Summary

The role works closely with development and QA teams to embed security into the full software lifecycle, covering threat modelling, secure coding, vulnerability management and PCI compliance.

• Review code and binary scan results, working with developers to fix vulnerabilities during development
• Assess and manage existing vulnerabilities using CVSS, define remediation actions and track progress
• Support PCI-DSS compliance by collecting audit evidence with dev, QA and platform teams
• Work with QA to ensure adequate security test coverage across functional and non-functional testing

About the Ideal Candidate:

• Relevant experience in software development (.NET), application security, or infrastructure security (AWS/Azure);
• Strong knowledge of secure development practices, threat modeling, and vulnerability management;
• Excellent communication, collaboration, and problem-solving skills;
• Experience with Amadeus LSS and Amadeus Robotics is a plus.
