• Hands-on experience using Security Information and Event Management (SIEM) and Endpoint Detection and Response (EDR) technologies.
• Working knowledge of the MITRE ATT&CK framework and the NIST incident-response lifecycle.
• One or more relevant cybersecurity certifications, such as SANS GCIH, GCIA, CompTIA CySA+, or an equivalent credential.

• Strong analytical, problem-solving, documentation, and prioritization skills.
• Ability to communicate security findings, risks, and recommended actions to technical and non-technical stakeholders.

Preferred Skills/Experience

• Experience with digital forensics, threat hunting, malware analysis, or security automation and orchestration.
• Familiarity with cloud security, cloud-native security monitoring, and identity and access security.
• Experience developing or tuning SIEM correlation rules, EDR detections, alerts, dashboards, or response playbooks.
• Knowledge of cyber threat intelligence and common attacker tools, tactics, techniques, and procedures.
• Experience working in healthcare, pharmaceutical distribution, supply chain, or software environments.
• Familiarity with scripting or automation using Python, PowerShell, APIs, or SOAR technologies.
• Ability to rapidly learn, assess, and recommend new cybersecurity tools and technologies.
• Experience mentoring analysts or sharing technical knowledge across a security operations team.
