Core Responsibilities

Primary Functions

Develop and own a multi-year enterprise information security and privacy strategy that aligns with business objectives, regulatory requirements (e.g., GDPR, HIPAA, PCI-DSS), and emerging threat landscapes; present strategy, roadmap and risk posture to the Board and executive leadership on a regular cadence.
Lead the security organization — hiring, mentoring and scaling teams across security operations (SOC), incident response, identity and access management (IAM), application security, cloud security, threat intelligence, vulnerability management, and security engineering — setting OKRs and ensuring high-performance delivery.
Design, implement and continuously improve an enterprise risk management program that identifies, quantifies and mitigates cyber, third‑party, and operational risks, and embeds security risk appetite into business decision-making and investment prioritization.
Build, operate and mature 24x7 security operations including SIEM, EDR, threat hunting, log management, incident detection and response, and playbooks to reduce mean time to detect (MTTD) and mean time to remediate (MTTR).
Own incident response and crisis management: lead response to major security incidents, coordinate cross-functional teams, manage external communications, engage legal and PR, and run post-incident root cause analyses and remediation tracking.
Establish and run a robust vulnerability management and penetration testing program — prioritize and track remediation of critical vulnerabilities, manage third-party red/blue team engagements, and integrate findings into secure development lifecycle (SDLC).
Architect and enforce identity and access management strategy including least privilege, role-based access control, privileged access management (PAM), multi-factor authentication (MFA), and lifecycle processes for onboarding/offboarding.
Define and enforce secure architecture and engineering principles across on-premises, hybrid and cloud environments (AWS, Azure, GCP), including container, serverless and microservices security, infrastructure-as-code (IaC) scanning, and DevSecOps pipelines.
Lead privacy and data protection initiatives in partnership with legal and product teams: data classification, data loss prevention (DLP), data subject rights processes, privacy impact assessments, and secure data handling practices.
Maintain compliance and audit readiness for regulatory and industry frameworks (SOC 2, ISO 27001, NIST CSF, PCI-DSS), coordinate external audits, remediate findings, and produce evidence and reports for auditors and regulators.
Establish and monitor KPIs, metrics and dashboards (e.g., risk heat maps, compliance posture, vulnerability trends) to measure program effectiveness and communicate security health to technical and non-technical stakeholders.
Manage security budget and vendor portfolio: evaluate, select and negotiate contracts for security tools and MSSPs, measure vendor SLAs, and ensure third-party risk assessments and remediation obligations are enforced.
Drive security awareness and behavior change across the organization: design role-based training, simulated phishing programs, executive briefings, and security champions networks to reduce human risk and improve compliance.
Integrate security into product and engineering lifecycles through secure coding standards, threat modeling, code review requirements, SAST/DAST/IAST tooling, and pre-release security gates to reduce vulnerabilities in production.
Lead enterprise-wide business continuity, disaster recovery and resilience planning for cyber incidents: define RTO/RPO objectives, run tabletop exercises, and ensure critical systems recovery and continuity of operations.
Own cloud-native security strategy including cloud access security brokers (CASB), cloud workload protection platforms (CWPP), cloud security posture management (CSPM), and secure networking architecture (VPCs, subnets, service meshes).
Oversee third-party and supply chain risk management: vendor security assessments, contract security clauses, continuous monitoring, and remediation plans for critical suppliers and SaaS providers.
Drive adoption of Zero Trust principles across identity, device posture, network segmentation and application-level controls, including technology selection and phased rollout planning.
Provide strategic security guidance and technical due diligence for M&A activity: evaluate target security posture, define integration remediation plans, and ensure secure onboarding of acquired assets.
Maintain and evolve security governance, policies and standards; chair or participate in security steering committees and ensure policies are practical, enforceable and aligned with business needs.
Collaborate with engineering, product, legal, HR and finance to advise on new product launches, platform changes, or major projects to ensure security and compliance are incorporated from design through production.
Lead threat intelligence and risk-informed defense: consume and operationalize external threat feeds, industry-specific indicators of compromise (IOCs), and competitor/sector threat actor assessments to proactively defend the enterprise.
Serve as the public-facing security executive for customers, partners and regulators: respond to security questionnaires, lead executive briefings, participate in customer audits, and provide security attestations and incident reports.
Continuously benchmark and improve the security program against industry best practices (e.g., NIST, ISO 27001, CIS Controls), emerging technologies and peer organizations to drive maturity and competitive advantage.

Secondary Functions

Support ad-hoc executive inquiries and board-level reporting requests with clear, data-driven security status updates, risk treatment plans and investment justification materials.
Contribute to the organization’s overall risk and resilience strategy by collaborating with business continuity, legal, privacy and compliance teams to align plans and response playbooks.
Participate in cross-functional product and engineering planning sessions to translate security requirements into actionable engineering tasks and acceptance criteria.
Provide mentorship and career development for security leaders and key individual contributors, establishing succession plans and technical competency frameworks.
Partner with procurement and legal to define contractual security requirements for vendors, SLAs and data processing agreements to reduce supply chain and third-party risk.
Drive continuous improvement processes for security incident closure, remediation verification, and lessons-learned integration into policies and controls.
