Engineering System Administrator, Principal

Job Summary

Are you energized by solving complex engineering challenges that directly support national security, energy reliability, and scientific innovation? We’re looking for a Systems Engineer / Systems Architect who thrives in mission‑critical environments and is ready to take on a role where their work truly makes a difference.

In this position, you’ll design, secure, and sustain the control systems and OT infrastructures that keep essential DOE and energy‑sector operations running—spanning nuclear facilities, accelerator systems, experimental platforms, and site‑wide operational technologies.

You’ll work at the intersection of OT engineering, cybersecurity, facility operations, and research programs to deliver resilient, well‑architected systems aligned with NIST frameworks and DOE requirements. If you enjoy systems engineering with real‑world impact, this is a unique opportunity.

What You’ll Do

Systems Architecture & Design: You craft secure, resilient system architectures built for high‑consequence OT and industrial control environments. Your designs follow industry-leading frameworks—including NIST 800‑82, NIST 800‑53/171, and ISA/IEC 62443—and support a wide range of mission‑critical systems such as SCADA, PLC/DCS, building automation, and power distribution. You define architectures that deliver deterministic performance, high availability, and fault tolerance, all while maintaining rigorous configuration baselines, lifecycle documentation, and design records.

Systems Engineering, Deployment & Operations: You engineer, deploy, and operate complex infrastructure across Windows/Linux servers, virtualization platforms, clustered systems, and enterprise storage. Your work integrates OT and ICS environments with core services for authentication, monitoring, patching, and secure remote access. You support SCADA/HMI servers, historians, and engineering workstations, ensuring reliable data movement between OT and enterprise/DMZ networks. You also develop inventories, diagrams, SOPs, and precise configuration documentation to sustain long-term system reliability.

OT Security & DOE Compliance: You implement NIST‑aligned security controls and DOE cybersecurity requirements across operational technology environments. Your role supports vulnerability management, patching programs, and secure baseline maintenance. You participate in cyber and operational readiness assessments and integrate systems with enterprise monitoring, logging, and detection platforms. You safeguard OT access by managing privileged workflows, vendor connectivity, and secure identity operations.

Automation, Monitoring & Sustainment: You drive safe and effective automation using PowerShell, Python, Ansible, and similar tooling. You deploy and manage monitoring and observability platforms such as Splunk, Elastic/Grafana, SolarWinds, and Nozomi/Claroty. You perform root‑cause analyses, support cyber and operational incident response, and continually refine system reliability and performance across mission‑critical operations.

We'd Love to Hear from Candidates With
• 5–10+ years as a Systems Engineer or Architect, including 3+ years supporting OT/ICS or critical infrastructure
• Strong experience with Windows/Linux administration, virtualization (VMware, Hyper‑V, KVM), and storage systems
• Background with SCADA/ICS architectures, HMIs, engineering workstations, and historians
• Working knowledge of NIST cybersecurity frameworks
• Hands‑on experience with configuration management, patching, imaging, and lifecycle processes
• Experience supporting operational environments such as energy, nuclear, accelerator, national lab, or 24/7 mission systems
• Ability to collaborate seamlessly across engineering, cybersecurity, operations, and research groups

A Successful Candidate Also Brings:
• Certifications: CISSP, Security+, GICSP, Microsoft/Linux engineering certs, VMware VCP, Red Hat, ISA/IEC 62443
• Experience in secure or high‑hazard environments (nuclear, accelerator, etc.)
• Familiarity with OT monitoring tools (Nozomi, Claroty, Dragos) and SIEM platforms
• Background designing resilient architectures for scientific or experimental workloads
• Experience with cyber assessments and configuration management processes

In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States and to complete the required employment eligibility verification form upon hire.

This position will require a pre­-employment background check and a pre-employment drug test.
