• Contribute to OT/ICS cybersecurity guardrails to ensure OT architectures, solutions, and technologies are designed and implemented using secure-by-design methodology.

• Utilize industry standards and frameworks such as NIST SP 800-53, NIST SP 800-82, and ISA/IEC 62443 to identify security capabilities and technologies that strengthen OT defenses.

• Support cybersecurity risk assessments to determine system criticality, exposure, and risk gaps.

• Provide recommendations and mitigation plans for issues identified through OT/ICS cybersecurity reviews, risk assessments, and vulnerability assessments.

• Provide subject matter leadership during cyber incidents, including response, containment, and remediation.

• Some travel, up to 20%, may be required.
