Your Responsibilities

• You’ll act as the primary security administrator for all OT and SCADA services, ensuring secure architectures, monitoring, and operational readiness.

• In this role, you’ll develop and maintain SCADA-specific SOPs, incident response runbooks, and operational security controls.

• You’ll conduct regular risk assessments and vulnerability analyses across SCADA applications and connected IT systems.

• You’ll provide hands-on guidance and consultation to SCADA teams, aligning operational goals with security best practices.

• You’ll contribute to security project work, including legacy system risk mitigation, decommissioning, or migration initiatives.

• You’ll support broader cybersecurity operations, including threat investigation, patching, and security control administration.

Skills and Qualifications

• 4+ years of experience designing, implementing, and supporting OT or SCADA systems, ideally within utilities or critical infrastructure.

• 1+ year of hands-on IT security experience, with a strong learning mindset.

• Solid understanding of Zero Trust security principles and network, OS, and identity services including IAM and PAM.

• Experience with cloud infrastructure, monitoring tools, and network security technologies.

• Strong communication and collaboration skills, with the ability to advise both technical and non-technical stakeholders.
