ppAs an OT Expert, you will serve as the subject matter expert (SME) for OT cyber visibility, architecture, and governance. You’ll lead asset discovery, segmentation strategy, and integration of monitoring platforms across complex ICSe environments. This is a client-facing role, engaging with multiple customers to enhance their OT security posture and demonstrate the business value of risk reduction. /p pYou’ll work closely with infrastructure, compliance, product, and field teams to implement security best practices aligned to IEC 62443, NIST CSF, and CPwE frameworks. /p pKey Responsibilities /p ul liLead the deployment, configuration, and tuning of OT security platforms across customer ICSe environments. /li liSupport TCSM teams with value delivery, operationalizing OT visibility solutions within the context of customer business priorities. /li liDrive asset inventory accuracy, passive discovery strategies, and enriched contextual mapping for PLCs, HMIs, and SCADA systems. /li liAlign segmentation and network architecture to industry standards such as IEC 62443, CPwE, and NIST CSF 2.0. /li liPartner with internal and client-side IT/OT teams to facilitate patching, firmware updates, and configuration hardening across industrial assets. /li liProvide architectural input and hands-on guidance on OT threat detection, alert tuning, and event correlation via integration with SIEM and SOC tools. /li liBuild dashboards, KPIs, and reports showcasing asset risk, segmentation posture, and threat trends across OT networks. /li liLead OT-focused workshops, risk reviews, and client advisory sessions to promote awareness and maturity of ICSe security programs. /li liContinuously assess the effectiveness of OT tools and advocate improvements via vendor and internal engineering collaboration.



/li liSupport compliance efforts (e.g., NERC CIP, ISA/IEC 62443, NIST 800-82) by generating asset visibility reports and vulnerability context. /li liCollaborate with stakeholders across multiple accounts to identify OT security gaps and design strategic roadmaps for improvement. /li /ul pbQualifications /b /p ul li8+ years in OT cybersecurity, ICSe/SCADA security, or industrial IT. /li liExperience with OT/ICS security platforms such as Armis, Claroty, Nozomi, Ordr, or similar. /li liFamiliarity with industrial protocols (e.g., Modbus, OPC, DNP3, Profinet), ICSe devices (PLCs, HMIs), and vendor ecosystems (Rockwell, Siemens, Schneider, etc.). /li liStrong understanding of network segmentation, passive monitoring, and ICSe risk management frameworks (IEC 62443, NIST CSF). /li liHands-on experience working in or securing OT/ICS environments in manufacturing, utilities, or critical infrastructure. /li liCapable of working in U.S. Federal/Government-compliant environments (U.S. Citizen or equivalent clearance eligible). /li liUnderstanding of CVEs/CVSS scoring and OT vulnerability prioritization. /li liExperience with scripting/automation (Python, Bash, PowerShell) and REST APIs for tool integration. /li liStrong communication skills with the ability to simplify complex ICSe risks for technical and non-technical stakeholders. /li /ul pPreferred Qualifications /p ul liCertifications such as GICSP, GRID, ISA/IEC 62443, CISSP, or OSCP. /li liExperience with patch management in OT environments. /li liFamiliarity with integrating OT visibility tools with SIEM (e.g., Splunk, QRadar), CMDB, or SOC workflows. /li liExperience with RBVM or vulnerability tracking in ICSe (Qualys, Tenable.ot, Rapid7, etc.). /li liExposure to AppSec concepts and toolchains (optional, for hybrid environments). /li /ul /p #J-18808-Ljbffr
