  • Produce clear and actionable security reports for technical teams and leadership.
  • Collaborate with engineering and plant operations teams to onboard new OT assets and maintain detection coverage.
  • Contribute to OT security policies, procedures, and playbooks.
  • Mentor junior analysts and support team capability development.
Requirements

  • Experience with SIEM platforms and log correlation in hybrid IT/OT environments.
  • Knowledge of network segmentation principles and OT-specific security architectures.
  • Familiarity with IEC 62443 and NIST SP 800-82.
  • Certifications preferred: GICSP, Nozomi Networks Certified Expert, CSSA, or equivalent.
