Bull is a story. One with a century of European innovation and a working environment where experts design powerful, sustainable, and sovereign digital solutions, enabling states and industries to retain full control over their data and their AI.

Bull is also thousands of engineers, researchers and passionate tech people shaping the future of high-performance computing, AI, and quantum technologies.

Every day, our teams push the boundaries of what is technologically possible – from next-generation HPC architectures to exascale supercomputers – supported by world-class R&D, more than 1,600 patents, and unique end-to-end capabilities spanning hardware design, software engineering, data science and quantum research.

We are a people-centric, innovation-driven company, where collaboration spans Europe, the Americas and India. We share a common vision of a responsible and sustainable innovation that delivers concrete impact for our customers.

 

Job context

 

The BigData & Security (BDS) entity of the ATOS group develops professional servers under the Bull brand for the cloud and big data market on the one hand, and for the scientific computing (or HPC) market on the other… The components and the manufacturing / assembly processes implemented in the servers are subject to constraints & normative requirements for which compliance must be justified.

Attached to the system quality and performance team within the R&D Server Design department, we are recruiting a Performance Engineer who brings together performance expertise at server levels. 

 

Activities

In close collaboration with the Project Manager and development teams, you intervene transversely and closely within server development projects. Your main missions are:

· Ensure a technical watch on the latest tools and benchmarks.

· Define, in coordination with the management team, the strategies/methods and needs for each product.

· In conjunction with R&D teams, ensure that all stages of the products (EVT / DVT / PVT) the performance expected are met.

o Verify Performance at component level of the system (CPU / GPU / Interconnect / Disk / Memory / Interconnect)

· Drive the optimization of the systems (BIOS / Hardware)

· Develop / improve our current set of tools to help supports our goals.

· Publish official results of our systems with SPEC.

o We currently publish SPEC CPU 2017 results.

· Drive the Performance team

 

Required profile
