Linux/OSS Security Software Engineer — Industrial High-end Processors

Job Title

Linux/OSS Security Software Engineer — Industrial High-end Processors

Role Summary

Develop Linux and open-source software for Renesas RZ high-end processors, focusing on device drivers, platform porting, and security features for industrial and embedded products. Work with LSI design teams and external OSS communities to deliver production-ready software and maintain inner-source artifacts.

This position operates on a hybrid schedule (two remote days per week; core office days Tue–Thu) and requires collaboration across global teams and open-source stakeholders.

Experience Level

Mid-level — typically 5+ years embedded software development experience and at least 3 years working with Linux kernel, device drivers, or related areas.

Responsibilities

Primary responsibilities depend on experience and specialization; typical duties include:

• Design and implement device drivers for new hardware platforms.
• Design and develop hardware-based security features (e.g., secure boot, crypto engines).
• Develop and maintain common Linux-related software for high-end processors (Linux kernel, TF-A, U-Boot, OP-TEE) and manage these artifacts as inner-source.
• Evaluate and integrate OSS for industrial networking (e.g., OPC UA) and other platform components.
• Engage with OSS communities and internal/external stakeholders: submit patches, provide technical proposals and support.
• Set up and maintain Yocto Project build environments (recipe creation and maintenance).
• Package proprietary libraries for Debian/Ubuntu targets.
• Manage CVE tracking and patching policies; apply mitigations and fixes.
• Define software maintenance plans and improve processes, including automation and quality measures.
• Perform technology research and prototyping for next-generation products.

Requirements

Concise list of required and preferred qualifications.

• 5+ years embedded software development experience able to implement and debug from hardware specifications independently.
• 3+ years experience in one or more: Linux kernel, device drivers, graphics, video codecs, security, or industrial networking functions.
• Basic knowledge of open-source licenses (GPL, MIT, BSD types).
• Effective communication skills with customers and internal/external stakeholders.
• Willingness to work using English and collaborate internationally.

• Experience with Yocto Project and recipe maintenance.
• Knowledge of Arm (Cortex-A/M/R, TrustZone) or RISC-V architectures; assembly programming experience on those platforms.
• Experience with embedded security topics (secure boot, cryptography, SELinux) and CVE response.
• Debugging experience on development boards using ICE tools.
• Contributions to open-source communities.
• Experience with CI/CD tools (GitLab, Jenkins) and virtualization/hypervisor technologies.
