TL;DR

Join our visionary team as an OT Security Engineer and shape the future of OT/IoT cybersecurity by designing resilient architectures for industrial control systems and driving vulnerability management strategies. You will develop secure designs for ICS, SCADA, PLCs, and HMIs while ensuring compliance with standards like ISA/IEC 62443 and NIST 800-82. Your role involves conducting risk assessments, leading vulnerability analyses, and integrating threat intelligence into workflows. Collaborate closely with engineering, operations, and IT teams to embed security throughout the system lifecycle, evaluate emerging technologies, and provide training on best practices. Ideal candidates have deep expertise in OT/IoT security architecture, 7–10 years of relevant experience, knowledge of ICS protocols (Modbus, OPC, Ethernet/IP), familiarity with Armis, Dragos, Claroty, and certifications like GICSP or CISSP.
