C++ Software Developer

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 and experienced Software Developer? Are you passionate about creating low-level, real-time solutions? Are you experienced with C++ and the Linux operating system? Do you want to contribute to the unique challenge of making all CERN particle accelerators function in a uniform and synchronised manner? Join CERN's Controls Software & Services group, to work on real-time software for the largest particle physics laboratory in the world. Take Part!

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 CSS Group, responsible for providing and supporting the controls software and infrastructure used to operate and maintain these particle accelerators 24 hours a day.
The FST Section, a dynamic and quality-oriented agile team, responsible for mission-critical software frameworks for communication and real-time accelerator control.

Functions

As a Software Developer, you will join a passionate team and take an important role in the evolution of the low-level real-time frameworks used to control accelerator hardware. You will also help bring the Accelerator Timing System to a new technological era, utilizing White Rabbit, a novel, IEEE standard, Ethernet based network with sub-nanosecond accuracy, pioneered by your future colleagues. 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 to understand their needs and help translate these into appropriate solutions.
Shape the evolution and participate in the development of our core C++ frameworks used for real-time control and integration with various equipment types and PLCs.
Engage with the world-class hardware engineers who invented the White Rabbit network and develop low-level software to integrate the White Rabbit hardware into the Timing System.
Participate in the development of the Accelerator Timing software to coordinate the thousands of accelerator devices.
Collaborate and share knowledge and solutions with highly skilled software engineers both inside the CSS group and across the Accelerators & Technology sector.
Investigate, diagnose and resolve operational problems in collaboration with end-users ranging from equipment specialists to operations teams.
Mentor junior developers.
