About Us

KAT Enterprise LLC is a fast-growing digital health and AI innovation company revolutionizing how people access and interact with health and wellness solutions. We are seeking a highly skilled Senior Mobile App Developer with deep expertise in native mobile development and a passion for building intelligent, user-centered mobile experiences using cutting-edge technologies.

Position Summary

We are looking for an experienced Mobile App Developer who can design, build, and maintain advanced applications for both Android and iOS platforms using native programming languages (Kotlin/Java for Android and Swift/Objective-C for iOS). The ideal candidate is up to date with the latest development frameworks, mobile UX trends, and has real-world experience integrating AI-powered features (e.g., machine learning, natural language processing, computer vision, voice recognition).

This is a high-impact role that involves close collaboration with our design, backend, AI, and product teams.

Key Responsibilities

• Design, develop, and maintain native Android and iOS applications from concept to deployment.
• Collaborate with product managers, designers, and backend developers to create seamless user experiences.
• Integrate AI-driven features using APIs or on-device models (e.g., TensorFlow Lite, CoreML, OpenAI APIs).
• Optimize applications for performance, quality, security, and responsiveness across devices.
• Build reusable components and scalable architecture for future use.
• Conduct code reviews, troubleshoot, debug, and resolve app issues promptly.
• Stay updated with latest trends, tools, SDKs, and development best practices in both Android and iOS ecosystems.
• Ensure compliance with platform-specific design guidelines (Material Design, Human Interface Guidelines).
• Work with DevOps teams to support CI/CD pipelines and manage mobile app releases.

Required Qualifications

• 5+ years of native mobile app development experience on both Android (Kotlin/Java) and iOS (Swift/Objective-C).
• Demonstrated experience with modern mobile architectures such as MVVM, VIPER, or Clean Architecture.
• Experience building and releasing apps on the App Store and Google Play.
• Solid understanding of RESTful APIs, GraphQL, and mobile data storage (SQLite, Room, Core Data).
• Proven experience integrating AI and ML libraries/APIs, such as:
• TensorFlow Lite
• CoreML
• OpenAI APIs
• Google ML Kit
• Voice and image recognition frameworks
• Familiarity with cloud-based services (e.g., Firebase, AWS Mobile Hub, Azure App Center).
• Knowledge of mobile security practices, including encryption, secure storage, and data protection.
• Strong problem-solving skills, analytical thinking, and attention to detail.
• Experience with automated testing frameworks (e.g., XCTest, Espresso, Detox).



Preferred Qualifications

• Experience with WearOS, watchOS, or IoT integrations.
• Familiarity with ARKit/ARCore for immersive features.
• Exposure to cross-platform tools (e.g., Flutter, React Native) is a plus but not a substitute for native experience.
• Past work in health tech, mental health, or wellness domains is a strong advantage.
• Published portfolio of apps demonstrating advanced features and AI integration.
