Qualifications

Bachelor’s degree in Computer Science or related field, or equivalent related professional experience.
8 years of relevant professional experience.
Professional experience building and shipping production mobile applications with Flutter and Dart, including ownership of features from design through release and support.
Experience delivering to both iOS and Android from a shared codebase, including API integration, data modeling, and network/offline data handling.
Demonstrated ability to design and maintain testable, maintainable, and performant mobile codebases using modern frameworks, tooling, and libraries.
Familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real‑world products, with a focus on safely integrating these capabilities into mobile features.

Responsibilities

Design, build, and maintain Layla’s cross-platform mobile experience in Flutter (Dart), delivering a single, high-quality codebase that performs reliably across iOS and Android.
Own end-to-end feature delivery for mobile — including low-level design, API integration, and data modeling — for conversational trip‑planning and booking features that connect to Layla and Expedia Group services.
Collaborate closely with Product, Design, and backend engineering to turn the conversational travel experience into intuitive, accessible, and performant mobile flows, iterating quickly based on experimentation and real traveler feedback.
Drive mobile quality and reliability through automated testing, continuous integration and delivery, performance monitoring, and observability across both platforms.
Safely integrate and operate AI/ML‑enabled capabilities within the app — such as assistant‑driven planning, personalization, and recommendations — applying AI/ML concepts to real‑world mobile features responsibly.
Contribute to native interoperability where platform‑specific capabilities are required, and help establish reusable patterns and engineering best practices for Flutter development at Layla.
