Senior Embedded Platform Software Engineer (IoT)_Taipei

About the Team MediaTek’s IoT Business Unit is building the next-generation software foundation for Arm SoC platforms. The scope spans early chip bring-up, boot flow, secure firmware, and end-to-end Linux system integration, including boot firmware, kernel, Yocto, Ubuntu, and Debian solutions that are maintainable, scalable, and aligned with the standard Linux ecosystem. We are looking for a Senior Embedded Platform Software Engineer. In this role, you will work closely with hardware design, system architecture, validation, and operating system teams to bring Arm platforms from the bare-metal stage to a stable, production-ready system software environment. You will also help drive software standardization and participate in upstream activities, enabling long-term maintainability of system software in mainline projects and supporting the diverse product requirements and long lifecycle of IoT markets. If you are excited to work with a passionate and talented team to build world-class Arm-based Linux system software, this will be an excellent environment and challenge for you. ## What You'll Be Doing - Lead early bring-up for Arm SoC platforms, starting from bare-metal programs, memory initialization, UART, timer, interrupt, and other foundational peripherals to establish a debuggable environment. - Integrate and customize Arm Trusted Firmware-A (TF-A), including BL1 / BL2 / BL31 boot flow, secure monitor, exception level transitions, and platform-specific initialization. - Port, configure, and debug U-Boot to support storage devices, networking, Device Tree, boot parameters, and Linux kernel boot flow. - Integrate Linux kernel and platform support, including Device Tree, driver bring-up, SMP boot, power management, and system stability validation. - Implement and validate Arm PSCI interfaces to support CPU on/off, system reset, suspend/resume, and other power management and multi-core control features. - Analyze low-level boot issues using JTAG, trace, serial logs, logic analyzers, and other tools for debugging and root cause analysis. - Collaborate with hardware, firmware, OS, and validation teams to define platform boot flow, debugging strategy, and pre-production software quality standards. - Drive TF-A driver upstreaming so that platform support can stay aligned with the open-source community and mainline development over the long term. - Own the architecture design and development of built-in RISC-V firmware inside the SoC.

Main Requirements and Qualifications

• What We Need to See

• • 6+ years of experience in embedded systems, platform software, bootloader, or BSP development.
• • Strong familiarity with Arm architecture, including exception levels, MMU/cache, GIC, SMP, secure/non-secure world, and boot flow.
• • Hands-on experience with Arm SoC bring-up, with the ability to analyze issues from datasheets, TRMs, and schematics and complete platform initialization.
• • Proficiency in bare-metal C development, linker scripts, startup code, memory maps, and low-level debugging workflows.
• • Practical experience porting and debugging TF-A, U-Boot, Linux kernel, or Device Tree.
• • Familiarity with Arm PSCI, power management, CPU hotplug, suspend/resume, or secure firmware mechanisms.
• • Ability to read hardware specifications and communicate effectively with hardware teams on register settings, clock/reset, power domains, and boot strap behavior.
• • Strong problem-solving skills, cross-functional collaboration skills, and the ability to read English technical documentation.
