Senior Infrastructure & Cloud Engineer (IaaS)

Overview

Looking to make a difference and help modernize critical government missions? Join Acuity's team supporting the U.S. Department of State. As a Senior Infrastructure & Cloud Engineer (IaaS), you will provide hands-on engineering support for mission-critical data center, virtualization, compute, storage, hybrid-cloud, and globally distributed infrastructure. This role is deeply focused on enterprise VMware environments, Windows Server and Linux platforms, hyperconverged infrastructure (HCI), SAN/NAS storage, and the resilient infrastructure services that support Department of State operations worldwide.

Working closely with the Cloud Technical Lead, Cloud Engineers, Automation Engineers, Network Engineers, Cybersecurity teams, and government stakeholders, you will provide Tier 3 infrastructure engineering and troubleshooting, support infrastructure lifecycle modernization, and ensure the availability, security, resiliency, capacity, and performance of enterprise systems across domestic, overseas, on-premises, and cloud environments.

• Strong hands-on experience administering and troubleshooting both Windows Server and Linux operating systems in enterprise environments.
• Experience supporting enterprise compute and hyperconverged infrastructure (HCI) platforms in highly available production environments.
• Experience administering enterprise SAN and/or NAS storage and supporting storage integration with virtualized infrastructure.
• Demonstrated Tier 3 infrastructure troubleshooting and root cause analysis experience across compute, virtualization, storage, operating systems, and related infrastructure services.
• Experience designing, implementing, or supporting high availability, disaster recovery, backup, resiliency, and business-continuity solutions.
• Experience managing infrastructure lifecycle activities, including upgrades, migrations, technology refresh, and EOL/EOS remediation.
• Experience with enterprise infrastructure monitoring, capacity management, performance analysis, and availability management.
• Hands-on scripting or automation experience using PowerShell, Bash, Python, Ansible, Terraform, or similar technologies.
• Experience supporting at least one major cloud service provider (AWS or Microsoft Azure) and hybrid-cloud integration with enterprise on-premises infrastructure.
• Experience working within ITSM processes and disciplines, including change management, incident management, problem management, and root cause analysis.
• Experience implementing federal security and configuration compliance requirements, such as NIST RMF, NIST SP 800-53, FISMA, STIGs, vulnerability remediation, system hardening, or comparable federal standards.
• Strong analytical, troubleshooting, documentation, communication, and cross-team collaboration skills.

Preferred Qualifications

• Experience supporting globally distributed, overseas, or remote enterprise infrastructure environments, particularly environments requiring coordination across geographically dispersed teams.
• VMware Certified Professional (VCP) or equivalent VMware certification.
