## Description

Experteer Overview In this role you will design, secure and sustain control systems and OT infrastructures for essential DOE and energy-sector operations, spanning nuclear facilities, accelerator systems, and experimental platforms. You will work at the intersection of OT engineering, cybersecurity, facility operations, and research programs to deliver resilient, well-architected systems aligned with NIST and DOE requirements. You will shape architectures, security, and sustainment practices that enable mission-critical operations and 24/7 readiness. This is an opportunity to apply systems engineering in a high-consequence, real-world impact environment. Compensation / Benefits * Systems Architecture & Design for secure, resilient OT/industrial control environments * Deploy and operate complex OT/ICS infrastructure across Windows/Linux servers, virtualization, storage, and related services * Manage OT security and DOE compliance controls, vulnerability management, patching, and secure baselines * Drive automation and monitoring using PowerShell, Python, Ansible; deploy observability platforms (Splunk, Elastic/Grafana, SolarWinds, Nozomi/Claroty) * Create inventories, diagrams, SOPs and precise configuration documentation to sustain long-term reliability Tasks * 5-10+ years as a Systems Engineer or Architect * 3+ years supporting OT/ICS or critical infrastructure * Strong Windows/Linux administration, virtualization, and storage experience * Background with SCADA/ICS architectures, HMIs, engineering workstations, and historians * Familiarity with NIST cybersecurity frameworks * Hands-on configuration management, patching, imaging, and lifecycle processes * Experience supporting operational environments (energy, nuclear, accelerator, national lab, or 24/7 mission systems) * Ability to collaborate across engineering, cybersecurity, operations, and research groups Key requirements *
