The posting
Summary of Position:
Responsible for planning, managing, and implementing cybersecurity and IT compliance to ensure effective enterprise protection and innovation in the organization.
We are looking for an intermediate-level Security Engineer who can support Alcon’s Cyber Incident Response and Threat Management function across AWS cloud security, SIEM monitoring, EDR/XDR operations, cloud incident response, and emerging AI security risks. This person should be hands-on, practical, and comfortable working with SOC, Cloud, Infrastructure, Identity, and application teams to improve threat detection, response, and security posture.
Role Expectations:
- Monitor, investigate, and respond to security alerts across cloud, endpoint, identity, email, SaaS, and enterprise environments.
- Take ownership of assigned incidents from triage through containment, remediation support, documentation, and lessons learned.
- Work with internal teams and external SOC partners to ensure incidents are handled consistently and within defined operational expectations.
- Contribute to detection improvements, playbook maturity, operational documentation, and knowledge sharing across the SOC team.
Key Responsibilities:
1. AWS Security Incident Response & Cloud Security
- Investigate AWS security alerts, suspicious activity, misconfigurations, and potential compromise scenarios using available cloud logs and security tooling.
- Review AWS security findings from services such as GuardDuty, Security Hub, CloudTrail, Config, IAM, CloudWatch, Inspector, and related monitoring sources.
- Support containment and remediation activities for cloud security incidents in coordination with Cloud Engineering and application owners.
- Identify gaps in cloud logging, monitoring, alerting, access control, and security posture, and recommend practical improvements.
- Assist in building and maintaining cloud incident response runbooks, investigation steps, and escalation procedures.
- Enhance incident detection and response capabilities for Cloud platforms.
2. SIEM Monitoring & Detection Engineering
- Work on Microsoft Sentinel and other SIEM-related monitoring activities to detect, investigate, and correlate threats across multiple data sources.
- Create, review, and tune SIEM use cases to improve alert quality and reduce false positives.
- Support onboarding and validation of important log sources including cloud, identity, endpoint, email, firewall, SaaS, and application logs.
- Develop dashboards, basic reporting, and operational metrics to improve visibility for SOC and leadership stakeholders.
- Map detections and investigation logic to common attacker behaviors using MITRE ATT&CK where applicable.
3. EDR / XDR Operations
- Investigate EDR/XDR alerts from platforms such as Microsoft Defender XDR and other endpoint security tools.
- Perform endpoint triage, device isolation support, IOC validation, malware investigation, and remediation coordination.
- Identify endpoints missing security coverage and work with responsible teams to support remediation and visibility improvement.
- Support policy tuning, alert validation, and operational improvements to strengthen endpoint detection and response.
- Coordinate with Infrastructure, Desktop Engineering, and Vulnerability Management teams where endpoint issues require ownership outside SOC.
4. AI Security & Secure AI Operations
- Support security monitoring and investigation of AI-related risks such as unauthorized AI usage, data leakage, prompt injection, model misuse, risky plugins/connectors, and AI-assisted phishing or social engineering.
- Assist in defining practical AI security guardrails for SOC usage, including access control, logging, acceptable use, data handling, and escalation criteria.
- Contribute to AI security incident response workflows and help document how AI-related security events should be triaged and escalated.
- Support secure use of Microsoft Security Copilot and other AI-enabled security tools by helping validate use cases, risks, controls, and operational logging needs.
- Stay current on AI threat trends and translate them into practical SOC monitoring and response actions.
5. Incident Response, Threat Hunting & Continuous Improvement
- Perform structured incident analysis including scope identification, timeline review, evidence collection, containment recommendations, and post-incident documentation.
- Participate in threat hunting and proactive detection improvement activities across cloud, endpoint, identity, and SIEM data.
- Create and maintain SOC knowledge articles, incident handling guides, detection notes, and runbooks.
- Support internal and external audit requests by providing clear operational evidence where applicable.
- Identify automation opportunities using SOAR, scripting, KQL, PowerShell, Python, or cloud-native capabilities to reduce repetitive manual effort.
Key Requirements/Minimum Qualifications:
- 5–7 years of experience in SOC operations, incident response, cloud security, SIEM engineering, EDR/XDR operations, or a related cybersecurity role.
- Hands-on experience with AWS security concepts including IAM, logging, monitoring, network security, encryption, and incident investigation.
- Working knowledge of AWS security services such as GuardDuty, Security Hub, CloudTrail, Config, Inspector, IAM, and CloudWatch.
- Experience with SIEM tools, preferably Microsoft Sentinel, including alert investigation, KQL/log analysis, rule tuning, and dashboard/reporting support.
- Experience with EDR/XDR platforms, preferably Microsoft Defender XDR, including endpoint investigation, containment, and remediation coordination.
- Support secure adoption of AI capabilities by identifying security risks, monitoring misuse scenarios, and helping define security guardrails.
- Good understanding of incident response lifecycle, threat hunting, common attack techniques, and MITRE ATT&CK.
- Basic scripting or query skills using KQL, PowerShell, Python, or similar technologies.
- Good written communication skills with the ability to document incidents, actions taken, findings, and recommendations clearly.
Preferred Qualifications
- AWS Certified Security – Specialty, AWS Solutions Architect Associate, or equivalent cloud security certification.
- Microsoft SC-200, SC-100, AZ-500, GCIH, GCIA, or similar security certifications.
- Experience working in a global SOC or managed security operations model.
- Exposure to Microsoft Security Copilot, SOAR platforms, threat intelligence platforms, or automation workflows.
- Experience in regulated environments such as healthcare, life sciences, or global enterprise operations.
