Join the RISC-V Revolution! 

We are looking for hands-on embedded software engineers to develop and enable Zephyr RTOS on MIPS RISC-V based MCU and embedded compute platforms. You will work across board and SoC bring-up, kernel and driver integration, SDK content, testing, and upstream ecosystem contribution. 

What You'll Do 

• Port and enable Zephyr RTOS on new MIPS RISC-V processors, SoCs, FPGA platforms, and virtual development platforms. 

• Develop and maintain board support packages, device-tree descriptions, startup code, interrupt and timer support, and SoC integration layers. 

• Develop or integrate Zephyr device drivers for interfaces and peripherals such as UART, SPI, I2C, GPIO, timers, watchdogs, Ethernet, CAN, and storage. 

• Create reference applications, samples, tests, and SDK documentation that help internal teams and customers adopt the platform. 

• Debug kernel, driver, boot, memory, interrupt, concurrency, and performance issues using emulators, FPGA or silicon platforms. 

• Contribute automated tests to Zephyr test infrastructure and integrate builds and regression execution into CI pipelines. 

• Collaborate with CPU architecture, SoC, FPGA, tools, validation, and customer-facing teams to align software with hardware capabilities. 

• Contribute fixes and features upstream to Zephyr and related open-source projects where appropriate. 

You Should Have 

• 4-6 years of hands-on embedded software development experience. 

• Strong C programming skills, with working knowledge of C++ and embedded assembly. 

• Practical Zephyr RTOS development experience, including kernel configuration, Kconfig, devicetree, west/CMake builds, boards, SoCs, and device drivers. 

• Solid understanding of RTOS concepts: threads, scheduling, interrupts, synchronization, timers, memory management, and inter-process communication. 

• Experience with bare-metal firmware, memory-mapped I/O, low-level drivers, BSPs, and hardware bring-up. 

• Experience using Git and debugging tools such as GDB, OpenOCD, Segger J-Link, or Lauterbach. 

• Python or shell scripting experience for build, test, and validation automation. 

• Ability to read processor, SoC, and peripheral technical documentation and translate it into reliable software. 

Good to Have 

• RISC-V architecture, privilege levels, interrupts, timers, and toolchains. 

• Zephyr upstream contribution or open-source community participation. 

• Experience with networking stacks, Ethernet, TCP/IP, device management, secure boot, firmware update, or MCUboot. 

• Experience with FPGA, pre-silicon models, post-silicon bring-up, or embedded validation. 

• Exposure to functional safety, security, or automotive/industrial embedded systems. 

What You'll Get 

• Direct impact on a new RISC-V software platform and its Zephyr ecosystem. 

• Close collaboration with CPU architects, SoC teams, toolchain engineers, and experienced embedded developers. 

• End-to-end ownership spanning platform bring-up, SDK delivery, validation, and open-source enablement. 

• A flexible growth path toward deep technical specialization or technical leadership.
