Firmware Application Developer

Neybo is an AI companion device for kids. Unimatch Lab is an AI-agent-run venture builder with seven products across Future of Work, Longevity, Kids Universe, and Education.

• Design and implement the device state machine, including operating modes, transitions, and timeout handling
• Build the C++ UI and rendering layer, separating product logic from platform-specific code
• Run the application end to end on a Linux laptop or tablet before target hardware is available
• Implement Wi-Fi onboarding and pairing as part of the state machine, integrated with the device network stack
• Implement the OTA and factory reset mechanisms
• Integrate third-party components, such as wake-word recognition and voice quality enhancement
• Implement telemetry and crash reporting to the backend
• Support the device security audit
• Support QA regression testing and system benchmarking procedures, including display performance indicators
• Design for the final embedded target’s memory and performance constraints from the start
• Prototype early application versions on a Linux computer
• Coordinate interfaces with the Firmware Lead Engineer so the application and system layers combine into a single firmware image

• 4+ Years of commercial C++ development
• Production experience with modern C++, including object lifetime, RAII, STL, threading and concurrency, and error handling
• User-space application development experience on Linux or POSIX
• Experience with event-driven or state machine design, including explicit states and transitions, event loops, timeouts, and recovery handling
• Experience building a GUI or application-layer UI; Qt/QML is the clearest signal, but other C++ UI stacks count
• Experience writing platform-independent code by separating product logic from platform adapters, including running part of a product on desktop or x86 before target hardware is available
• Practical TCP/IP and Wi-Fi onboarding or provisioning experience, such as NetworkManager/D-Bus, wpa_supplicant, or a SoftAP/captive portal flow
• English B2+, written and spoken
• Будет плюсом: Qt 5/6, QML/Qt Quick, Qt State Machine or SCXML, ARM cross-compilation, Yocto or Buildroot integration, D-Bus, systemd, hostapd, mDNS/DNS/DHCP beyond basic Wi-Fi pairing, AOSP/Android TV or JNI/NDK, device OTA, rollback, crash dumps or remote diagnostics, experience shipping a consumer device into production

• Paid in USDT
• B2B contract
