What you need

  • 4–7 years total experience, with at least 2–3 years in OT security, ICS/SCADA security, or critical infrastructure environments
  • Solid understanding of industrial protocols (Modbus, BACnet, DNP3, OPC, etc.)
  • Knowledge of OT network architectures and segmentation
  • Experience with BMS, EPMS, PLCs, and industrial controllers
  • Familiarity with OT asset discovery and monitoring solutions
  • Experience in hardening OT systems (Windows, Linux, HMIs, controllers)

Nice to have

  • Certifications such as GICSP, GRID, ISA/IEC 62443 Cybersecurity Expert/Certificate, CCNA, or similar
  • Experience in data centres, utilities, industrial automation, mining, manufacturing, or other critical infrastructure sectors
  • Prior exposure to hyperscale environments or large-scale multi-site OT systems.

Worth weighing

  • No salary listed
  • The role involves a hands-on engineering focus, which may not suit those looking for a purely strategic position.
