• Handle race conditions and real-world concurrency scenarios between multiple apps, users, and physical access methods
• Collaborate closely with firmware engineers to implement and validate communication protocols and authentication sequences

• Ensure SDK reliability, maintainability, performance, and developer-friendly API design

   

Requirements:
 

• 5+ years of commercial Flutter/Dart development experience
• Strong experience building and shipping production mobile applications
• Proven hands-on experience working with Bluetooth Low Energy (BLE) in real-world environments

• Experience supporting BLE functionality across both iOS and Android
• Solid understanding of REST API integration and asynchronous application architecture
• Experience working with secure storage, authentication flows, and token-based systems

• Strong debugging and problem-solving skills, particularly around connectivity issues and device-level edge cases

   

Nice to Have:
 

• Experience building and maintaining Flutter packages or SDKs
• Background in IoT, smart devices, access control, or hardware-integrated applications
• Familiarity with cryptography, encryption protocols, and secure communication patterns
• Experience collaborating with embedded or firmware engineering teams
• Knowledge of mobile platform internals related to Bluetooth and background processing
• Experience designing public-facing APIs for external developers
   

What We Offer:
 

• Fully remote engagement with flexible working arrangements
• Opportunity to build a core product used by enterprise and public sector customers
• Challenging technical work involving mobile, cloud, BLE, security, and hardware integration
