• Participate in code reviews, architectural discussions, and technical design sessions across a robust worldwide community of mobile and platform engineers to ensure best practices and maintainability.

• Contribute to CI/CD improvements, automated testing, and performance optimization for mobile applications.

• Identify and implement technical improvements that enhance reliability, accessibility, and customer satisfaction.

• Stay current with iOS development trends and help guide adoption of new technologies and frameworks.

Minimum qualifications:

• Bachelor’s degree in Computer Science or related technical field; or equivalent related professional experience.
• 2+ years of professional experience developing and shipping iOS applications using Swift.
• Experience with RESTful APIs, asynchronous programming, and mobile networking.

Preferred Qualifications:

• Experience developing and releasing apps at scale, including App Store submission and release processes.
• Experience with GraphQL APIs and server-driven UI frameworks.
• Experience working in AI-assisted development environments.
• Experience with backend technologies such as Java, Kotlin, or Node.js.
• Familiarity with continuous integration and delivery (CI/CD) systems and mobile testing frameworks.
• Strong understanding of performance tuning, accessibility, and analytics for mobile apps.
• Demonstrated ability to partner effectively across disciplines to deliver customer-focused features.
• Excellent problem-solving skills, attention to detail, and a passion for improving the traveler experience.
