Job Description

Your responsibilities

We are looking for a Software Engineer or Computer Scientist with a keen interest in modern memory and interconnect architectures for high-performance computing. In this role, you will work as part of a small, highly motivated team to develop cutting-edge solutions for real-time data processing in the CMS Level-1 trigger system.

Responsibilities:

• Develop an online processing solution for the CMS Level-1 trigger data as part of a highly motivated team.
• Contribute to the conception and design of a prototype distributed processing system utilizing high-speed, high-capacity CPU-to-device and CPU-to-memory connections.
• Collaborate with Micron Technologies Inc. to demonstrate a prototype system architecture based on a shared memory pool, leveraging system-level and device-level cache-coherent protocols (e.g., CXL).
• Implement near-memory compute data processing, including FPGA code that interacts with the memory.
• Develop the system-level software and test suite for the prototype system.
• Work closely with physicists and engineers to design and demonstrate an online infrastructure capable of handling high-rate, high-volume data streams, ensuring scalability for the upgraded CMS experiment in 2029.

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world’s largest and most complex scientific instruments, they study the basic constituents of matter – fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.

Diversity has been an integral part of CERN’s mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
