Job Description
Introduction
Are you a skilled and passionate Software Engineer Are you ready to join CERNs Controls Software and Services group where together with other software engineers you can make a difference Take an active role in the design and development of the control systems used by the CERN installation operation and maintenance teams to model manage control and analyse the behaviour of the particle accelerators. Join CERNs Controls Configuration Settings and Automation (CSA) team and realise your potential. Take Part!
In our team you will have a key role in developing and maintaining high-level control system software necessary to operate some of the worlds most complex machines including the Large Hadron Collider (LHC). Your primary responsibility will be designing and implementing distributed modular applications in Java that form the backbone of the controls infrastructure used to operate CERNs accelerators with precision and reliability.
You will work closely with other software engineers accelerator operators physicists and equipment specialists to translate operational requirements into robust software solutions. These will cover objectives such as coordinating sequences of beam operations managing real-time data flows enabling high-level automation of accelerator processes monitoring critical technical infrastructure and alerting in case of anomalies. As such the software you develop will have a direct impact on the safe and efficient operation of CERNs scientific installations.
You will join:
- The Beams department responsible for the beam generation acceleration diagnostics controls and performance optimisation for the LHC and its injector accelerators.
- The Controls Software and Services group which provides solutions for the control and monitoring of all of the CERN particle accelerators their transfer lines associated experimental areas and various supporting technical infrastructure services.
- The Configuration Settings and Automation section delivering systems to facilitate configuration management for logical and physical configuration of the control system empower accelerator operations teams with mission-critical settings management systems and enable automated accelerator control.
Functions
In this highly collaborative and interdisciplinary environment you will engage in all stages of the software lifecycle from architecture and design through development testing deployment and long-term support. You will also contribute to evolving CERNs software frameworks and core services ensuring they remain modern maintainable and performant.
In particular you will:
- Drive discussions with end-users to understand their needs and help translate these into appropriate solutions;
- Shape the evolution and participate in the development of our software solutions for high-level controls;
- Contribute to the development of the mission-critical software used to monitor and alert anomalies based on data from hundreds of thousands of accelerator and infrastructure devices;
- Collaborate share knowledge and solutions with other highly skilled software engineers 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;
- Take responsibility for one or more key systems after an initial learning period planning the evolution of the system through appropriate user community engagement and subsequent follow-up;
- On-board and mentor junior developers.
