Why This Role Matters The Senior Cybersecurity Engineer at Bluestaq owns the defensive posture of software systems that underpin national security decisions — space domain awareness, satellite command and control, and the infrastructure behind them. This is not a scan-and-report seat. You close vulnerabilities, build detection logic that catches real threats, and lead incident response when things get loud. No playbook required. If you need to be told what to look for, this isn't the right level. What You Own <ul> <li>Own the full vulnerability lifecycle — scanning with vulnerability management tools, triage by mission risk, remediation tracking, and verified closure across the fleet. </li> <li>Build and tune detection rules in SIEM tools (Splunk, Elastic, ArcSight, Sentinel, etc.) mapped to MITRE ATT&CK tactics relevant to Bluestaq's threat model. </li> <li>Serve as an incident responder for security events — contain, help scope, and provide clear status to the IR lead/leadership. </li> <li>Deliver written post-mortems with root cause, timeline, and tracked action items following incident closure. </li> <li>Maintain endpoint antivirus coverage across the fleet — configure policies, ensure definition currency, and coordinate remediation of flagged systems. </li> <li>Apply DISA STIGs to operating systems (Linux, Windows, etc.); document deviations and manage compliance artifacts (POA&Ms) in compliance management platforms (eMASS, Xacta, or equivalent RMF tools). </li> <li>Assist in CI/CD pipeline security — provide guidance as far left as possible in the development cycle to ensure developers are generating clean, secure code and catching vulnerabilities before they reach production.<span data-ccp-props="{"134233117":false,"1342331
