Senior Specialist Cyber Security

You will be the backbone of Infineon’s Cyber Security Incident Response Team (CSIRT).

Job Description

In your new role you will:

• Lead and support the triage, containment, eradication, and recovery of security incidents that affect Infineon’s global information systems, products, and services.
• Operate and refine the CSIRT’s playbooks, runbooks, and escalation matrix for all cybersecurity domains (network, endpoint, cloud, embedded, and supply chain).
• Coordinate with the Joint Operations Centre (JOC), Threat-Intelligence, Vulnerability Team, and external partners to ensure a unified, rapid response.
• Maintain a detailed incident documentation, conduct root‑cause analyses, and produce concise after‑action reports that drive continuous improvement.
• Participate in tabletop exercises, red‑team/blue‑team drills, and periodic reviews of the CSIRT program to keep it aligned with industry best‑practice frameworks.
• Use the CSIRT triage matrix to assess severity, scope, and potential impact of alerts from SIEM, EDR, network monitoring, and external threat‑intel sources.
• Deploy containment strategies (e.g., network segmentation, quarantine of infected endpoints, and malicious file removal) and work with system owners to eradicate threats.
• Plan and execute safe restoration of services, validate system integrity, and coordinate with the IT Service Desk to minimize downtime.
• Perform analysis of computers /servers activity, memory dumps, disk images, network packet captures, and log correlation to identify attacker techniques, persistence mechanisms, and data exfiltration paths.
• Maintain a secure, audit‑ready incident log; produce post‑mortem reports with timelines, findings, mitigations, and lessons learned.
• Evaluate new CSIRT tools (SOAR, threat‑intel platforms), recommend upgrades, and integrate them into existing workflows.
• Deliver incident updates to executive management, product teams, and external regulators; coordinate legal and PR responses when required.
• Conduct security incident drills for cross‑functional teams and mentor junior CSIRT analysts.
• Ensure incident handling meets GDPR, NIST, and relevant internal compliance requirements.
