Overview
If you’ve spent years deep in the Lustre codebase — not just administering Lustre systems, but actually designing, building, optimizing, and upstreaming features — this is a chance to work on one of the most demanding storage engineering problems in the market.
We’re looking for a hands-on Lustre Engineer to help shape the next generation of high-performance, enterprise-ready Lustre capabilities. This role is for someone who is equally comfortable working in kernel-space C, analyzing performance bottlenecks in large-scale deployments, and collaborating with other senior engineers to evolve Lustre architecture for modern infrastructure.
Job Description
What you’ll do
- Contribute 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
- Write high-performance, production-grade code across the Lustre kernel module, user-space utilities, and supporting libraries
- Own the full development lifecycle for major features, from design and coding through testing, performance tuning, and upstream patch submission
- Improve scalability for multi-petabyte Lustre environments, including metadata performance, I/O path optimization, and integration with modern interconnects and storage fabrics
- Modernize Lustre internals through kernel API updates, locking improvements, RDMA enhancements, and cloud/container-oriented capabilities
- Prototype and evaluate emerging technologies such as NVMe-oF, CXL, and other next-generation storage approaches for potential Lustre integration
- Strengthen regression, stress, and performance validation using tools such as IOR, mdtest, fio, and custom Lustre test tooling
- Perform deep code-level performance analysis using Lustre tracing tools, perf, lockstat, and kernel profilers
- Work closely with Principal Engineers, hardware teams, and application owners to translate real workload needs into practical Lustre improvements
- Mentor other developers and contribute design docs, technical guides, and engineering reviews
What we’re looking for
- 7+ years of progressive, hands-on Lustre software development experience
- A strong track record of meaningful contributions to the Lustre codebase in production or open-source environments
- Demonstrated success designing, implementing, and upstreaming Lustre features that made it into major releases
- Deep understanding of Lustre internals, including MDS/OSS architecture, LDLM locking and recovery, journaling, DNE, DoM, FLD, layout, quota, and security
- Expert-level C programming and strong Linux kernel development experience
- Strong knowledge of distributed systems, parallel file systems, and high-performance I/O
- Experience with Lustre build, devel
