ICS/OT-Cybersecurity Engineer/Network Security Engineer - Memphis

ICS/OT Cybersecurity Engineers and ICS/OT Network Security Engineers support clients in assessing, improving, and maintaining the cybersecurity posture of their ICS/OT environments to mitigate security risks (e.g., insider and external threats, intentional and accidental).
This position's responsibilities include the audit of ICS/OT environments and performing risk/vulnerability assessments. This role also includes developing client specific cybersecurity roadmaps that prioritize the remediation of cyber threats, based on the likelihood of occurrence and magnitude of cost/consequence of a security incident. This position will create mitigation plans for clients to remediate vulnerabilities and will provide support during the remediation efforts. ICS/OT Cybersecurity Engineers and ICS/OT Network Security Engineers assist in reviewing and developing Industrial Cybersecurity programs, security policies, and plans, and provide guidance to help clients improve their existing OT security programs.
ICS/OT Cybersecurity Engineers and ICS/OT Network Security Engineers demonstrate:
• High integrity
• A willingness to go beyond the ordinary to meet and exceed client expectations
• A desire for continual challenge and development
• Excellent written and verbal communication skills
Reports to: Cybersecurity Lead
JOB QUALIFICATIONS
Responsibilities for this job include but are not limited to:

• Taking inventory of client's hardware & software assets and assessing those assets for security vulnerabilities, obsolescence, and other risks
• Reviewing network architectures and determining if good practices are being followed (e.g., the "zones & conduits" concept, proper network segmentation, use of Industrial DMZ, etc.); and providing recommendations to comply with applicable cybersecurity framework
• Reviewing security products utilized (e.g., firewalls, IDS, IPS) and determining if they are configured properly
• Deploying network infrastructure devices (e.g., switches, routers, etc.), security appliances (e.g., firewalls, IDS, etc.), and virtualization solutions
• Reviewing security policies, plans, and procedures; assessing network monitoring capabilities; analyzing system logs, security events, and packet captures to identify security threats; and providing recommendations to comply with applicable cybersecurity framework
• Reviewing administrative, technical, and physical security controls and providing recommendations to mitigate the identified security risks
• Performing vulnerability and risk assessments within manufacturing and critical infrastructure environments to identify security risks and threats (e.g., unsecure remote access points, suspicious remote connections, unauthorized devices on the network, etc.) and providing recommendation to remediate the identified issues
• Creating detailed diagrams (e.g., network, cabling, server, rack, logical architecture, etc.), procedures, and plans (e.g., implementation, SAT, mitigation, etc.) as needed to support projects
• Travel to the client's site as required

Required Experience

• Certified Information Systems Security Professional (CISSP)
• Degree in Engineering (Electrical, Mechanical, Chemical, or similar), Computer Science, or similar scientific / technical field
