Offer Description

Your responsibilities

We are excited to invite a motivated Network System Engineer to join our team and contribute to innovative projects. This role offers a unique opportunity to work with state-of-the-art networking equipment and help shape the future DAQ (Data Acquisition) system for the CMS experiment at CERN.

CMS, one of two general-purpose particle physics experiments at CERN’s Large Hadron Collider (LHC), relies on a sophisticated DAQ system to aggregate and process collision data. Looking ahead to the High Luminosity LHC upgrade (2029), you’ll help design a high-speed Ethernet-based network capable of managing 1,000 100Gb/s sources, aggregating to 200 nodes at 400Gb/s, and forwarding data to thousands of processing nodes.

If you’re passionate about networking and want to make a lasting impact, we’d love to hear from you!

Key Responsibilities:

• Work with Cutting-Edge Network Equipment: Gain hands-on experience with state-of-the-art network technology and contribute to the design of the future DAQ network system.
• Install and Maintain the 400GE Test System: Set up and support the 400GE test system for the next-generation DAQ network.
• Perform Network Testing and Equipment Qualification: Conduct tests and qualify equipment to ensure compliance with DAQ requirements.
• Advance Network Monitoring Systems: Maintain and enhance both current and future network monitoring for seamless operations.
• Support Daily Operations: Perform regular monitoring and inspections to keep the data network at peak performance.
• Develop Tools for Network Analysis: Create and maintain tools for network measurement and performance analysis using C and Python.
• Collaborate and Share Expertise: Present results and collaborate within CERN and across the wider community.
• Enthusiasm for learning new technologies and a collaborative approach to problem-solving
• Knowledge of communication technologies and protocols, including network switching, routing, DHCP, and DNS…
• Proficiency in the Linux operating system, particularly in network configuration and the ability to run network testing
• Experience in analyzing and debugging network systems
• Proficiency in C programming; experience with Python is a plus
• Previous experience with High-Performance Computing (HPC) or DAQ systems is a plus
• Relevant certifications in networking or telecommunications is a plus
• Experience with containers (e.g. Docker, Kubernetes) is a plus
• Understanding of the Linux kernel is a plus
• Fluent in English, the ability to work in French would be an advantage.
