OT Security Engineer

We are seeking a highly experienced OT Security Engineer with deep expertise in industrial cybersecurity, IoT security, and edge technologies to support secure IT–OT convergence initiatives across manufacturing and industrial environments.

• Design and implement OT cybersecurity frameworks aligned with IEC 62443 and NIST SP 800-82 standards


• Assess, secure, and optimize Industrial Control Systems (ICS) including PLCs, SCADA, RTUs, and MES platforms


• Conduct comprehensive OT risk assessments, vulnerability management, and compliance evaluations


• Implement and manage OT SOC/SIEM solutions such as Splunk, Microsoft Sentinel, and IBM QRadar


• Deploy and operate OT threat detection and monitoring solutions (e.g., Nozomi, Claroty, Tenable)


• Design and secure IoT platforms including Azure IoT, AWS IoT, and AWS Greengrass


• Architect and manage edge data pipelines for data collection, filtering, processing, and secure cloud transmission


• Define and execute incident response strategies tailored for OT environments


• Manage the end-to-end lifecycle of OT/IoT devices (PLCs, RTUs, HMIs, sensors), including:
  
  
  
  • Device provisioning and onboarding
  
  
  • PKI and certificate lifecycle management
  
  
  • OTA updates and patch management
  
  


• Design, deploy, and manage secure edge infrastructure, ensuring reliable data handling and secure communications


• Implement Zero Trust principles in OT environments, including device identity (PKI), micro-segmentation, and secure remote access


• Operate IoT and edge orchestration platforms such as Kubernetes and IoT Edge


• Manage edge connectivity (5G/LTE, SD-WAN, LAN/WAN integration)


• Oversee edge nodes, clusters, and OS/container platforms (Linux, Windows IoT, Kubernetes)


• Ensure resilience and disaster recovery through geo-redundancy and failover strategies


• Support edge observability and telemetry pipelines (Kafka, streaming platforms, time-series databases)


• Optimize performance, power consumption, and sustainability of edge deployments

• Strong hands-on experience in plant OT environments (PLC, SCADA, RTU, MES)


• Expertise in IoT security and edge architecture implementation


• Solid understanding of device identity, PKI, and secure communication protocols


• Experience with IT–OT network segmentation and Zero Trust architectures


• Familiarity with AI/ML-based anomaly detection in industrial environments (preferred)


• Strong analytical, problem-solving, and operational ownership mindset


• Excellent communication and stakeholder management skills


• Ability to collaborate effectively with CISOs, plant teams, IT, and SOC teams


• Proven track record in leading security assessments and driving OT security initiatives

• Minimum 8+ years of experience in OT cybersecurity / industrial security


• Proven experience in manufacturing, energy, or similar industrial sectors
