The Nuclear Company is the fastest growing startup in the nuclear and energy space creating a never‑before‑seen fleet‑scale approach to building nuclear reactors. Through its design‑once, build‑many approach and coalition building across communities, regulators, and financial stakeholders, The Nuclear Company is committed to delivering safe and reliable electricity at the lowest cost, while catalyzing the nuclear industry toward rapid development in America and globally.

We are seeking an exceptional and highly experienced Cybersecurity Engineer to join our growing team. This pivotal role will be responsible for designing, implementing, and maintaining advanced cybersecurity defenses across our IT and operational technology (OT) environments, ensuring the robust protection of our critical assets in a highly regulated industry.

The Cybersecurity Engineer will serve as a technical leader and subject matter expert in cybersecurity, focusing on securing both corporate IT systems and the specialized operational technology (OT) environments vital to nuclear energy operations. This role will involve strategic planning, hands‑on implementation, risk assessment, and ensuring compliance with stringent regulatory requirements. The successful candidate will drive the adoption of best practices, influence architectural decisions, and lead initiatives to strengthen our overall security posture against evolving threats.

This role reports into the VP, Software Engineering.

• Lead the design and implementation of secure architectures for both IT and OT systems, including network segmentation, access control, intrusion detection/prevention, and data protection.
• Develop and implement security standards, policies, and guidelines tailored to the unique demands of the nuclear energy industry.
• Evaluate and recommend new security technologies and solutions to enhance defense capabilities.

• Conduct comprehensive cybersecurity risk assessments for IT and OT systems, identifying vulnerabilities and potential threats.
• Develop and implement risk mitigation strategies and controls in accordance with industry best practices and regulatory requirements (e.g., NRC, NIST, IEC 62443).
• Lead vulnerability management programs, including penetration testing and security audits.
