Role Overview:

We are seeking a Cybersecurity Engineer to help secure our organization’s systems and data through a combination of hands-on engineering and governance, risk, and compliance (GRC) practices. In this role, you will apply cybersecurity best practices, risk management, and vulnerability management to protect the organization’s confidentiality, integrity, and availability. You will identify threats and risks, implement effective security controls, and support monitoring and incident response activities.

You will operate with a high degree of independence, designing and executing enterprise-grade security solutions aligned with regulatory requirements and industry frameworks. The ideal candidate is both technical and analytical, capable of translating compliance requirements into practical solutions while driving continuous improvement across security operations. This role reports to the Sr. Cybersecurity Manager and follows a hybrid work model.

Key Responsibilities:

• Design, implement, and maintain enterprise-grade security solutions aligned with regulatory requirements and frameworks (e.g., NIST, NERC CIP)
• Operate with a high degree of independence, driving security initiatives end-to-end from design through implementation
• Monitor, detect, and respond to cyber threats and vulnerabilities across IT and OT environments
• Lead or support incident response activities, ensuring timely containment, remediation, and documentation
• Maintain and improve incident response playbooks, runbooks, and tabletop exercises
• Conduct risk assessments, vulnerability scans, and remediation tracking, focusing on measurable risk reduction
• Track emerging threats and translate threat intelligence into improved detections and controls
• Perform and support security validation activities, including penetration testing and control testing
• Translate GRC requirements into practical technical controls and sustainable processes
• Support and enforce security policies, standards, and procedures, ensuring audit readiness
• Contribute to and evolve security architecture across identity, network, cloud, and OT environments
• Collaborate with IT and business teams to embed security into systems and operations
• Implement, tune, and optimize security technologies (SIEM, EDR, IDS/IPS, etc.)
• Analyze logs and alerts to identify and investigate suspicious activity
• Support implementation of data protection and encryption controls
• Prepare and maintain security documentation and audit artifacts
• Support third-party risk management and vendor security reviews
• Provide technical guidance and mentor team members, acting as a deputy when needed
• Promote a culture of security awareness and continuous improvement
• Support security of OT/ICS environments, including SCADA systems and NERC CIP-aligned controls

Preferred Qualifications:

• Bring a strong GRC foundation but can translate governance requirements into real technical controls
• Have hands-on experience with NERC CIP or regulated environments
• Can independently drive risk, compliance, and security improvement initiatives end-to-end
