  • Manage vulnerability management as a unified process across all products.
  • Own ISO 27001, SOC 1, SOC 2, and PCI DSS compliance, including the audit calendar and auditor relationships.
  • Collaborate with legal and Data Protection Officer on data protection, residency, sub-processors, and customer contractual security commitments.
  • Own the business continuity and disaster recovery program, including testing and remediation.
  • Lead, develop, and retain a team of four security professionals.
  • Act as a sparring partner to leadership, challenging design decisions and advocating for appropriate risk trade-offs.
  • Contribute to technology strategy, ensuring security is integrated into customer migration plans.

Requirements

  • A career in security with hands-on technical experience prior to leadership.

  • Experience facing customers on security matters.
  • Working knowledge of ISO 27001 and SOC 2, with experience being accountable for audits and certifications.
  • Practical understanding of cloud security on AWS and Azure, Kubernetes-based platforms, infrastructure as code, and modern CI/CD.
