Responsibilities
Build and optimize core connectivity features
Design and implement robust Bluetooth Low Energy (BLE) solutions in C++/C/Kotlin for iOS and Android platforms. You'll handle complex connection states, manage central and peripheral roles, and ensure our Bluetooth stack delivers the low-latency, high-throughput performance our distributed database requires
Extend our protocol capabilities
Implement new Bluetooth profiles and features that expand Ditto's connectivity options. You'll work on advertising strategies, scanning optimization, and connection management to maximize device discovery and pairing success across diverse environments
Ensure reliability at scale
Build sophisticated error handling and recovery mechanisms that gracefully manage Bluetooth's inherent unreliability. Your code will need to handle edge cases, interference patterns, and the quirks of thousands of different device models in production
Optimize for the real world
Tune performance across multiple dimensions—latency, throughput, connection stability, and power efficiency. You'll profile code, identify bottlenecks, and make architectural decisions that balance competing constraints
Create robust testing infrastructure
Develop automated testing frameworks (primarily Python-based) that validate Bluetooth performance across diverse device types, OS versions, and real-world scenarios. You'll build the tools that give us confidence in every release
Collaborate across the stack
Work closely with mobile app developers, platform engineers, and product teams to integrate Bluetooth seamlessly with other transport layers (Wi-Fi Direct, LAN) and ensure a unified sync experience
Qualification
Required
7+ years of software engineering experience with at least 3-4 years focused on Bluetooth development
Deep expertise in Bluetooth Low Energy (BLE) protocols, profiles, and the Bluetooth Core Specification
Strong proficiency in C++/C and experience with mobile development in Kotlin (Android) and/or Swift/Objective-C (iOS)
Experience with Rust or strong willingness to learn and work in a Rust environment
Proven track record of shipping production Bluetooth features in mobile applications
Experience debugging complex connectivity issues across diverse device ecosystems
Strong understanding of networking fundamentals, state machines, and asynchronous programming
Ability to write clean, maintainable code with comprehensive test coverage
Preferred
Production experience with Rust in systems programming or networking contexts
Experience with Bluetooth Mesh or other mesh networking protocols
Background in distributed systems or peer-to-peer networking
Familiarity with other local transport protocols (Wi-Fi Direct, NFC, etc.)
Python scripting for test automation and tooling
Experience with performance profiling and optimization on mobile platforms
Open source contributions to Bluetooth-related projects
Knowledge of embedded systems or IoT device development
