands-on infrastructure administration role, not a position focused on writing automation code.

WHAT YOU'LL DO

• Administer and troubleshoot Linux and/or Windows server infrastructure across physical, virtual, and cloud environments.
• Investigate connectivity issues that prevent automation platforms from communicating with servers and infrastructure systems.
• Diagnose network, DNS, firewall, routing, and authentication issues to identify the source of deployment failures.
• Submit and coordinate firewall rule changes, network access requests, and security approvals.
• Configure and troubleshoot user permissions, service accounts, Role-Based Access Control (RBAC), and authentication methods.
• Work with identity and access management (IAM) and security teams to resolve authorization and access restrictions.
• Support infrastructure readiness for deployments managed through Ansible and Terraform, without being responsible for developing the automation code.
• Troubleshoot server configurations, operating system issues, and VMware or similar virtualization environments.
• Follow enterprise change-management and security procedures when making infrastructure changes.
• Partner with automation engineers, server administrators, network engineers, and security teams to resolve deployment blockers.
• Document troubleshooting steps, infrastructure changes, and resolutions.
• Share infrastructure knowledge with junior engineers and participate in the team's agile workflows.

WHAT YOU BRING

• 7-10+ years of hands-on experience in infrastructure engineering, systems administration, server engineering, or network engineering.
• Experience administering and troubleshooting enterprise Linux and/or Windows servers.
• Working knowledge of TCP/IP networking, DNS, routing, connectivity troubleshooting, and firewall concepts.
• Experience investigating firewall restrictions and coordinating firewall rule requests or network access changes.
• Experience managing user accounts, service accounts, permissions, and authentication configurations.
• Familiarity with RBAC, IAM, Active Directory, LDAP, SSH, or similar access-management technologies.
• Understanding of infrastructure security controls and enterprise change-management processes.
• Experience troubleshooting production infrastructure issues and working with multiple technical teams to resolve them.
• Experience with VMware, Hyper-V, or comparable virtualization platforms.
• Ability to independently investigate technical issues, identify dependencies, and coordinate their resolution.

NICE TO HAVE

• Familiarity with Ansible, Terraform, or other infrastructure automation tools.
• Experience supporting automation platforms or troubleshooting infrastructure issues affecting automated deployments.
• Experience working in a utility, financial services, healthcare, government, or another regulated environment.
• Experience supporting infrastructure across both on-premises data centers and cloud environments.
• Experience mentoring or supporting junior infrastructure or automation engineers.

This position is suited to an infrastructure engineer who enjoys diagnosing why systems cannot communicate, identifying where access is restricted, and coordinating the changes needed to get deployments working.
