Summary:

We are seeking an experienced Senior Security Specialist with a strong IT infrastructure background to help protect, secure, and continuously improve our organization's enterprise technology environment. This role combines hands‑on infrastructure knowledge with broad cybersecurity expertise across systems, networks, endpoints, identity and access management, cloud services, vulnerability management, security monitoring, and incident response. The Senior Security Specialist will work closely with IT infrastructure, networking, and business stakeholders to identify security risks, implement effective security controls, drive remediation efforts, and ensure security is integrated into technology operations and projects.

The ideal candidate understands how enterprise infrastructure is designed, deployed, maintained, and supported and can apply that knowledge to identify vulnerabilities, strengthen security configurations, and develop practical solutions that protect critical systems without unnecessarily disrupting business operations. This position requires a proactive, technically strong security professional who can work independently, lead security initiatives, influence technical decisions, and serve as a trusted resource for enterprise security matters.

Responsibilities:

• Enterprise Security and Infrastructure Protection
  • Develop, implement, and maintain security controls that protect enterprise infrastructure, systems, networks, endpoints, and cloud environments.
  • Assess infrastructure configurations and identify security weaknesses, misconfigurations, and opportunities to reduce the organization's attack surface.
  • Establish and promote secure configuration standards, system hardening practices, and infrastructure security baselines.
  • Evaluate technology designs and infrastructure changes to ensure appropriate security controls are implemented.
  • Provide technical guidance on security best practices, infrastructure protection, and risk mitigation.

Vulnerability and Risk Management

• Manage and coordinate vulnerability identification, assessment, prioritization, remediation, and validation across the enterprise.
• Analyze vulnerability scan results and prioritize findings based on severity, exploitability, asset criticality, exposure, and business impact.
• Work with system administrators, network engineers, and cloud teams to drive timely remediation.
• Track remediation activities, document exceptions, and communicate outstanding risks to appropriate stakeholders.
• Identify recurring security issues and recommend sustainable corrective actions.
• Provide reporting on vulnerability trends, remediation performance, and overall infrastructure risk.

Security Operations and Incident Response

• Investigate security alerts and suspicious activity involving enterprise systems, endpoints, identities, networks, and cloud resources.
• Collaborate with security operations teams to investigate, contain, remediate, and document security incidents.
• Support the use and continuous improvement of SIEM, EDR/XDR, logging, and threat detection capabilities.
• Analyze security events, authentication anomalies, malware detections, unauthorized changes, and indicators of compromise.
• Assist with incident response planning, root-cause analysis, recovery activities, and post-incident improvements.
• Identify opportunities to improve detection coverage, response procedures, and security monitoring across infrastructure environments.
• Coordinate technical remediation efforts with infrastructure and application support teams following security incidents.

Network, Endpoint, and Systems Security

• Support endpoint and server protection through EDR/XDR, antivirus, device compliance, and security configuration management.
• Identify unnecessary services, exposed ports, insecure protocols, and configuration issues that introduce risk.
• Promote secure administration practices and protection of critical infrastructure assets.
• Collaborate with technical teams to improve resilience, system integrity, and security visibility.
