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.
