- Manage and optimize enterprise security tools (EDR, SIEM, vulnerability scanners, identity management, firewalls).
- Conduct threat hunting and forensic analysis to identify suspicious activity across endpoints, networks, and cloud environments.
- Oversee vulnerability management lifecycle from scanning and prioritization to remediation and reporting.
- Maintain and enhance incident response playbooks; lead tabletop exercises and post-incident reviews.
- Collaborate with IT, engineering, and compliance teams to ensure controls are implemented and effective.
- Provide operational guidance on compliance frameworks (e.g., NIST SP 800-171, CMMC Level 2).
- Build and maintain dashboards, metrics, and executive-level reports on overall security posture.
- Interface with MSSPs, investigate escalations, and coordinate control improvements.
Satellite Penetration Testing
- Plan, scope, and execute authorized penetration tests for York's satellites and supporting ground infrastructure in controlled, non-flight environments.
- Conduct reconnaissance, vulnerability scanning, and exploit validation for spacecraft subsystems, payload interfaces, command and telemetry links, and ground-station software, as authorized.
- Work with mission operations, systems engineering, and legal/safety teams to ensure testing aligns with operational and export-control requirements.
- Analyze penetration test findings, document exploitable paths, and produce risk-ranked reports with technical and executive summaries.
- Communicate vulnerabilities, mission impacts, and remediation priorities to engineering and management teams.
- Validate remediation effectiveness through follow-up testing and control verification.
REQUIRED QUALIFICATIONS:- Bachelor's Degree in Cybersecurity, Computer Science, Information Systems, or related field AND 6 years of directly related experience in IT, networking, or security, OR an equivalent combination of education and experience.

- Scripting/programming skills (e.g., Python, PowerShell, Bash) for automation and exploit validation in controlled test environments.
- Knowledge of threat intelligence platforms and adversary tactics (MITRE ATT&CK).
- Experience in security awareness training and phishing simulations.
- Experience conducting authorized penetration testing or red/purple team operations on mission-critical systems, preferably in aerospace, satellite, or other embedded/industrial environments.
- Understanding of satellite and ground-segment architectures (telemetry, command links, payload interfaces, bus subsystems, and mission operations networks) or willingness to learn domain-specific systems.
- Working knowledge of secure coding, embedded security, or firmware testing concepts is a plus.
- Experience mentoring junior analysts or leading small project teams.
- Strong communication skills with both technical and non-technical stakeholders.
