ICS/SCADA
Engineer to support a Department of Defense customer's operational technology (OT) and industrial control systems work. The environment combines real field hardware with virtualized and simulated OT components that reflect real-world industrial control systems. You'll help design, configure, and secure those systems, and help find and fix the weaknesses in them. This role suits a hands-on problem solver who likes working across hardware, software, and networks on a small, fast-moving team. What you'll do Design, build, and maintain physical and virtual OT/ICS environments that mirror power, water, and other critical infrastructure systems. Research threats to PLCs, RTUs, IEDs, and
SCADA/HMI
systems, and develop and test mitigations for the vulnerabilities you find. Plan and run tests, collect and analyze data, and write up the approach, results, and recommendations. Prototype new OT/ICS capabilities and integrate them into existing environments to keep them current and realistic. Work alongside government, industry, and utility partners on configuration, testing, and shared research. Travel occasionally to partner sites and ranges (up to about 25%). What you bring At least 5 years of hands-on experience or academic research in
ICS/SCADA, OT
networking, or critical infrastructure security. Programming experience in C, C++, Python, or Java. Experience programming and configuring PLC, RTU, and IED hardware, and building or supporting
SCADA/HMI
systems. Working knowledge of industrial protocols such as DNP3, Modbus, IEC 60870-5-101/104, IEC 61850, EtherNet/IP, SEL, and OPC. Comfort with Windows, Linux, and real-time operating systems such as VxWorks. Experience performing threat and vulnerability analysis on
ICS/SCADA
environments. Ability to read and update technical drawings, schematics, and one-line diagrams in CAD tools. Experience virtualizing OT components to model real-world infrastructure. Nice to have Operational time in electric power, water, energy, transportation, or manufacturing environments. A master's degree in a related field. Education Bachelor's degree in Electrical or Computer Engineering, Computer Science, or Industrial Engineering (an ICS/SCADA or robotics focus is a plus). Other STEM degrees paired with relevant experience will be considered. How you'll work You set your own plan, pick up new hardware and tools quickly, and stay steady when deadlines get tight. You're equally comfortable on a team effort or owning a project yourself. Requirements U.S. citizenship
