Job description:

DDN Storage and the largest HPC Customers in the world have been working together to enable large scale parallel filesystems to power large scale compute clusters for many years.

This partnership revolves mainly around High-Performance Storage and Parallel File Systems, such as Lustre, improving and developing cutting edge technologies for HPC and Ai.

We are seeking to hire a Field Storage Engineer with File System development skills.

Please note applicants must have French citizenship to comply with government's security clearance procedure.

The Field Storage Engineer & Developer is a “hybrid” role with an equal time distribution of:

1. System Engineering for the Field:

• Install, optimize DDN’s High-Performance Storage “EXAScaler” solutions (powered by Lustre File System) for Prospects and Customers in France, and possibly Europe and Middle-East when required.
  
  
• Train Partner and End-User on the EXAScaler Solution that has been deployed.
  
  
• Benchmark the said EXAScaler Storage Solution with industry-standard HPC I/O tools such as FIO, IOR, IOZONE, MDT and across the Cluster of HPC / Ai CPU-GPU Compute Nodes.

• Troubleshoot, when necessary, I/O errors at the file level and at the block level.

• The applicant will be interacting with several DDN Departments like Presales, Global Education, L1/L2 Support and Storage / Parallel File System Subject Matter Experts based in the Field.

• The applicant will also engage End-User and when necessary, Partners and Industry Representatives (such as Servers Manufacturers, GPU Vendors, etc.).

• Applicants will receive technical training from DDN Storage experts.

2. File System development for one specific large HPC Customer – The Client:

• For this section of the work, the applicant's will be in direct contact with The Client’s administration team.

• The role here will be to understand, troubleshoot and provide technical support for the various Lustre filesystems in production at The Client premises.

• The applicant will also be required to channel technical feedback and user stories between The Client and DDN to improve the products (hardware and software).

• This will require the applicant to dive into the Lustre filesystem, an industry standard parallel filesystem developed by Whamcloud (a division of the DDN group).

• Whamcloud, a DDN Division, is always releasing Lustre software patches into the Master Branch. The applicant will back-port select patches into The Client’s Lustre distribution.

• Over time, once fluent with back-porting Lustre patches, the applicant will contribute to Whamcloud & The Client Lustre code development efforts for new features or bug fixes.

• Applicants will receive technical training from DDN and Whamcloud experts.

Required Skills and experience:

• Rigorous reporting and communication, both in the French and English languages.
• Experience with the Linux kernel and understanding of certain subsystems (such as the I/O schedulers or network stack).
• Experience in software development like C/C++ or RUST, ideally with Linux Kernel development previous experience.
• Experience of scripting languages such as Python and Bash.
• Knowledge of high-speed interconnect (such as InfiniBand) and TCP/IP networking, not mandatory but appreciated.
• Experience with the Lustre filesystem is appreciated.
• Knowledge and/or experience of storage systems is a plus.
