Full Job Description

Are you looking for an opportunity with plenty of growth potential? Do you enjoy working in an exciting, fast-paced, collaborative environment? Are you interested in working with the world’s most innovative companies to create a more connected world?

Connecting Continents. Impacting Communities.

The backbone of the Internet is a series of high-tech subsea fiber optic cables deployed throughout the globe - SubCom has deployed over 50% of them. Our employees ensure data communications networks are engineered, manufactured, deployed to the highest standards, enabling faster and more reliable connectivity to communities worldwide. Every member of the SubCom team plays a role in an end-to-end process that is critical to enterprises, governments, big cities, and rural towns.

We encourage, expect, and value creativity, thoughtful risk taking, openness to change, and diverse perspectives. Whether you’re a seasoned applicant seeking a new and exciting challenge, or you’re new to the workforce and looking for a flexible, rewarding, and fast-paced position with an innovative and stable organization (since 1953), SubCom has opportunities to advance your career.

Responsibilities

Monitor and analyze security events across corporate IT, remote sites, vessel networks, cloud platforms, and customer-connected environments to identify and respond to threats in real time.
Lead initial cybersecurity incident triage and response activities, including containment, escalation, root cause analysis, recovery coordination, and post-incident documentation.
Conduct proactive threat hunting and security analysis using SIEM, endpoint, network, and cloud telemetry to identify emerging threats and anomalous activity.
Administer, maintain, and optimize cybersecurity technologies including SIEM, endpoint protection, firewalls, VPNs, MFA, and intrusion detection/prevention systems.
Oversee vulnerability management activities including scanning, risk prioritization, remediation coordination, and validation with NOC IT Engineers and infrastructure teams.
Manage identity and access security controls including VPN certificate lifecycle management, privileged access reviews, MFA enforcement, and least-privilege administration.
Coordinate penetration testing, security assessments, and remediation activities for internal, external, and customer-facing systems and services.
Maintain and strengthen the overall cybersecurity posture of the NOC and supporting infrastructure through continuous monitoring, hardening, and security best practices.
Support cloud and infrastructure security initiatives across Azure, AWS, GCP, servers, endpoints, and network environments, ensuring secure configuration baselines and asset visibility.
Ensure compliance with ISO 27001, customer security requirements, and internal cybersecurity policies through documentation, control validation, and continuous improvement activities.
Support internal and external audits, regulatory reviews, and customer security assessments by maintaining audit-ready evidence, procedures, and training records.
Develop and maintain cybersecurity dashboards, metrics, reports, policies, procedures, and security awareness training to improve operational readiness and visibility.
Coordinate with NOC personnel, IT teams, vendors, MSPs, and customer stakeholders to support cybersecurity operations, remediation efforts, disaster recovery preparedness, and secure change management activities.

Qualifications

Bachelor’s degree in Cybersecurity, Information Technology, or related field (or equivalent experience)
Ability to monitor and analyze security events in a NOC/SOC environment
Strong troubleshooting and incident triage skills
Experience with scanning tools and remediation tracking
Understanding of TCP/IP, VPNs, firewalls, and distributed networks
Familiarity with endpoint protection, IDS/IPS, and security platforms
Knowledge of ISO 27001, NIST, or similar frameworks
Ability to collaborate across IT, NOC, and customer teams
Excellent written and verbal communication skills

Our selection procedure is based on local, state and federal law.
