Join the RISC-V Revolution! 

We are looking for a senior hands-on engineer to lead Zephyr RTOS architecture and platform enablement for MIPS RISC-V based MCU and embedded compute products. This role combines deep low-level development with technical ownership, upstream engagement, mentoring, and cross-functional delivery. 

Key Responsibilities 

• Own the Zephyr enablement architecture and technical roadmap across MIPS RISC-V processors, SoCs, FPGA platforms, and virtual development platforms. 

• Lead porting and platform bring-up covering boot flow, exception and interrupt handling, timers, SMP where applicable, memory architecture, devicetree, Kconfig, and build integration. 

• Define scalable BSP, SoC, board, and driver architecture aligned with Zephyr conventions and upstream-quality expectations. 

• Design and review device drivers, middleware integration, samples, tests, and production-quality SDK deliverables. 

• Lead complex debugging across kernel, toolchain, architecture, hardware, and driver boundaries using emulation, FPGA, and silicon. 

• Establish automated build and regression strategy using Zephyr testing infrastructure and CI/CD systems. 

• Drive upstream contributions, technical discussions, reviews, and maintenance strategy within the Zephyr ecosystem. 

• Work closely with CPU architecture, SoC, FPGA, tools, validation, safety, and customer teams; convert product requirements into executable software plans. 

• Mentor engineers, raise engineering quality, and provide technical direction without losing hands-on ownership. 

Ideally, You'll Have 

• 8+ years of embedded software development experience, with substantial hands-on work in C and low-level platform software. 

• Deep Zephyr RTOS expertise across kernel configuration, architecture or SoC ports, devicetree, Kconfig, west/CMake, board support, drivers, and test infrastructure. 

• Strong understanding of RTOS internals, concurrency, interrupt architecture, memory management, boot flows, multicore systems, and real-time performance. 

• Proven experience leading complex BSP, SDK, RTOS, or silicon-enablement programs from architecture through release. 

• Experience with bare-metal firmware, first-board or first-silicon bring-up, device drivers, and hardware/software debugging. 

• Strong debugging capability using GDB, OpenOCD, Segger J-Link, Lauterbach, trace tools, and hardware logs. 

• Experience with CI/CD, test automation, Python or shell scripting, code review, release quality, and software configuration management. 

• Ability to communicate architecture and execution trade-offs clearly to hardware, software, program, and customer stakeholders. 

Strong Differentiators 

• Zephyr maintainer-level expertise or meaningful upstream contribution history. 

• RISC-V architecture expertise, including privilege modes, interrupts, timers, SMP, cache or memory-ordering considerations, and toolchain integration. 

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

• Experience enabling RTOS software on pre-silicon models, FPGA, and production silicon. 

• Exposure to functional safety or secure software development for automotive, industrial, or infrastructure applications. 

What You'll Get 

• A charter to shape Zephyr strategy and execution for a new RISC-V platform. 

• Direct access to CPU architects, platform software, FPGA, validation, and toolchain teams. 

• Visible technical ownership spanning architecture, upstream ecosystem, customer enablement, and release quality. 

• A path to grow as a principal technical contributor or broader technical leader.
