What You Will Do

The Cybersecurity Engineer at EXOS owns the security stack that powers our SOC. You keep our detection and prevention tools healthy, current, and tuned across every client environment, and you find coverage gaps early. You report to the Security Operations Manager and serve as the engineering escalation point for Cybersecurity Analysts I, II, and III.

This is a hands-on builder role. You will deploy, upgrade, and integrate tools, measure how well they protect each client, and bring clear recommendations on what to improve next. The role is built for an engineer with 5+ years in security or infrastructure engineering who enjoys making a multi-tenant stack run cleanly at scale.

• Own administration and health of the SOC security stack, including security tools like SentinelOne, CrowdStrike, Splunk, Cisco Firepower, Cisco ASA, Cisco Umbrella, DNSFilter, Avanan, and our security awareness training platform.
• Plan and deliver platform updates, agent upgrades, policy changes, and version lifecycles across client tenants. Every change goes through change control with testing, a maintenance window, and a rollback plan.
• Deploy and onboard security tooling for new clients, including agent rollout, log source integration, policy baselines, and handoff documentation for the SOC.
• Onboard log sources, maintain parsing and field extractions, monitor for stalled or missing sources, and keep license and storage use on target.
• Build, tune, and maintain detections and correlation searches with the SOC analysts. Reduce false positive load and close coverage gaps mapped to MITRE ATT&CK.
• Maintain perimeter and DNS security posture. Review Cisco Firepower and ASA rule sets, IPS policies, and VPN configurations, and manage Cisco Umbrella and DNSFilter policies across tenants.
• Support phishing simulations and training campaigns in the security awareness platform.
• Identify gaps across people, process, and technology. Run regular coverage reviews for agent deployment, log sources, and policy drift, benchmark against CIS Controls and NIST CSF, and present prioritized recommendations to the Security Operations Manager.
• Evaluate new tools and features. Run proofs of concept, compare vendors, manage vendor support cases, and build business cases that weigh risk reduction, operational effort, and cost.
• Automate repetitive work with PowerShell, Python, and platform APIs, and partner with the AI Automation Engineer on SOAR playbooks and integrations.
• Support analysts during incidents with containment actions, emergency blocks, and tooling troubleshooting, and take part in the after-hours escalation rotation.
• Keep engineering documentation current, including architecture diagrams, configuration standards, tool runbooks, and client-specific deployment notes.
