Security Engineer

ECS is seeking a Security Engineer to work in their Portland, OR office or remotely. The Security Engineer will support the design, implementation, configuration, and maintenance of cybersecurity technologies and controls to ensure the protection and monitoring of systems and networks.

Responsibilities:

• Implement, configure, maintain, and support cybersecurity technologies, tools, platforms, and technical security controls
• Assist with engineering secure solutions for enterprise systems, networks, endpoints, cloud environments, applications, and operational support platforms
• Support security architecture decisions by providing implementation input, technical feasibility analysis, and operational considerations
• Apply security engineering practices across the system lifecycle, including planning, deployment, configuration, testing, operations, and sustainment
• Apply secure configuration baselines, hardening standards, and technical control requirements to servers, endpoints, network devices, applications, and cloud services
• Review system configurations, permissions, authentication settings, logging settings, encryption settings, and access controls for alignment with security requirements
• Support implementation of vulnerability remediation, configuration changes, patching activities, and risk reduction measures in coordination with system owners
• Validate that security controls are operating as intended and support remediation when control gaps or technical weaknesses are identified
• Support deployment, tuning, and sustainment of tools such as SIEM, EDR, vulnerability scanners, firewalls, IDS/IPS, email security, identity security, logging, and monitoring platforms
• Integrate security tools with enterprise systems, data sources, ticketing systems, dashboards, identity platforms, and incident response workflows
• Troubleshoot tool performance, connectivity, data collection, alerting, agent health, policy enforcement, and integration issues
• Coordinate with SOC analysts, Splunk engineers, threat hunters, and system administrators to ensure security tooling supports monitoring, investigation, and response requirements
• Analyze vulnerability scan results, configuration findings, security alerts, and control weaknesses to support prioritization and remediation planning
• Work with technical teams to identify root causes, validate remediation options, and confirm closure of vulnerabilities or security findings
• Support risk treatment activities by documenting technical constraints, compensating controls, residual risk, and remediation status
• Assist control assessors and assessment leads by providing technical evidence, configuration details, screenshots, logs, and implementation explanations
• Provide technical engineering support during security incidents, investigations, containment activities, eradication efforts, and recovery actions
• Assist with log collection, tool validation, endpoint or network containment actions, access changes, system isolation, and forensic preservation activities as directed
• Develop and maintain scripts, queries, automation, and repeatable procedures to improve security operations and engineering response efficiency
• Participate in after-action reviews and support implementation of technical improvements based on incident lessons learned
• Develop and maintain technical documentation, configuration standards, diagrams, implementation guides, runbooks, and operational procedures
• Support change management, configuration management, asset documentation, and security engineering governance processes
• Recommend improvements to security tools, engineering processes, baselines, automation, monitoring coverage, and technical control implementation
• Stay current with emerging threats, security technologies, hardening guidance, and engineering best practices relevant to enterprise security environments

Requirements:

• Hands-on experience implementing and supporting security tools
• Troubleshooting technical security issues
• Applying secure configuration standards
• Collaborating with SOC analysts, system administrators, network engineers, control assessors, and program stakeholders to improve the organization's security posture
• Implement, configure, maintain, and support cybersecurity technologies, tools, platforms, and technical security controls
