Computing Engineer Applied Physics (EP-DT-SDGRAP)

As an Engineer with a specialisation in software development you will contribute to the maintenance development optimisation and upgrade of software tools used for the coordination of users experiments and activities of the EP irradiation facilities (IRRAD/GIF) at CERN. You will also contribute to explore opportunities to harmonise and consolidate the individual tools aiming to increase synergies exploitation of communalities in the data model(s) and the reuse of programming code and software infrastructure as well as investigate the new opportunities offered by ML/AL in the field of the text data and language (NLP) processing for optimising them.

Your responsibilities

• Adapt and modify the software tools reacting to changes according to the input of the facility coordinators. You will assist with the operation of these tools (IRRAD Data Manager on-line databases RADNEXT TA portal etc.) and enable the seamless flow of information and data between users domain experts and the facility coordinators by providing the technical means and interfaces for doing so.
• Support the maintenance and upgrade of the software tools for the IRRAD and GIF facilities (Beam Instrumentation DAQ & controls gamma-spectrometry laboratory e-logs etc.) and interface with the accelerator teams (BE-OP BE-CSS) for developing operational pages with the WRAP technology as well as back-end servers (FESA etc.).
• Take care of improving the long-term sustainability of the software platform and tools and its integration within the wider IT service structure at CERN (single-sign-on systems database systems file and storage systems backup and recovery etc.).
• Be tasked with fulfilling and organsing all aspects of deployment availability and scalability and will be responsible for the smooth secure and reliable operation and deployments of the IT services relying on the CERN infrastructure and services.

Your profile

• Proven ability to understand and analyse user-requirements and the capability to design plan implement test troubleshoot and deploy modifications to web applications.
• First-hand experience with platform-as-a-service (PaaS) container-based deployment and orchestration strategies.
• Practical experience with test-driven software development (data modelling version control issue and change management documentation etc.).
• Knowledge about web services and APIs and some experience with the use and design of such interfaces.
• Knowledge and experience in modern ML/AI models and tools.
• Experience with aspects of particle physics especially detector R&D and/or irradiation experiments would also be an asset.

Skills

• Knowledge of programming techniques and languages: Python 3.x Django and adjacent technologies (Semantic UI frameworks etc.) is required. Familiarity with PHP Java JavaScript & JQuery Bootstrap would be helpful. Knowledge of C/C/C# would also be an asset.
• Competency in using gitlab for version control is essential.
• Practical experience with at least one of the following relational database systems is expected PostgreSQL MySQL and Oracle (more or all of them would be of advantage); knowledge of APEX database would also be an advantage.
• Some familiarity with Docker and/or OpenShift based container implementations.
• Proficiency in writing low level HTML and XML based user interface template blocks.
• Shell scripting and general Linux based Dev-Ops capabilities
• Some knowledge about hardware for motor controls (ICP-DAS Arduino RS M300 etc.) and/or gamma spectrometry (Canberra DSA-LX etc.) would also be an asset.
• Spoken and written English with a commitment to learn French.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in Software Engineering (or a related field) and have either:
  • a Masters degree with 2 to 6 years of post-graduation professional experience;
  • or a PhD with no more than 3 years of post-graduation professional experience.
• You have never had a CERN fellow or graduate contract before.
