Project Description

Development of a portable, high-fidelity audio device integrated with AI assistant capabilities. The project focuses on creating a high-performance consumer electronics product with a focus on quality sound and battery efficiency.

Scope of Work

You will be responsible for the “brain” of the device, from low-level drivers to high-level application logic.

Firmware Development: Design and build applications, system features, and peripheral drivers from scratch.
Full-Cycle Engineering: Handle coding, debugging, and systematic troubleshooting throughout the entire development process.
System Validation: Perform rigorous testing to ensure hardware-software stability and feature performance.

We Expect You Are

Self-Driven & Autonomous: A proactive problem-solver who can navigate hardware documentation and drive tasks to completion independently.
Result-Oriented: Focused on delivering high-quality end products that align with business goals and reach the “Done” state.
A Strong Communicator: Able to articulate complex technical concepts clearly to both technical and non-technical stakeholders.
Flexible: Ready to quickly adjust to changing requirements, new technology stacks, or shifting project priorities.
Value-Driven: A contributor who looks beyond “just coding” to propose architectural improvements and process optimizations.
A Collaborative Team Player: Committed to knowledge sharing, active participation in code reviews, and supporting colleagues.

Deep proficiency in C/C++, including memory management, interrupts, and real-time constraints.
In-depth knowledge of Linux (Yocto/Buildroot, kernel-level debugging, device trees) and RTOS (FreeRTOS or similar) internals.
Proven track record in debugging, bug fixing, and system performance optimizations.
Ability to read datasheets/schematics and hands-on experience with oscilloscopes and logic analyzers.
Strong experience with peripheral (UART, SPI, I2C).
Proficiency in CMake, Bash, and Python scripting for automation and build systems.
Solid experience with Git, GitHub, and Jira.
Ability to create clear, maintainable technical specifications and code documentation (Doxygen, Wiki, Markdown).
English Proficiency: Upper-Intermediate (B2). Ability to conduct technical discussions, participate in meetings, and write professional documentation/emails for international clients.
