WELCOME TO SITA
At SITA, we keep airports moving, airlines flying smoothly, and borders open. Our technology and communication innovations power the success of the global air travel industry. You'll find us in 95% of international airports, working closely with over 2,500 transportation and government clients.

We don't just move the world forward-we're proud to be recognized as a
Great Place to Work
® by 79% of our employees and certified in most of our growing locations. Here, we feel empowered, supported, and inspired to grow. Are you ready to love your job? The adventure begins right here, with you, at SITA. PURPOSE
As a Lead Penetration Tester in the Security Assurance & Testing team of the SITA Enterprise Information Security Office, you will find and verify security weaknesses in SITA products and infrastructure before attackers or customers do. You will lead pentests from scoping to closure.
You will also direct the technical work of internal and contracted pentesters and make sure their reports meet SITA quality standards. You will help move SITA from manual, point-in-time pentesting to continuous, AI-assisted security testing. KEY RESPONSIBILITIES
Run authorized penetration tests on SITA applications, APIs, mobile apps, AI components, cloud environments and infrastructure. Use attacker techniques to confirm how exploitable each weakness is and what it would affect. Lead walkthrough and scoping sessions with product and technical teams.
Define the test scope and write the pentest plan. Collect and validate prerequisites such as environments, credentials, test data and DAST scan results. Give technical direction to internal and contracted pentesters during testing. Unblock testers when they hit technical problems and escalate issues that would put the test or its timeline at risk. Review reports for technical accuracy, CVSS scoring and remediation advice before publishing them on the pentest reporting platform. Raise alerts on critical findings as soon as they are confirmed.
Explain findings and their business impact to development teams, operations, product owners and management. Present results during triage calls. Perform or supervise retests. Confirm fixes and produce the summary reports and attestations that SITA shares with customers and regulators. Run root-cause analysis on critical and high findings. Feed the lessons learned back to product teams, future test plans and pentest suppliers. Evaluate and use AI-assisted pentesting tools. Decide which tasks the tools can run on their own and which need a human tester to check the results.
Research and develop testing tools, techniques and methodology. Contribute to automating security testing in CI/CD pipelines. Advise on secure design through threat modelling and architecture reviews. Share current attacker techniques with the incident response and threat monitoring teams.
