You'll be responsible for designing and implementing OS-level security controls, from kernel hardening to runtime protection, ensuring our systems can withstand sophisticated attacks while maintaining the performance required for AI model training. This is a hands-on role where you'll work with cutting-edge hardware and implement novel security solutions for environments that don't exist anywhere else in the world. You'll need to balance extreme security requirements with the operational needs of researchers training models at unprecedented scale., * Design and implement hardened OS configurations for AI workloads across diverse hardware platforms * Minimize attack surfaces by removing as many unnecessary components as possible from kernelspace and userspace * Develop kernel security policies using SELinux, AppArmor, and custom Linux Security Modules and runtime enforcement mechanisms * Implement and maintain full-disk encryption solutions for diverse storage systems * Build security infrastructure for AI systems, research environments, and production services * Create OS-level attestation and integrity monitoring systems * Apply security patches, develop patches for custom kernel modules, and kernel hardening configurations * Design secure boot processes and trusted execution environments * Work with container teams to ensure proper workload isolation at the kernel level * Design privilege separation and mandatory access control policies * Implement secure update mechanisms for OS components * Build tooling for security configuration management and compliance verification * Serve as a subject matter expert for OS security questions and designs ## Related Videos - [Enhancing Workload Security in Kubernetes](https://www.wearedevelopers.com/videos/356-enhancing-workload-security-in-kubernetes) - [You can’t hack what you can’t see](https://www.wearedevelopers.com/videos/41-you-can-t-hack-what-you-can-t-see) - [10M Data Records Lost, Underwater Computing, and Psychedelic Fish - Matthias Geniar](https://www.wearedevelopers.com/videos/1908-10m-data-records-lost-underwater-computing-and-psychedelic-fish-matthias-geniar) - [Surviving the Vulnpocalypse: Open Source and Supply Chain Security in a Post Mythos World](https://www.wearedevelopers.com/videos/100279-surviving-the-vulnpocalypse-open-source-and-supply-chain-security-in-a-post-mythos-world) - [Develop on Windows, Deploy on Red Hat Enterprise Linux](https://www.wearedevelopers.com/videos/1600-develop-on-windows-deploy-on-red-hat-enterprise-linux) - [For the Cars and the Curious: Android Drift](https://www.wearedevelopers.com/videos/499-for-the-cars-and-the-curious-android-drift) ## Related Articles - [9 Ways to Make Money Hacking](https://www.wearedevelopers.com/magazine/333-9-ways-to-make-money-hacking) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs)
