Core Responsibilities

Primary Functions

Develop, articulate, and execute a multi-year enterprise information security strategy that aligns with company objectives, reduces risk exposure, and supports secure growth and digital transformation initiatives.
Lead the design and implementation of a layered security architecture (network, cloud, application, data, endpoint, identity) that supports business agility while enforcing security controls and Zero Trust principles.
Own enterprise risk management for cyber and information risks: identify, assess, prioritize, and mitigate risk across business units and technology domains, and maintain an up-to-date risk register and remediation roadmap.
Create and maintain an incident response program, lead major incident response efforts, coordinate cross-functional response teams, conduct post-incident root cause analysis, and implement continuous improvement based on lessons learned.
Build, manage, and mentor a global security organization including SOC, threat intelligence, vulnerability management, identity and access management (IAM), security engineering, and security governance teams; recruit and retain top security talent.
Establish and operate security monitoring and detection capabilities (SIEM, XDR, logging, threat hunting) to ensure rapid detection, investigation, and containment of security events and orchestration of automated playbooks where appropriate.
Define and maintain security policies, standards, and procedures; ensure consistent enforcement across the technology stack and business processes to reduce risk and support auditability.
Lead secure software development initiatives and DevSecOps practices by integrating security into the SDLC, threat modeling, code review, SCA, and CI/CD pipelines to reduce application and supply-chain risk.
Own identity and access control strategy: design centralized IAM, SSO, privileged access management (PAM), least-privilege models, role-based access control, and lifecycle processes for provisioning and deprovisioning.
Oversee vulnerability management program, including vulnerability scanning, prioritized remediation, patch management, and coordination with engineering and operations teams to close critical exposures promptly.
Direct cloud security strategy and controls across multi-cloud environments (IaaS, PaaS, SaaS): cloud security posture management, secure configuration baselines, network segmentation, encryption, key management, and cloud-native monitoring.
Manage third-party and vendor risk by establishing security requirements for vendor selection, conducting security assessments and audits, driving contractual security obligations, and monitoring third-party compliance.
Ensure regulatory, contractual, and industry compliance (e.g., SOC 2, ISO 27001, PCI DSS, HIPAA, GDPR) by developing and executing compliance programs, supporting internal and external audits, and maintaining certification readiness.
Partner with legal, privacy, finance, HR, and business leaders to align security with business needs, support incident communications, regulatory reporting, and contract negotiations that include security clauses.
Develop and manage the security budget, capital and operating expenditures, and business cases for security investments; measure ROI and present risk-based spending recommendations to the executive team and board.
Architect and drive business continuity, disaster recovery, and cyber resilience planning to ensure rapid recovery of critical services and minimize operational and reputational impact after incidents.
Lead threat intelligence and strategic threat hunting initiatives to proactively identify emerging adversary techniques, adapt defenses, and inform leadership of evolving threats and their business impact.
Provide regular, concise, and quantifiable reporting to the executive team and board on risk posture, major incidents, program maturity, KPIs, and the effectiveness of security investments.
Drive security awareness and culture across the organization through training programs, phishing simulations, executive briefings, and embedding security accountability into product and operational teams.
Oversee digital forensics and investigative efforts when breaches or suspicious activity occur, coordinating evidence collection, legal preservation needs, and support for law enforcement if required.
Create and maintain metrics and KPIs to measure program effectiveness (MTTR, detection rate, number of critical vulnerabilities, patch cycle time, compliance status) and use them to drive continuous improvement.

Secondary Functions

Support business development and customer-facing security reviews, including responding to RFP security questionnaires, preparing security attestations and whitepapers, and presenting security posture to customers and partners.
Collaborate with product management and engineering to define secure-by-design requirements for new products and features, ensuring security is integrated early and cost-effectively.
Maintain and update runbooks, playbooks, and tabletop exercises to test readiness for ransomware, data exfiltration, insider threat, and supply chain compromise scenarios.
Participate in industry information sharing (ISACs, forums) and external security communities to benchmark practices, share threat intel, and represent the organization in security initiatives.
Coordinate cross-functional projects such as secure migrations, M&A security due diligence and integration, and major platform upgrades with security controls baked into project plans.
