You will oversee the operation and upkeep of essential cybersecurity systems, including Security Information and Event Management (SIEM), Endpoint Detection and Response (EDR) systems, network access control (NAC), and Security Orchestration, Automation, and Response (SOAR) platforms.


Responsibilities :

  • Customize and optimize alert rules, correlation searches, and detection mechanisms within SIEM to align with security requirements and organizational objectives.
  • Deploy new SIEM instances including clustered deployments and apps.
  • Fine-tune EDR policies, rulesets, and scanning parameters to enhance endpoint visibility and threat detection capabilities.
  • Configure network access control policies within Forescout to enforce security posture and mitigate risks associated with unauthorized devices.
  • Support Linux environments, including editing and maintaining Splunk configuration files and apps.
  • Collaborate with other Cybersecurity Engineering team members and interact with end users to gather requirements, perform troubleshooting, and assist with the creation of Splunk search queries and dashboards.
  • Integrate cyber tools with a variety of legacy data sources.

Maintenance and Support :

  • Conduct routine maintenance tasks, such as software updates, patches, and performance tuning, to ensure the reliability and efficiency of cybersecurity systems.
  • Provide timely support and troubleshooting assistance to address issues and incidents related to SIEM, EDR, Forescout, and SOAR platforms, collaborating with vendors or higher-level support as necessary.
  • Perform regular system audits and health checks to identify vulnerabilities, misconfigurations, or performance issues, implementing corrective actions as needed.
  • Provide occasional presentations of tool capabilities to leadership.
  • Work with various procurement sections to evaluate, provision, and deploy cybersecurity products and services.

Policy Development and Compliance :

  • Develop and enforce configuration standards, security policies, and operational procedures for cybersecurity systems, ensuring compliance with regulatory requirements and industry best practices.
  • Monitor compliance with security policies and regulations through audits, assessments, and reporting activities, taking corrective actions to address any deviations or gaps.
  • Collaborate with compliance and audit teams to streamline regulatory compliance efforts and demonstrate adherence to security standards.

Integration and Automation :

  • Integrate cybersecurity systems with other security controls, data sources, and IT infrastructure components to create a cohesive security ecosystem.
  • Develop and maintain automation scripts, playbooks, and workflows within the SOAR platform (Swimlane) to automate routine tasks, orchestrate incident response processes, and enhance operational efficiency.
  • Explore opportunities for innovation and continuous improvement by leveraging automation, orchestration, and integration with emerging technologies and industry trends.

Training and Knowledge Sharing :

  • Provide training sessions and document processes to empower internal teams with the knowledge and skills required to effectively utilize cybersecurity systems.
  • Share expertise, best practices, and lessons learned with colleagues through formal and informal channels, fostering a culture of collaboration and knowledge sharing within the cybersecurity team.

Qualifications :

  • Bachelor's degree in Computer Science, Information Security, or a related field. Relevant certifications (e.g., Security+, CISSP, GIAC, Splunk Core Certified Power User) are advantageous.
  • 5+ years of experience in cybersecurity administration, with a focus on configuring and managing SIEM, EDR, network access control, and SOAR platforms.
  • Proficiency in Linux environments, including system administration tasks and shell scripting for automation and customization.
  • Solid understanding of cybersecurity principles, threat landscapes, and best practices for configuring and tuning security tools.
  • Strong analytical skills and attention to detail, with the ability to troubleshoot complex technical issues and optimize system performance.
  • Excellent communication and collaboration skills, with the ability to interact effectively with technical and non-technical stakeholders.
  • Demonstrated ability to work independently, prioritize tasks, and meet deadlines in a dynamic and fast-paced environment.
The likely salary range for this position is $85,000 - $115,000. This is not, however, a guarantee of compensation or salary.

Rather, salary will be set based on experience, geographic location and possibly contractual requirements and could fall outside of this range.
