Your responsibilities

Join the BE-CSS-CPA team of experienced software engineers and work on our new cutting edge big data processing and analysis platform!
This platform will extend UCAP, our real-time stream processing platform, and combine it with NXCALS, our petabyte-scale offline data storage and analysis system.

As a Software Engineer in our team you will:

• Carry out hands-on research on open-source data processing frameworks such as Spark Structured Streaming, Apache Beam, Kafka Streams, and on modern Kubernetes-based deployment solutions such as Knative and OpenFaaS;
• Design, implement, and optimize a high-performance and scalable data analysis platform using Java, based on your research, together with your new colleagues;
• Work closely with accelerator physicists and equipment specialists to design tailored and user-friendly libraries, APIs and configuration facilities, enabling this user community to quickly and easily develop and deploy both traditional and ML algorithms written in Python and Java.

Your profile

Skills

• Experience as a Backend Software Engineer or similar role:
  • Proficiency in Core Java and its ecosystem;

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.

We are on a Quest. A Journey into discovery like no other. Bring your expertise to our unique work and develop your knowledge and skills at pace. Join world-class subject matter experts on unique projects, in a Quest for greater knowledge and deeper understanding.
