- Strong understanding of advanced security concepts such as encryption, secure software design, identity management, and API security.

- Experience with cloud security (AWS, Azure, etc.) and securing microservices architectures.

- Proven leadership skills, with the ability to guide and mentor other engineers and influence security practices across teams.

- Excellent communication and collaboration skills, with a track record of working closely with cross-functional teams to improve security posture.

- 4+ years experience working as a Security Engineer / Application Security Analyst

### Preferred Qualifications:

### Our Cultural Pillars:

### Traveler first

We exist to create value for our customer, the traveler. We enable our suppliers and partners to unlock this value. Their collective behaviors and insights are what drives us.

### Execution is our edge

We act fast, experiment, learn from failure, iterate, and improve the solutions of tomorrow across every aspect of our business. Our execution is agile, data-driven, prioritised, and built to scale. We assume no problem is someone else’s problem and finish what can be done today, knowing tomorrow will bring fresh challenges.

### We succeed together

The best outcomes are driven by empathic, humble, and diverse subject matter experts working toward shared goals. We collaborate relentlessly, challenge assumptions, give actionable feedback, and set each other up for success through empowered teams with a clear charter. We transparently take ownership of our growth, individually and as a team. We celebrate the quality of our effort, our learnings, and our collective achievements.
