• Design and implement secure architectures for enterprise, operational, and control systems across Hadron’s network
• Develop and maintain cybersecurity frameworks aligned with NIST 800-53, NIST CSF, NRC, and DOE cybersecurity standards
• Configure, manage, and monitor security systems, including firewalls, SIEM, IDS/IPS, endpoint protection, and encryption protocols
• Conduct vulnerability assessments, penetration testing, and risk mitigation planning for both IT and OT assets
• Collaborate with engineering teams to secure instrumentation & controls (I&C), reactor monitoring systems, and industrial automation equipment
• Establish and enforce access controls, identity management, and network segmentation for sensitive environments
• Implement secure software development and deployment practices, supporting DevSecOps workflows
• Support incident response, forensic investigation, and recovery planning to ensure system resilience
• Document cybersecurity policies, network diagrams, and compliance reports for internal and regulatory review
• Stay current on emerging cyber threats, technologies, and regulations relevant to critical infrastructure and nuclear systems
• Partner with the Compliance and Regulatory teams to support audits and certification processes

• 5 years of experience in cybersecurity engineering or network/system security, preferably in energy, defense, or critical infrastructure sectors
• Strong understanding of industrial control systems (ICS), SCADA security, and operational technology (OT) network architecture
• Proficiency with security tools such as Splunk, Wireshark, Nessus, Metasploit, CrowdStrike, or equivalent platforms
• Deep knowledge of NIST, ISO 27001, and NRC cybersecurity requirements
• Hands-on experience with network design, firewall configuration, VPNs, and endpoint security
• Familiarity with cloud infrastructure security (AWS, Azure) and virtualization environments
• Relevant certifications such as CISSP, CEH, CISM, GICSP, or CompTIA Security are preferred
• Excellent analytical, troubleshooting, and documentation skills
• Ability to thrive in a collaborative, high-stakes environment with cross-disciplinary teams
• Passion for cybersecurity, advanced technology, and contributing to the protection of clean-energy innovation
