Staff Engineer, LustreFS & Distributed Storage

DDN; North Carolina; Ibrido; USD 150.000 - 190.000; Tempo pieno

Descrizione del lavoro

DDN is actively seeking a Staff Engineer to lead hands-on design, debugging and optimization of LustreFS and related stack components on Linux-based systems. This senior technical role emphasizes cross-team collaboration across engineering, QE, support and release, with a focus on reliability and operational excellence in high-performance storage environments.

The candidate should bring 10+ years of experience in distributed storage and systems software, deep C programming skills, and strong

Competenze

• 10+ years of experience in systems software, distributed systems, storage, Linux kernel or filesystem engineering.
• Strong experience in LustreFS development, support or performance engineering with depth in at least one major subsystem.
• Strong C programming and Linux systems debugging skills.
• Working knowledge of Linux kernel internals, filesystem semantics, networking and performance analysis.
• Experience with LNet and/or high-performance transports such as RDMA, InfiniBand, RoCE or TCP-based storage networking.
• Ability to debug and resolve issues spanning multiple layers including client, server, network and backend storage.
• Strong collaboration skills and the ability to work across functions in a fast-moving engineering environment.

Mansioni

• Design, develop and debug LustreFS features, fixes and enhancements across subsystems such as llite, MDS/MDT, OSS/OST, LDLM and LNet.
• Investigate customer and scale-related defects, drive root-cause analysis and implement high-quality fixes with strong attention to correctness and maintainability.
• Contribute to performance tuning, failure analysis and reliability improvements for large-scale Lustre deployments.
• Participate actively in code reviews, design reviews and subsystem discussions, bringing rigor to testing and operational readiness.
• Work closely with QE and support to reproduce issues, improve diagnostic data quality and increase coverage for high-risk failure scenarios.
• Help document subsystem behavior, debugging approaches, known failure patterns and operational best practices.
• Use AI-assisted tools where appropriate to speed up issue triage, summarize logs, improve code understanding and capture reusable lessons learned.
