Job Title: OT Network Traffic Analyst – Anomaly Detection Specialist
Job Summary:
We are seeking a skilled OT Network Traffic Analyst with deep expertise in Operational
Technology (OT) communication protocols to join our cross-functional security and ML team.
The ideal candidate will be responsible for intercepting and analyzing OT network traffic,
identifying potential anomalies, and contributing to the development of cutting-edge anomaly
detection solutions — even across proprietary and undocumented protocols.
This is a hands-on role requiring both technical proficiency in network traffic inspection and the
ability to collaborate with machine learning engineers and cybersecurity experts.
Key Responsibilities:
• Intercept, monitor, and analyze traffic from OT/ICS networks in real-time and from
historical captures.
• Perform protocol-level inspection across standard (e.g., Modbus, DNP3, OPC-UA, IEC
61850) and proprietary OT communication protocols.
• Reverse engineer undocumented or proprietary OT protocols where necessary.
• Identify and flag anomalous behavior or patterns in the traffic, correlating with known
attack vectors or operational deviations.
• Collaborate with ML engineers to define features and data inputs for anomaly detection
models.
• Contribute domain expertise in OT to refine, validate, and test detection algorithms.
• Assist in setting up testbeds and simulations to emulate OT environments and collect
relevant traffic data.
• Document findings and create actionable reports for both technical and non-technical
stakeholders.
• Stay current with advancements in OT threat intelligence and anomaly detection research.
Required Qualifications:
• Bachelor's or Master's degree in Computer Science, Electrical Engineering, Cybersecurity,
or a related field.
• 3+ years of experience working in OT/ICS settings.
• Deep understanding of OT communication protocols (e.g., Modbus, BACnet, PROFINET,
OPC, etc.), including ability to analyze r
