Company Description

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.

Job Description

Introduction

Are you a skilled Software Engineer? Do you want to contribute to the unique challenge of making all the CERN particle accelerators function like a gigantic distributed clockwork with nanosecond precision? Then join the timing team in the beam controls group and realize your potential. Take Part!

The CERN accelerator complex is composed of thousands of magnets, accelerating RF cavities, beam measurement instruments and much, much more equipment, which function in a sophisticated, well-coordinated fashion to produce, accelerate and deliver the high energy particle beam to the big physics experiments.

From a computing point of view, this is a huge and complex distributed system with thousands of devices running real-time software, connected by high performance communication networks, and synchronized with nanosecond precision. The so-called Accelerator Timing System coordinates all these devices, just like a conductor coordinates the musicians in a symphonic orchestra.

You will join:

  • The BE Department, responsible for the beam generation, acceleration, diagnostics, controls and performance optimization for the LHC and its injector accelerators.
  • The CO Group, responsible for providing and supporting the controls hardware, software and infrastructure used to operate and maintain these particle accelerators 24 hours a day.
  • The SRC Section: a dynamic and quality-oriented agile team, responsible for the Accelerator Timing System and other mission-critical software for communication and real-time accelerator control.

Functions

As a C/C++ Software Engineer in the SRC Section, you will join a passionate team, and take a key role in bringing the Accelerator Timing System to a new technological era. For this, you will use White Rabbit, a novel, IEEE standard, Ethernet based network with sub-nanosecond accuracy, pioneered by your new colleagues in the CO group. You will be involved in all aspects of the software life cycle, including user requirements gathering, design, development, testing and production deployment of the new solution, following our agile development process.

In particular, you will:

  • Communicate with the end-users of the Accelerator Timing System to understand their needs and help translate these into appropriate solutions.
  • Engage with the world-class electronics engineers who invented the White Rabbit network and take part in defining the functional behaviour of the White Rabbit hardware modules.
  • Develop low-level software to integrate White Rabbit into the Timing System.
  • Participate in the development of the Accelerator Timing software that uses White Rabbit to coordinate the thousands of accelerator devices.
  • Collaborate and share knowledge and solutions with highly skilled and motivated software engineers inside and outside the CO group.
  • Investigate, diagnose and resolve operational problems in collaboration with the end-users of the Accelerator Timing System.
  • Mentor more junior developers.

Qualifications

Master's degree or equivalent relevant experience in the field of computing, computer science, software engineering or a related field.

Experience:

The experience required for this post is:

  • Proven experience in C/C++ development in a Linux (or Unix-like) environment.
  • Proven experience in developing real-time solutions.
  • Experience applying software quality assurance techniques and practice with corresponding tools.

The following are considered assets but are not mandatory:

  • Experience of White Rabbit.
  • Experience in C programming for embedded hard real-time systems (bare-metal and/or RTOS-based).
  • Experience in Java and/or Python development.
  • Experience in mentoring junior team members.

Technical competencies:

  • Knowledge of programming techniques and languages, including practices for creating reusable software components and libraries.
  • Knowledge and application of software life-cycle tools and procedures including DevOps.
  • Testing, diagnosing and optimization of software.
  • Monitoring and troubleshooting of operational software systems.

Behavioural competencies:

  • Achieving results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.
  • Learning and sharing knowledge: keeping up-to-date with developments in own field of expertise and readily absorbing new information. Sharing knowledge and expertise freely and willingly with others; coaching others to ensure knowledge transfer. Thinking "out of the box" and proposing fresh ideas, insights and methodologies.
  • Working in teams: understanding when teamwork is required to achieve the best results; including others accordingly and sharing information. Working well in groups and readily fitting into a team; participating fully and taking an active role in team activities.
  • Demonstrating flexibility: adapting quickly and resourcefully to shifting priorities and requirements. Instigating and promoting change as an opportunity for organisational development.

About CERN

At an intergovernmental meeting of UNESCO in Paris in December 1951, the first resolution concerning the establishment of a European Council for Nuclear Research (in French Conseil Européen pour la Recherche Nucléaire) was adopted.Two months later, an agreement was signed establishing the provisional Council – the acronym CERN was born.Today, our understanding of matter goes much deeper than the nucleus, and CERN's main area of research is particle physics. Because of this, the laboratory operated by CERN is often referred to as the European Laboratory for Particle Physics.

Physicists and engineers at CERN use the world's largest and most complex scientific instruments to study the basic constituents of matter – fundamental particles. Subatomic particles are made to collide together at close to the speed of light. The process gives us clues about how the particles interact, and provides insights into the fundamental laws of nature. We want to advance the boundaries of human knowledge by delving into the smallest building blocks of our universe.

The instruments used at CERN are purpose-built particle accelerators and detectors. Accelerators boost beams of particles to high energies before the beams are made to collide with each other or with stationary targets. Detectors observe and record the results of these collisions.Founded in 1954, the CERN laboratory sits astride the Franco-Swiss border near Geneva. It was one of Europe's first joint ventures and now has 23 member states.
