Senior Software Development Engineer, Mobile

About the job

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

At Delta, we connect people and cultures, power extraordinary experiences, and shape the future of travel. Here, you'll work on complex challenges on a global scale, using augmented intelligence to build emerging technologies, amplify human potential and continuously grow the skills that keep 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. Leverage server-driven UI and API solutions to deliver dynamic features, balancing on-device and cloud data for high performance across millions of end customers.
• Bring deep mobile and cloud-native expertise. 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.
• Own outcomes and lift the team. Stay solution-oriented and forward-leaning, operate with integrity and trust, admit mistakes, and present the unvarnished truth helpfully. Work as a true team member who mentors, transfers knowledge, and defines success in terms of the whole squad.
