  • Implement and enforce Data Loss Prevention (DLP) policies, tools, and controls to prevent unauthorized data transfers, including hands-on work with data classification and monitoring systems.
  • Perform detailed data flow mapping to understand how customer data moves across internal systems, SaaS apps, APIs, and third-party integrations.
  • Secure cloud environments (AWS preferred) including data at rest and in transit using encryption and cloud-native security tools.
  • Manage cloud access policies, network segmentation, secrets management, and continuous monitoring.
  • Support compliance frameworks including GDPR, SOC 2, ISO 27001, and crypto-specific security standards as required.
  • Develop and maintain internal security policies, procedures, and security controls.
  • Partner with the Data Protection & Information Security Officer to ensure alignment across security, privacy, and data governance.
  • Serve as the Access & Control Monitoring expert, managing IAM, RBAC policies, least-privilege access, MFA, and anomaly detection systems.
  • Perform regular access reviews, privilege audits, and segregation-of-duty checks.
  • Maintain strong audit logging practices and monitoring of access behavior.
  • Deliver training, simulations, and internal education to strengthen internal security awareness.
  • Lead phishing simulation programs and social engineering prevention initiatives.
  • Lead the incident response process: detection, escalation, containment, investigation, and post-incident review.
  • Maintain and improve the incident response playbook; run annual and quarterly tabletop exercises.
  • Collaborate with engineering teams to embed secure-by-design practices into our SaaS products.
  • Conduct application security reviews, threat modeling, and code analysis (bonus).
  • Contribute to architecture decisions for new features and infrastructure.
  • 3+ years of experience in cybersecurity, information security, or security operations.
  • Hands-on experience with Data Loss Prevention (DLP) tools and data classification frameworks.
  • Strong data flow mapping expertise with the ability to trace data across systems, integrations, and APIs.
  • Solid understanding of cloud security concepts, encryption, and cloud-native security tools (AWS preferred).
  • Expertise in IAM and Access Control Monitoring, including least-privilege models, RBAC, MFA, and anomaly detection.
  • Familiarity with audit logging, SIEM tools, vulnerability management, and endpoint security.

  • Strong understanding of MITRE ATT&CK, threat actors, and common attack vectors.
  • Working knowledge of compliance standards such as GDPR, SOC 2, and data protection regulations.
  • Excellent communication skills and the ability to collaborate with technical and non-technical teams.
