ICS/SCADA Engineer at G6 Cyber Solutions in San Antonio, TX

About the role

G6 Cyber Solutions is looking for an 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
