• Perform basic forensics on endpoints and servers (disk, memory, network artifacts).
• Build, maintain, and test IR playbooks and tabletop exercises.

Vulnerability & Patch Management

• Run and interpret vulnerability scans for IT and OT assets; track remediation with IT/OT stakeholders.
• Support risk-based patching strategy, considering production windows and system criticality.

OT/ICS Security (Manufacturing)

• Support customer/vendor assessments, third-party risk reviews, and audit evidence collection.

Awareness & Continuous Improvement

• Create concise guidance for employees and engineers; run phishing simulations & training.
• Tune detections, enhance automated response (SOAR), and measure control effectiveness with KPIs/KRIs.

Qualifications

• 3-5+ years in cyber security (SOC, incident response, threat analysis, or blue team).
• Experience with SIEM (e.g., Splunk, Securonix, Microsoft Sentinel), EDR/XDR (e.g., Microsoft Defender, CrowdStrike, Trend Vision One), and email security.
• Solid understanding of network security (Fortigate, Palo firewalls, IDS/IPS, NAC), Windows/Linux internals, and identity security (CyberArk, Azure AD/AD, MFA, conditional access).
• Hands-on experience with incident response and vulnerability management (Tenable, Qualys).
• Ability to work with manufacturing/OT stakeholders and communicate risks in business terms.
• Bachelor's in Cyber Security, Information Systems, Computer Science, Engineering, or related field; or equivalent practical experience.
