Sr/Staff Lustre Engineer

What you’ll doContribute to Lustre architecture and lead implementation of new features across core subsystems including MDS/OSS, LDLM, DNE, DoM, FLD, layout, snapshot, quota, security, and recoveryWrite high-performance, production-grade code across the Lustre kernel module, user-space utilities, and supporting librariesOwn the full development lifecycle for major features, from design and coding through testing, performance tuning, and upstream patch submissionImprove scalability for multi-petabyte Lustre environments, including metadata performance, I/O path optimization, and integration with modern interconnects and storage fabricsModernize Lustre internals through kernel API updates, locking improvements, RDMA enhancements, and cloud/container-oriented capabilitiesPrototype and evaluate emerging technologies such as NVMe-oF, CXL, and other next-generation storage approaches for potential Lustre integrationStrengthen regression, stress, and performance validation using tools such as IOR, mdtest, fio, and custom Lustre test toolingPerform deep code-level performance analysis using Lustre tracing tools, perf, lockstat, and kernel profilersWork closely with Principal Engineers, hardware teams, and application owners to translate real workload needs into practical Lustre improvementsMentor other developers and contribute design docs, technical guides, and engineering reviewsWhat we’re looking for7+ years of progressive, hands-on Lustre software development experienceA strong track record of meaningful contributions to the Lustre codebase in production or open-source environmentsDemonstrated success designing, implementing, and upstreaming Lustre features that made it into major releasesDeep understanding of Lustre internals, including MDS/OSS architecture, LDLM locking and recovery, journaling, DNE, DoM, FLD, layout, quota, and securityExpert-level C programming and strong Linux kernel development experienceStrong knowledge of distributed systems, parallel file systems, and high-performance I/OExperience with Lustre build, development, and debugging tooling such as lctl, llstat, strace, perf, and kernel tracersPython and/or Bash skills for tooling and automationBachelor’s or Master’s degree in Computer Science, Computer Engineering, or a related fieldClear written and verbal communication skills, with the ability to explain complex technical concepts effectivelyNice to have7+ years in HPC or storage software developmentVisible contributions to the Lustre open-source community, including accepted patches, LUG participation, or public technical talksExperience running or developing Lustre in cloud environments such as AWS FSx for Lustre, Azure Lustre, or custom cloud deploymentsFamiliarity with adjacent systems such as Ceph, DAOS, BeeGFS, WekaIO, or GPFSExposure to RDMA, NVMe-oF, CXL, computational storage, or AI/ML I/O workloadsConference presentations, technical publications, or other public engineering contributionsYou’ll likely be a strong fit if you…Have built inside Lustre itself, not just around itEnjoy solving hard kernel, performance, and distributed systems problemsCare about code quality, upstream contribution, and long-term architectural impactWant to work on infrastructure that operates at real scale under real performance constraintsThis role is probably not the right fit if you…Have mainly supported or administered Lustre rather than developed itCome from general storage or kernel backgrounds without clear Lustre code contribution historyPrefer high-level application engineering over low-level systems and kernel workLocationSanta ClaraEmployment TypeFull timeLocation TypeHybridDepartmentDepartmentEngineeringEngineeringInfinia Engineering
