Job Description

We are seeking an OT Network Engineer to contribute to the development of an industrial automation and security platform with advanced OT network discovery, device fingerprinting, real-time tracking, and security compliance features . The ideal candidate will have expertise in network scanning, industrial protocols (SNMP, LLDP, ARP), Zero Trust security, IEC 62443 compliance, and PLC inventory management . This role requires hands-on experience in building scalable, secure, and AI-driven OT networking solutions integrated into the platform. Key Responsibilities: OT Network Discovery & Device Fingerprinting Develop and integrate automated network scanning for industrial assets into the platform. Implement passive & active network scanning using SNMP, LLDP, ARP, and industrial protocols. Design and optimize device fingerprinting to classify OT devices (PLCs, SCADA nodes, IIoT gateways, sensors) based on manufacturer, model, firmware, and protocol stack. Enable real-time endpoint tracking and automated asset registration within the platform. 2. Industrial Network Security & Compliance (IEC 62443, Zero Trust) Implement IEC 62443-based security frameworks within the platform to ensure OT network compliance. Integrate Zero Trust security models for industrial endpoints and control networks. Work on network segmentation strategies for isolating critical industrial systems within the platform. Design and develop anomaly detection features for unauthorized device behaviors using AI-based security analytics. 3. SCADA-Integrated Asset Management & Monitoring Contribute to the development of a SCADA-integrated asset inventory system for industrial environments. Develop a real-time monitoring engine for tracking PLC instances, network ports, and communication health. Optimize SCADA-to-OT data flows for improved visibility and control. Design SCADA security monitoring dashboards for operational visibility and threat detection. 4. OT Network Simulation & Testing Framework Develop a virtualized OT network environment for testing protocol translations and device communications. Simulate SCADA-to-PLC interactions within a cloud-based or hybrid testing framework. Create automated test cases for evaluating platform performance in large-scale OT environments. 5. AI-Driven Security & Network Optimization Contribute to AI-powered security heuristics for intrusion detection, anomaly recognition, and behavioral analysis. – Strongly Preferred Design real-time correlation engines to map network security events to operational risk indicators. Work with data scientists to integrate machine learning models for predictive network failure analysis. Required Skills & Qualifications: Networking & Industrial Protocols: Expertise in SNMP, LLDP, ARP-based discovery and industrial networking standards. Deep understanding of SCADA, PLC, DCS, and IIoT network architectures. Strong knowledge of Modbus TCP/IP, OPC-UA, EtherNet/IP, PROFINET. Security & Compliance: In-depth knowledge of IEC 62443, Zero Trust Architecture (ZTA), and industrial cybersecurity. Experience in firewall configurations, network segmentation, and encrypted communications (TLS 1.3, AES-256). Understanding of SIEM integration and OT security monitoring tools (Claroty, Nozomi, Dragos, CyberX). Platform Development & Integration: Experience in building scalable network discovery and security platforms for industrial automation. Familiarity with cloud-based OT security solutions (Azure Defender for IoT, AWS IoT Device Defender). Ability to work with RESTful APIs, MQTT, Kafka, and real-time event processing frameworks. Tools & Technologies: Network Security & Monitoring: Wireshark, Nmap, Zeek, Snort, Suricata. OT Security Platforms: Claroty, Nozomi Networks, Dragos, CyberX. Cloud & Edge Security: Azure IoT Hub, AWS IoT Core, Google Cloud IoT. PLC & SCADA Systems: Siemens, Rockwell, ABB, Schneider Electric, GE. Cloud & Edge Security: Azure Defender for IoT, AWS IoT Device Defender. Show more Show less
