Renesas is seeking an accomplished Software Engineerto lead the development and delivery of embedded operating system software and middleware for the Renesas RZ family of ARM-based microprocessors. This role owns the end-to-end software strategy across multiple operating systems—including Linux, Zephyr RTOS, FreeRTOS, and Azure RTOS—as well as the middleware stack that enables RZ platforms across industrial, IoT, automotive, and consumer markets.
The ideal candidate brings deep technical expertise in embedded systems, the hardware/software interface, and open-source development practices, combined with proven leadership and the ability to drive cross-functional collaboration with SoC architects, product managers, and external partners.
Job Description
Technical Leadership & Architecture
Define and own the operating system roadmap and strategy for the Renesas RZ product family, including build-vs-buy decisions, internal development priorities, and partner-driven ports.
Oversee the enablement, porting, and upstreaming of Linux, Zephyr RTOS, FreeRTOS, and Azure RTOS across the RZ SoC portfolio (e.g., RZ/G, RZ/V, RZ/A, RZ/T series).
Drive the architecture, development, and maintenance of middleware components—including but not limited to graphics frameworks, networking stacks, security libraries, file systems, connectivity (Wi-Fi, Bluetooth), motor control libraries, and multimedia codecs.
Collaborate closely with SoC architects and hardware teams to ensure silicon designs are well-supported by software, influencing decisions around IOMMU, DMA, interrupt controllers, boot ROM interfaces, and peripheral IP.
Ensure robust Board Support Package (BSP) development, device tree enablement, and driver development across all supported operating systems.
Lead upstream contribution strategies to Linux kernel, Zephyr Project, and other open-source communities, maintaining active maintainer/contributor relationships.

Embedded OS Expertise: Deep hands-on experience with at least two of the following:
Linux kernel development (driver development, BSP bring-up, upstreaming)
Hardware/Software Interface: Strong understanding of ARM Cortex-A and Cortex-R/M architectures, SoC boot flows, JTAG/debug interfaces, memory-mapped peripherals, and hardware datasheet interpretation.
Middleware: Experience with embedded middleware including graphics (Wayland, LVGL), networking (TCP/IP, TLS), connectivity (Bluetooth, Wi-Fi), storage, and security components.
Open-Source: Demonstrated track record of upstream contributions and compliance management (GPL/BSD/MIT/Apache licensing).
Tools & Infrastructure: Proficiency with Git, Yocto/OpenEmbedded, Buildroot, Jenkins or equivalent build systems, and Docker/containerized build environments.
Preferred Qualifications
Familiarity with functional safety standards (ISO 26262, IEC 61508) as applied to embedded software.
Experience with AI/ML acceleration stacks on embedded processors (e.g., edge AI inference runtimes).
Knowledge of motor control algorithms and real-time control systems.
Prior experience working with or within semiconductor companies on MPU/MCU software enablement.
Active standing in open-source communities (e.g., kernel maintainer, Zephyr contributor).
Experience working with geographically distributed teams.
