Linux, OSS, and Security Software Engineer for Industrial high-end processors

Job Description 【Backgroud】 The application scope of industrial processors is rapidly expanding, ranging from edge AI devices to factory equipment and data center applications. In this context, ensuring cybersecurity for systems that include embedded devices has become a significant societal challenge in sectors such as manufacturing and healthcare. As a result, embedded products for industrial use are required to achieve both advanced functionality and a high level of security. Expanding product capabilities through the use of open source software and applying the latest security technologies to products have become key priorities. In this position, you will be responsible not only for device driver development and porting of existing software, but also for addressing emerging industrial standards and advanced security technologies. You will drive these initiatives as part of a global development team, working in collaboration with open source communities. You will gain hands-on experience in developing open source technologies, particularly Linux-based platforms, as well as security technologies for embedded systems, and delivering these innovations as products to the market. We are looking for engineers who have a strong interest in these areas and are motivated to contribute to bringing products to market. 【Job Description】 This position is responsible for the design and development of Linux-related software for our industrial high-end processor, RZ series, in collaboration with internal LSI design teams and both domestic and international open source communities. Based on your skills, experience, and area of expertise, you will primarily be assigned to one or more of the following areas: Design and development of device drivers for new hardware Design and development of security features such as hardware-based encryption and secure boot Design and development of common Linux-related software (e.g., Linux kernel, Trusted Firmware-A, U-Boot, OP-TEE) for high-end processor products, as well as management and maintenance of deliverables as InnerSource assets Integration and evaluation of open source software for industrial networking functions, such as OPC UA Technical discussions, proposals, and support with internal and external stakeholders, including open source communities, as well as contribution of patches to those communities Development and maintenance of build environments using the Yocto Project (e.g., recipe development and maintenance) Package development for proprietary libraries for Ubuntu and Debian Management of vulnerability information (CVE: Common Vulnerabilities and Exposures), formulation of patching strategies, and implementation of countermeasures Planning and management of software maintenance, as well as process improvements and automation to ensure product quality Technology research, prototyping, and evaluation for next-generation products*The full details regarding your position scope as well as any future potential changes in work location and job scope will be provided during the interview process.
