About the Team

You will join a fast-growing technology team dedicated to realizing the IATA MAR vision. The team builds solutions based on the OOSD (Offer, Order, Settle, Deliver) domain model using API-first, event-driven, and cloud-native technologies. By adopting domain-driven architecture, we enable agile product teams to deliver scalable, modular, and interoperable systems.

About the Job

As a Security Architect, you will design secure architectures, implement IAM, Zero Trust, and DevSecOps principles across systems, and lead security governance activities.

Responsibilities:

• Design end-to-end security architectures across application, network, data, and cloud layers
• Implement IAM solutions (e.g., Keycloak or equivalent) and access control mechanisms
• Apply Zero Trust principles, mTLS, WAF, Vault and encryption strategies
• Perform threat modeling using Threat Modeling Manifesto principles and apply models such as STRIDE, LINDDUN, CIA, DIE, and PLOT4ai
• Produce modeling diagrams (DFDs, Attack Trees, Sequence Diagrams, etc.)
• Integrate DevSecOps into CI/CD pipelines; automate security scans using tools like OWASP ZAP, Trivy, Snyk or equivalents
• Implement IaC security controls and policy enforcement (e.g., OPA Gatekeeper, Terraform scanning or equivalents)
• Ensure compliance with standards and regulations (ISO 27001, PCI-DSS, GDPR/KVKK)
• Lead penetration testing, risk assessments, and security audits
• Design and coordinate incident response processes and run tabletop/exercise scenarios
• Promote secure-by-design principles and mentor development teams on secure coding practices

Qualifications:

• Minimum 7 years of experience, preferably 10+ years in security architecture or cybersecurity
• Deep expertise in cloud security and IAM solutions across public cloud and on-prem/hybrid environments
• Proficiency in threat modeling and producing modeling diagrams (STRIDE, LINDDUN, CIA, DIE, PLOT4ai)
• Practical experience with DevSecOps tooling and automation in CI/CD pipelines
• Hands-on knowledge of IaC security checks, policy-as-code, and automated scanning workflows
• Strong understanding of security and compliance standards (ISO 27001, PCI-DSS, GDPR/KVKK)
• Experience in penetration testing coordination, risk management, and incident response orchestration
• Strong leadership, stakeholder communication, and governance capabilities
• Security certifications are a plus (e.g., CISSP, CISM, OSCP, CEH)

Example project experience (optional, preferred): Experience designing security architecture for large-scale, multi-domain systems (e.g., major financial platforms, telecom infrastructures, or airline ecosystems) is preferred.

Note: Experience in large-scale, multi-domain transformation projects is considered an asset.
