Mobile Systems Engineer

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 behavior.

If you enjoy diagnosing low-level performance bottlenecks and building high-quality mobile systems that feel smooth across diverse devices, this role is for you

• Build and optimize high-performance mobile applications across Android and iOS platforms.
  
• 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 Android and/or iOS native development.
  
• Strong understanding of mobile performance optimization principles.
  
• Experience with native bridge integrations using Java/Kotlin/Swift/Objective-C.
  
• 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.
