Job Description

Revolutional delivers advanced technology solutions and mission support to federal agencies across civilian, health, and national security environments. We apply modern capabilities, including AI/ML, cloud, cybersecurity, and IT modernization to solve complex challenges, enable faster and more secure operations, and drive measurable mission outcomes.

We are redefining how federal technology gets built and delivered by operating with a product mindset, prioritizing speed, ownership, and execution over bureaucracy.

Description

Title: Senior Systems Engineer

Location: Washington, DC (Onsite)

Terms: Full-time

Salary: 150k - 180k DOE

Clearance: Top Secret with SCI eligibility - Required

Travel: <10%

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).
