About the Role

We are seeking an experienced and self-driven Senior Mobile App and Console Developer to lead the architecture, design, and deployment of native and cross-platform mobile applications for both iOS and Android. In this role, you will own the end-to-end mobile development lifecycle, ensuring high-performance hardware/software integration and seamless user experiences. While your core expertise is mobile, a solid foundation in backend web development is essential to design efficient APIs, manage database architectures, and integrate mobile applications with scalable cloud infrastructure.

Responsibilities

• Architect, build, and maintain high-performance mobile applications for both iOS and Android platforms using native technologies (Swift/Kotlin) or cross-platform frameworks (React Native/Flutter).
• Design and implement robust backend services, RESTful APIs, and data models to support mobile features, prioritizing server-side security, business logic, and database management.
li>Collaborate directly with engineering leadership and cross-functional teams to translate complex hardware and client requirements into scalable technical solutions.
• Integrate mobile applications with embedded systems, Bluetooth/IoT devices, or third-party web services.
• Lead code reviews, enforce mobile/backend security best practices, and maintain automated CI/CD pipelines for App Store and Google Play deployments.
• Troubleshoot, debug, optimize, and maintain production backend infrastructure (e.g., Node.js, SQL/NoSQL databases, AWS) supporting mobile client ecosystems.

Qualifications

• 5+ years of professional experience building and deploying production-ready iOS and Android applications.
• Proven track record of published mobile applications on the Apple App Store and Google Play Store.
• Solid backend web development background, including experience designing RESTful/GraphQL APIs, managing databases (SQL/MongoDB), and server-side runtimes (e.g., Node.js, Python, or Go).
• Strong understanding of cloud services and deployment environments (AWS, Firebase, or GCP).
• Proficiency in mobile architecture patterns (MVVM, Clean Architecture), state management, and offline-first data synchronization.
• B.S. or M.S. in Computer Science, Computer Engineering, Software Engineering, or equivalent experience.

Preferred Qualifications

• Experience working in product development, IoT, hardware integration, or regulated manufacturing environments.
• Familiarity with web frontend frameworks (React, TypeScript) to support full-stack web needs when required.
• Knowledge of web security standards, OAuth, and encrypted data storage on mobile devices.

Skills

• Strong technical leadership with the ability to take full ownership of projects from concept through release.
• Exceptional analytical and troubleshooting skills to tackle complex system integrations.
• Strong communication, time management, and organizational skills.
