Selected by the India AI Mission, MeitY to build India’s Scientific Foundation Model (SFM), we are advancing the nation’s sovereign AI capabilities while creating adaptive, intelligent systems that empower research, industry, and society. Job Description Mobile Systems Engineer Bengaluru ZenteiQ Full Time Experience - 3 to 6 years ZenteiQ is building a next-generation mobile application focused on delivering exceptionally fast, responsive, and reliable user experiences across Android and iOS platforms. We are looking for engineers who are deeply passionate about mobile performance engineering and scalable mobile systems. This role goes beyond standard application development — it involves solving hard engineering problems related to startup time, UI responsiveness, memory optimization, battery efficiency, and offline-first application behaviour you enjoy diagnosing low-level performance bottlenecks and building high-quality mobile systems that feel smooth across diverse devices, this role is for you. Key Responsibilities: ● Build and optimize high-performance mobile applications across Android and iOS platforms. ● Collaborate closely with UI/UX designers to translate design specs into fluid, pixel-perfect interfaces while maintaining design system integrity. ● Improve application startup time, rendering performance, and responsiveness across core user journeys. ● Diagnose and eliminate memory leaks, UI lag/jank, and battery drain issues. ● Develop reliable offline-first application workflows with efficient local data handling. ● Write and maintain performant native integrations and mobile system bridges where required. ● Participate in device-level testing, profiling, and performance benchmarking. ● Collaborate with engineering teams on scalable architecture and production delivery quality. ● Drive engineering best practices around performance optimization and application reliability. Requirements Required Skills ● Strong React Native experience with production-grade mobile applications. ● Experience with Cross platform application development like Flutter is mandatory. ● Experience with other cross platform or native environments is strongly sought after like Kotlin Multiplatform with Compose UI frameworks, Kotlin for Android and/or Swift for iOS native development. ● Strong understanding of mobile performance optimization principles. ● Experience with native bridge integrations using Flutter is mandatory and integration experience with Kotlin/Swift/Objective-C is preferred. ● Strong debugging and troubleshooting mindset. ● Experience building offline-capable mobile applications. ● Familiarity with memory profiling, render optimization, and battery efficiency concepts. ● Strong testing discipline and production-quality engineering practices.
