OT Cybersecurity - Network Security Professional

OT Cybersecurity Professional

Contract: 6 Months

Juno Beach, FL (Local Candidates Required)

We are seeking an OT-focused cybersecurity professional to strengthen our nuclear plant’s cyber governance, architecture, and compliance posture. This role emphasizes design oversight, documentation, compliance, and coordination across Operations, Engineering, Maintenance, and IT. You will not be expected to perform routine hands-on work on plant control systems; instead, you will develop and maintain the documentation, requirements, and oversight needed to ensure digital systems meet regulatory, safety, and security objectives.

Minimum Qualifications

·       Bachelor’s degree in Cybersecurity, Computer Science, Electrical/Computer Engineering, or related field; or equivalent relevant experience.

·       5+ years of experience in OT/ICS cybersecurity, network engineering, or related roles within critical infrastructure (power, oil/gas, manufacturing, or similar). Nuclear experience preferred but not required.

·       Strong understanding of OT/ICS environments and constraints (DCS, PLCs, safety systems, HMIs, historians), and common industrial protocols (e.g., Modbus, DNP3, OPC).

·       Proven experience with network security architecture and controls: segmentation/zoning, firewalls/ACLs, VPN, IDS/IPS, jump servers, and unidirectional gateways/data diodes.

·       Familiarity with cybersecurity frameworks and guidance relevant to OT, such as NIST SP 800-82 and ISA/IEC 62443, and the nuclear regulatory context (10 CFR 73.54, NRC RG 5.71, site CSP).

·       Demonstrated excellence in technical writing and documentation: procedures, configuration baselines, risk assessments, test plans, and audit evidence under formal document control.

·       Experience supporting audits/inspections and managing corrective actions through a CAP.

·       Understanding of change/configuration management within a quality assurance program (10 CFR 50 Appendix B or similar).

·       Strong communication and stakeholder management skills; ability to influence without authority in a highly regulated environment.

·       Ability to obtain and maintain unescorted access authorization (UAA) and meet fitness-for-duty requirements. On-call and off-hours support as needed.
