About the role
We are seeking a highly experienced and technically proficient Senior Systems Engineer to manage, optimize, and secure critical enterprise infrastructure at the Dept of State in Washington, DC. The ideal candidate will be a hands-on expert in Windows Server, Active Directory, and virtualization technologies, with a strong focus on automation and cloud adoption. This role requires deep technical troubleshooting skills and the ability to work in a secure, on-site environment.
What You'll Do
- Own Windows Server/Active Directory (AD) Services (GPO, DNS/DHCP, OU design, patching, monitoring) across production enclaves, ensuring high availability and optimal performance.
- Design, implement, and manage enterprise virtualization platforms, primarily using VMware ESXi, for maximum efficiency and resource utilization.
- Automate infrastructure deployment, configuration, and maintenance at scale using PowerShell and other scripting languages (e.g., Python), focusing on IaC (Infrastructure as Code) principles.
- Architect, deploy, and manage Public Key Infrastructure (PKI) solutions and oversee certificate/TLS lifecycle management across the enterprise.
- Perform complex, end-to-end troubleshooting of infrastructure issues, covering networking (TCP/IP, routing, load balancing), identity (Kerberos/LDAP), and application integration.
- Document runbooks, standard operating procedures (SOPs), and change procedures; participate in scheduled change windows and on-call rotation.
- Contribute to cloud strategy and migration efforts by providing technical expertise for AWS and/or Azure platform integration.
- Ensure systems adhere to stringent security requirements (e.g., STIG/RMF/NIST), especially within federal or classified environments.
What You Bring ( Required Qualifications)
- Active Top Secret with SCI (active or cross-over-eligible).
- Bachelor's in computer science, Information Technology, or related field — or equivalent practical experience.
- 10+ years Server administration
- Proficiency in PowerShell for complex administration, reporting, and automation.
- Extensive experience with virtualization platforms (ESXi, Hyper-V, or KVM), including Horizon Remote Assistance.
- Experience with VDI deployments.
- Hands-on experience with Solarwinds for enterprise IT infrastructure and environment monitoring.
- Experience with Active Directory in production environments.
We Value (Differentiators)
- Experience managing and configuring MS Exchange environments.
- Deep understanding of networking fundamentals (TCP/IP, DNS, DHCP, routing protocols) and experience with load balancers (e.g., F5/NetScaler).
- Proven experience in designing and managing PKI and handling the entire certificate lifecycle.
- Excellent written and verbal communication skills, with a proven ability to document complex systems.
- Background in AWS and/or Azure infrastructure, services, and best practices.
- Familiarity with security compliance frameworks and tools for federal/classified environments (STIG, RMF, NIST).
- Experience with enterprise monitoring solutions (e.g., SCOM, Splunk, health sets) is a plus.
- Exposure to Microsoft 365 (M365) technologies, including Hybrid/M365 touchpoints (e.g., Modern Auth, EOP/Defender).
