How you'll help us Keep Climbing (overview & key responsibilities)

Here, you’ll work on complex challenges ona global scale, using augmented intelligence to build emergingtechnologies, amplify human potential and continuously grow the skills thatkeep you at the forefront of what’s next.

Technology drives the innovation that enriches our customers' experience, and the FlyDelta mobile app is where millions of travelers meet that experience every day. We’re looking for an App Developer who builds for that scale and wants to shape how our team works, not just what we ship.

This role sits at the front of how we’re modernizing development: using AI to drive spec-driven design, turning clear requirements into well-architected, production-ready code. If you’re energized by pairing strong mobile engineering fundamentals with emerging AI-assisted workflows, and you want your work in the hands of customers on every Delta journey, the stage is ripe for disruption. We’re calling on thought-leaders ready to create meaningful, innovative solutions that help us realize our vision.

Responsibilities

• Drive spec-driven, AI-accelerated development. Turn clear, well-formed requirements into production-ready code, using AI to accelerate design, generation, and review while staying fully accountable for the architecture and the outcome. Treat specs as living contracts, keeping requirements, design, and implementation in sync so the team moves fast without losing sight of why a feature exists.
• Write resilient, secure, quality-first code. Deliver code that degrades gracefully and recovers cleanly, anticipating failure modes so a single dependency never grounds the experience. Put automation at the forefront for continuous quality with Test-Driven Development as a central practice, and adhere to information security best practices at every layer.
• Build a flexible, event-driven, server-driven app. Architect the FlyDelta mobile app so new features and journeys ship without a full release cycle and adapt to customers in real time.

Apply expert skill in mobile technologies (Android, Kotlin, Java, Node.js) and cloud-native technologies (AWS) with a strong command of design patterns, continually growing your expertise and staying current on industry practices. Familiarity with iOS, Swift, XCUI, SwiftUI, and AI prompting is a strong plus.

• Ability to build secure apps that adhere to best practices for information security.
• Ability to build high-performing apps focused on a balance of data stored in app vs. servers to interact for end consumers, and continuous focus on improvement of performance.
• Hands-on experience with AWS cloud-native technologies, including designing or consuming APIs to deliver flexible, dynamic app features.
• Technical Expertise - Involves demonstrating a commitment to increasing knowledge and skills in current technical/functional area, keeping up to date on technical developments, staying informed as to industry practices, and knowing how to apply relevant technical processes to appropriate business needs.
