Staff Software Engineer

Staff Software Engineer – Host & Secure Compute Software - Ireland - EU Relocation Offered We are seeking a Staff Software Engineer to lead the development of Linux-based system software for next-generation data centre and secure computing platforms. This is a hands-on technical leadership role focused on host-side software, drivers, system integration and performance optimisation for high-performance AI inference accelerators and secure computing solutions. Key Responsibilities - Design, develop and optimise Linux user-space software, libraries and kernel-adjacent drivers using modern C++. - Lead development of host software stacks supporting AI inference and secure computing workloads. - Design and implement unit, integration and system-level testing frameworks for continuous integration environments. - Lead functional testing, performance validation and debugging of host software and drivers. - Integrate host software with Trusted Execution Environments (TEEs), confidential virtual machines and software-isolated virtual machines. - Enable secure PCIe device assignment, SR-IOV and container- or VM-based workloads. - Optimise software for high-performance AI inference and low-latency workloads. - Lead design reviews, influence engineering standards and mentor experienced engineers. - Collaborate with hardware, firmware, hypervisor, security and cloud engineering teams. - Support customer deployments and resolve complex system-level issues. Required Experience - Typically 6+ years of relevant industry experience in system software, platform software or closely related engineering disciplines. - Extensive hands-on experience developing Linux-based system software in C and/or modern C++. - Strong Linux user-space development skills, including API design, multithreading and synchronisation. - Solid understanding of Linux internals, kernel concepts, drivers and system bring-up. - Knowledge of SoC architecture, including processor cores, caches, memory hierarchy, interconnects and I/O. - Experience with object-oriented design, UML and large-scale software architecture. - Proficiency with Git and software configuration management. - Ability to work at implementation level while maintaining a broader system architecture perspective. Desirable Experience - Confidential computing, secure computing or Trusted Execution Environments. - Virtualisation technologies, including KVM, Docker, SR-IOV and confidential virtual machines. - Cryptographic protocols, device security and attestation mechanisms. - AI/ML inference optimisation and accelerator software stacks. - Python-based tooling, test automation and scripting. - C/C++ testing frameworks, such as GoogleTest (gtest). - PCIe 3.0 or later, Linux system administration and cloud infrastructure. - Middleware, communication protocols or open-source Linux kernel contributions. - Experience working across hardware, firmware, hypervisor and software boundaries.
