Integrate hardware interfaces such as SPI, I2C, GPIO, and related components. Support integration of USB Power Delivery, PMIC, and battery thermal protection. Debug issues at Linux kernel level using logs, registers, and low-level diagnostics. Work closely with hardware engineers, reading schematics and datasheets. Support Android AOSP / HAL or graphics framework integration. Create or support hardware testing tools, with Python as a plus. Investigate complex technical issues independently and propose practical solutions. Key competences Strong C programming skills, including pointers, bit masks, memory-level work, and development without relying on standard libraries. Hands-on experience with Linux Kernel development and hardware drivers. Practical knowledge of embedded hardware interfaces such as I2C, SPI, GPIO, UART or similar. Experience with Device Tree configuration and modification. Ability to read hardware schematics and datasheets. Experience debugging kernel-level issues using tools such as adb, dmesg, kdbg, kernel logs or similar. Strong problem-solving mindset and ability to work independently. Good communication skills and readiness to collaborate closely with hardware and software teams. Nice to have Experience with MediaTek platforms. Experience with Android AOSP, system builds, or HAL modifications. Knowledge of USB Power Delivery. Experience with EPD / E-Ink displays. Knowledge of Li-Ion battery charging standards, including JEITA. Python, Java or other scripting/programming experience. Experience in consumer electronics, mobile devices, wearables, IoT or embedded hardware products. Salary and Conditions Full-time position. Employment contract or B2B contract. Hybrid work model: 4 days per week from the office in Warsaw, near Racławicka metro station. Flexible working hours. Salary: to be discussed, depending on experience. Benefits Opportunity to work on real consumer electronics products, not only software abstraction layers. Direct impact on hardware-software integration and product performance. Work with Linux Kernel, embedded systems, E-Ink technology, and power management. Private medical care, Multisport funding, and English language lessons. Additional days off under B2B cooperation. 2 paid volunteering days. A product-driven environment focused on quality, simplicity, and meaningful technology.
