you’ll do\nContribute to Lustre architecture and lead implementation of new features across core subsystems including MDS/OSS, LDLM, DNE, DoM, FLD, layout, snapshot, quota, security, and recovery\n\nWrite high-performance, production-grade code across the Lustre kernel module, user-space utilities, and supporting libraries\n\nOwn the full development lifecycle for major features, from design and coding through testing, performance tuning, and upstream patch submission\n\nImprove scalability for multi-petabyte Lustre environments, including metadata performance, I/O path optimization, and integration with modern interconnects and storage fabrics\n\nModernize Lustre internals through kernel API updates, locking improvements, RDMA enhancements, and cloud/container-oriented capabilities\n\nPrototype and evaluate emerging technologies such as NVMe-oF, CXL, and other next-generation storage approaches for potential Lustre integration\n\nStrengthen regression, stress, and performance validation using tools such as IOR, mdtest, fio, and custom Lustre test tooling\n\nPerform deep code-level performance analysis using Lustre tracing tools, perf, lockstat, and kernel profilers\n\nWork closely with Principal Engineers, hardware teams, and application owners to translate real workload needs into practical Lustre improvements\n\nMentor other developers and contribute design docs, technical guides, and engineering reviews\n\nWhat we’re looking for\n7+ years of progressive, hands-on Lustre software development experience\n\nA strong track record of meaningful contributions to the Lustre codebase in production or open-source environments\n\nDemonstrated success designing, implementing, and upstreaming Lustre features that made it into major releases\n\nDeep understanding of Lustre internals, including MDS/OSS architecture, LDLM locking and recovery, journaling, DNE, DoM, FLD, layout, quota, and security\n\nExpert-level C programming and strong Linux kernel development experience\n\nStrong knowledge of distributed systems, parallel file systems, and high-performance I/O\n\nExperience with Lustre build, development, and debugging tooling such as lctl, llstat, strace, perf, and kernel tracers\n\nPython and/or Bash skills for tooling and automation\n\nBachelor’s or Master’s degree in Computer Science, Computer Engineering, or a related field\n\nClear written and verbal communication skills, with the ability to explain complex technical concepts effectively\n\nNice to have\n7+ years in HPC or storage software development\n\nVisible contributions to the Lustre open-source community, including accepted patches, LUG participation, or public technical talks\n\nExperience running or developing Lustre in cloud environments such as AWS FSx for Lustre, Azure Lustre, or custom cloud deployments\n\nFamiliarity with adjacent systems such as Ceph, DAOS, BeeGFS, WekaIO, or GPFS\n\nExposure to RDMA, NVMe-oF, CXL, computational storage, or AI/ML I/O workloads\n\nConference presentations, technical publications, or other public engineering contributions\n\nYou’ll likely be a strong fit if you…\nHave built inside Lustre itself, not just around it\n\nEnjoy solving hard kernel, performance, and distributed systems problems\n\nCare about code quality, upstream contribution, and long-term architectural impact\n\nWant to work on infrastructure that operates at real scale under real performance constraints\n\nThis role is probably not the right fit if you…\nHave mainly supported or administered Lustre rather than developed it\n\nCome from general storage or kernel backgrounds without clear Lustre code contribution history\n\nPrefer high-level application engineering over low-level systems and kernel
