We are looking for a Senior Embedded C Developer with strong experience in Zephyr RTOS to join our engineering team. You will be responsible for developing, optimizing, and maintaining firmware for embedded devices that power our next-generation products. This role requires deep technical expertise in low-level programming, real-time operating systems, and hardware-software integration.

Primary Duties:

• Design, implement, and maintain embedded software using C/C++ on Zephyr RTOS.
• Develop and integrate device drivers, communication protocols, and hardware abstraction layers.
• Collaborate closely with hardware and systems engineers to ensure reliable operation across various platforms.
• Optimize performance, memory usage, and power efficiency of embedded systems.
• Implement and maintain build systems, continuous integration, and testing pipelines for firmware projects.
• Debug and troubleshoot hardware/software issues using oscilloscopes, logic analyzers, and JTAG tools.
• Ensure code quality through code reviews, unit testing, and adherence to best practices.
• Contribute to system architecture design and documentation.

Required Skills:

• 5+ years of experience in embedded software development (C/C++).
• Proven experience with Zephyr RTOS (or similar RTOS such as FreeRTOS, ThreadX, or NuttX).
• Strong understanding of ARM Cortex-M microcontrollers and peripheral interfaces (SPI, I2C, UART, GPIO, etc.).
• Experience with hardware bring-up, debugging, and performance optimization.
• Proficiency in version control systems (Git) and build systems (CMake, West, or similar).
• Understanding of real-time constraints, interrupt handling, and memory management.
• Familiarity with CI/CD workflows and embedded test automation.
• Intermediate or higher level of English for technical documentation and communication.

Nice-to-Have Skills:

• Experience with Bluetooth Low Energy (BLE), Thread, CAN, or other communication stacks.
• Knowledge of secure boot, OTA updates, and device provisioning.
• Familiarity with embedded Linux or hybrid systems combining RTOS and Linux.
• Experience with hardware design tools (schematics review, PCB layout understanding).
• Contributions to open-source Zephyr projects or similar communities.

We Offer:

• Employment in a stable, well-recognized international company.
• Competitive salary and benefits package.
• A supportive and professional team environment with strong engineering culture.
• Flexible working hours and the option for hybrid work.
• Comprehensive medical insurance and wellness support.
• Opportunities for professional development, conferences, and internal training.
• A culture that encourages innovation, technical ownership, and continuous improvement.
