CERN - European Organization for Nuclear Research

Company DescriptionJob Description

Your responsibilities

Are you a curious and motivated computing graduate, eager to contribute to a global scientific infrastructure? Join CERN and help shape the future of distributed computing by improving how we monitor and understand the use of computing resources across the Worldwide LHC Computing Grid (WLCG), a global collaboration of more than 150 computing centers in more than 40 countries, serving cutting-edge particle physics.

As a member of the CERN IT department's Technical Coordination group, you will contribute to the development, deployment, and validation of next-generation accounting and configuration systems. Your work will ensure that resource usage across the grid is accurately tracked, anomalies are automatically detected, and data is readily available for analysis and reporting.

In this position, you will:

• Contribute to the development, integration, and operation of modern, extensible accounting systems across distributed computing sites, in collaboration with international partners.
• Design and implement anomaly detection workflows to help identify data inconsistencies or infrastructure issues, leveraging classic and machine learning techniques.
• Help streamline the validation and monitoring of accounting data through automation.
• Learn and apply DevOps practices in a containerized, Kubernetes-based environment, using tools such as GitLab CI/CD. Collaborate with a diverse community of researchers, developers, and operations experts around the globe.

This is a unique opportunity to work at the intersection of scientific computing, data engineering, and infrastructure automation, supporting the global computing services that enable discoveries at the LHC.

Your profile

Skills:

• Programming experience in Python and solid knowledge of Linux environments.
• Familiarity with container and orchestration technologies, such as Docker, Kubernetes, and OpenShift.
• Experience with search and monitoring tools, such as OpenSearch, Grafana, or InfluxDB.
• Experience with data processing or streaming tools, such as Apache Spark or Kafka.
• Exposure to anomaly detection or ML techniques.
• Spoken and written English, with a commitment to learn French.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• By the application deadline, you have a maximum of two years of professional experience since graduation in Software engineering (or a related field) and your highest educational qualification is either a Bachelor's or Master's degree.
• You have never had a CERN fellow or graduate contract before.
• Applicants without University degree are not eligible.
• Applicants with a PhD are not eligible.

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.
