Staff Software Engineer – Host & Secure Compute Software - Cork, Ireland

Host & System Software Development Design, implement, and optimize Linux user‑space and kernel‑adjacent drivers and libraries in modern C++. Lead development of host software stacks supporting high‑performance AI inference and secure compute workloads. Drive API design, multi‑threaded systems, and scalable software architectures. Own feature development, integration, and bring‑up across hardware and software boundaries. Architect and develop unit, integration, and system‑level tests for CI environments. Establish best practices for testability, automation, and long‑term maintainability. Integrate host software with Trusted Execution Environments (TEEs) including Secure VMs (CVM) and Software‑Isolated VMs (SIVM). Enable secure PCIe device assignment, SR‑IOV, and container/VM‑based workloads. Implement and support device attestation, lifecycle management, and secure interface configuration. Collaborate on PCIe firewall, memory protection, and register isolation features. Performance, Debug & Bring‑Up Provide technical leadership across mixed hardware/software teams. Drive design reviews, influence system architecture, and mentor senior engineers. Work closely with hardware, firmware, hypervisor, security, and cloud teams to deliver end‑to‑end solutions. Support customer deployments and resolve complex system‑level issues. Extensive experience with Linux system software development in modern C/C++. Strong background in Linux user‑space development, API design, and multi‑threading / synchronization. Solid understanding of Linux internals, kernel concepts, drivers, and system bring‑up. Experience with UML, OO design, and large‑scale software architecture. Strong knowledge of SoC architecture (cores, caches, memory hierarchy, interconnects, I/O). Experience with source code and configuration management (git required). Proven ability to work at low‑level implementation detail while maintaining system‑level perspective. Excellent written and verbal English communication skills. Comfortable operating in a high‑caliber, cross‑disciplinary engineering environment. Typically 6+ years of relevant industry experience in system or platform software. Demonstrated ownership of complex subsystems across multiple releases. Ability to set technical direction, not just execute tasks. Track record of influencing architecture, quality, and engineering standards. These are not strictly required, but will significantly differentiate candidates: Experience with secure compute, confidential computing, or TEEs. Familiarity with virtualization and container technologies (KVM, Docker, SR‑IOV). Knowledge of cryptographic protocols, device security, and attestation mechanisms. Experience optimizing AI/ML inference workloads on system software stacks. Proficiency in Python for tooling, testing, or automation. Experience with C/C++ unit testing frameworks (e.g., gtest). Exposure to cloud technologies, middleware, and protocols. Working knowledge of PCIe 3.0+. Linux system administration experience. Contributions to open‑source kernel or confidential computing projects. Bachelor's degree in Engineering, Information Systems, Computer Science, or related field and 4+ years of Software Engineering or related work experience. OR Master's degree in Engineering, Information Systems, Computer Science, or related field and 3+ years of Software Engineering or related work experience. OR PhD in Engineering, Information Systems, Computer Science, or related field and 2+ years of Software Engineering or related work experience. 2+ years of work experience with Programming Language such as C, C++, Java, Python, etc. References to a particular number of years experience are for indicative purposes only. Applications from candidates with equivalent experience will be considered, provided that the candidate can demonstrate an ability to fulfill the principal duties of the role and possesses the required competencies.
