Sr. Cybersecurity Engineer

Sr. Cybersecurity Engineer

The WBD Security Engineering team empowers the WBD Global Information and Content Security (GICS) organization by supporting Security Engineering, Security Architecture, Threat Detection & Response, and other security functions through the deployment, management, and evolution of scalable, resilient, and intelligent security platforms.

The Sr. Cybersecurity Engineer plays a key role in advancing WBD's security capabilities by ensuring modern security tools, processes, and automation frameworks are effectively designed, implemented, and maintained. This role will focus on Endpoint Detection & Response (EDR), SIEM, and emerging AI-driven security capabilities, with an emphasis on building a more intelligent and automated security ecosystem.

The ideal candidate will have strong experience with SentinelOne (or comparable EDR platforms), Splunk (or similar SIEM tools), and hands-on exposure to AI/ML and generative AI technologies, including the ability to leverage vendor-native AI features and build custom automation or AI-driven solutions to enhance threat detection, investigation, and response.

Key Responsibilities

• Plan, design, engineer, and implement enterprise security technologies with a focus on EDR, SIEM, and AI-driven security capabilities
• Build, manage, and optimize enterprise security platforms, including SentinelOne and Splunk (or equivalent tools)
• Integrate AI and automation into security operations to improve detection, response, and remediation workflows
• Identify opportunities to enhance the organization's overall security posture through modern tooling and intelligent automation

Core Focus Areas

EDR & Endpoint Security

• Lead the design, deployment, and optimization of SentinelOne (or similar EDR platforms)
• Develop and tune detection rules, behavioral analytics, and response mechanisms
• Investigate endpoint threats and improve response playbooks and automation
• Ensure endpoint visibility, coverage, and resilience across environments

SIEM & Data Analytics (Splunk or Equivalent)

• Design and maintain SIEM solutions to support centralized logging, monitoring, and alerting
• Ingest and normalize data from diverse sources (endpoints, network, cloud, applications)
• Develop dashboards, alerts, and detection use cases to support SOC operations
• Optimize performance, scalability, and cost-efficiency of SIEM platforms

(Note: Splunk experience remains important, but flexibility with other SIEM platforms is acceptable.)

AI, Automation & Innovation

• Leverage built-in AI capabilities within security tools (EDR, SIEM, SOAR, etc.)
• Design and implement AI-driven workflows, including the use of generative AI and AI agents for threat analysis, triage, and response
• Build or integrate automation using scripting (Python, APIs) and orchestration tools
• Evaluate and pilot emerging AI/ML security technologies to enhance detection and response

Additional Responsibilities

• Collaborate with SOC, engineering, and infrastructure teams to integrate security tools across the enterprise
• Conduct security assessments and continuously improve detection and response capabilities
• Troubleshoot and resolve complex platform and integration issues
• Develop documentation, standards, and operational procedures
• Mentor junior engineers and promote knowledge sharing across teams

Qualifications & Experiences :

• 5+ years of hands-on experience with enterprise security platforms (EDR, SIEM, SOAR)
• Strong experience with SentinelOne (or similar EDR solutions)
• Experience with Splunk or other SIEM platforms in large-scale environments
• Hands-on experience with AI/ML, generative AI, or security automation use cases
• Experience building or integrating AI-driven workflows, scripts, or agents is highly desirable
• Proficiency in scripting (Python or similar) for automation and integrations
• Experience with cloud environments (AWS, Azure, GCP) and security integrations
• Strong understanding of security architecture, threat detection, and incident response
• Familiarity with compliance and regulatory frameworks

Not required but preferred experience :

• Security certifications (e.g., CISSP)
• Splunk certifications or equivalent SIEM expertise
• Experience with SOAR platforms and automation frameworks
• Exposure to AI/ML frameworks, LLMs, or security-focused AI tooling
