Job Description

IT Security Manager – Global Enterprise

We are seeking a detailed and results-oriented leader to join our global Information Technology team as an IT Security Manager . This role is critical to the success of our cybersecurity program, with responsibility for leadership, strategy, and execution of security engineering services and our cybersecurity tool stack.

Key Responsibilities

  • Define and execute the vision, strategy, and roadmap for security architecture and engineering across the enterprise, leveraging leading frameworks such as NIST and implementing Zero Trust principles for robust perimeter-less security.
  • Partner with cross-functional and platform teams to embed security-by-design, least privilege, and defense-in-depth principles into solutions and the development lifecycle, ensuring integration of SAST and DAST tools for continuous secure code reviews and vulnerability detection.
  • Oversee the delivery, integration, and optimization of the enterprise security architecture and tool stack, including next-generation SIEM platforms and technologies such as Splunk for real-time threat monitoring and advanced analytics.
  • Champion and automate incident response and security operations using SOAR solutions to streamline threat detection, remediation workflows, and playbook execution.
  • Drive continuous improvement of security processes, governance, methodologies, and tools, emphasizing cloud-native protections and best practices for AWS environments.
  • Translate business risks into scalable, practical security solutions that exceed policy mandates and regulatory requirements, leveraging insights from SIEM and SOAR data.
  • Recruit, coach, and scale a high-performing team of security engineers, providing both strategic and tactical oversight in modern enterprise environments.
  • Leverage data-driven approaches and security KPIs—sourced from SIEM/Splunk, code analysis reports, automated SOAR outputs, and AWS metrics—to monitor and strengthen organizational security posture.

What Will Set You Apart

  • Passion for cybersecurity and solving complex problems using innovative techniques and modern automation (SOAR, Zero Trust, cloud security).
  • Proven track record in designing and implementing secure architectures for enterprise applications, networks, security platforms, and AWS cloud deployments.
  • Expertise in integrating and managing SIEM technologies, specifically Splunk , for monitoring, dashboarding, and advanced threat analytics.
  • Advanced knowledge of NIST Cybersecurity Framework (CSF), securing cloud environments (AWS), and experience implementing Zero Trust architectures.
  • Hands-on experience with secure code analysis tools and methodologies, including SAST and DAST , and integrating these into CI/CD pipelines.
  • Advanced experience with DevSecOps practices, automating security workflows using SOAR platforms, and embedding security in agile development lifecycles.
  • Strong communication skills for breaking down complex technical concepts, threat intelligence, and incident reports for technical and non-technical stakeholders.
  • Deep understanding of regulatory and compliance requirements (PCI DSS, GDPR, SOX), threat modeling, and defending against advanced persistent threat groups.

Requirements

  • Bachelor’s degree in Computer Science, Cybersecurity, or a related technical field.
  • 5+ years of hands-on experience designing and delivering innovative security solutions, including SIEM (e.g., Splunk), AWS cloud, and security automation (SOAR).
  • 3+ years leading security engineering/operational teams with demonstrated success integrating security tooling such as SAST, DAST, and SIEM.
  • Experience collaborating cross-functionally, communicating risks, supporting a Zero Trust approach, and setting security priorities informed by frameworks like NIST.
  • Demonstrated commitment to high ethical standards, regulatory compliance, and business integrity across hybrid/multicloud environments.
