Detector Control System Developer

Job Posting Organization:
CERN, the European Organization for Nuclear Research, was established in 1954 and is one of the world's largest and most respected centers for scientific research. With over 2,500 employees and thousands of scientists from around the globe, CERN operates in multiple countries and is known for its cutting-edge research in particle physics. The organization is dedicated to probing the fundamental structure of the universe using the world's largest and most complex scientific instruments, including the Large Hadron Collider (LHC). CERN's mission emphasizes the importance of diversity and collaboration in achieving scientific breakthroughs.

Job Overview:
The position of Detector Control System Developer is crucial for the ATLAS Experiment at the Large Hadron Collider (LHC), particularly in the development of a new Inner Tracking system (ITk). The successful candidate will be responsible for contributing to the development of the Detector Control System (DCS) based on CERN's SCADA standard WinCC OA. This role requires a motivated individual with a strong background in software, control systems, or instrumentation, who is eager to work on large-scale detector systems in a high-energy physics environment. The developer will collaborate with various teams to ensure the smooth integration of the DCS with the data acquisition system and will be involved in system testing campaigns as needed. This position offers an opportunity to work at the forefront of scientific research and technology, contributing to significant advancements in the field of particle physics.

Duties and Responsibilities:
The key responsibilities of the Detector Control System Developer include:

• Contributing to the development of the future DCS system for the ATLAS ITk detector.
• Maintaining and gradually updating existing DCS instances used in ITk system tests.
• Developing the interface between DCS and the data acquisition system.
• Implementing detailed monitoring of detector components.
• Contributing to the development of DCS online software, including a detector finite state machine.
• Performing architectural design and scaling studies for the final DCS system.
• Fostering collaboration between the current Inner Detector DCS team, ITk sub-project DCS groups, and the central ATLAS DCS team for smooth integration.
• Participating in system testing campaigns when required.

Required Qualifications:
Candidates must possess hands-on experience with detector control systems and profound knowledge in WinCC OA. Additionally, experience in the development and operation of OPC UA servers is essential. Familiarity with common programming languages such as C++ and Python is required, along with experience in operating and testing large-scale detector systems. The ability to work effectively in multi-disciplinary teams and present work to collaborators is crucial. Candidates must also demonstrate a commitment to learning the basics of either English or French, depending on their primary language.

Educational Background:
The ideal candidate should have a professional background in Applied Physics or a related field. Candidates must hold either a Master's 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. It is important that candidates have not previously held a CERN fellow or graduate contract.

Experience:
The position requires candidates to have a professional background in Applied Physics or a related field, with specific experience requirements based on their educational qualifications. Those with a Master's degree should have between 2 to 6 years of relevant professional experience, while candidates with a PhD should have no more than 3 years of post-graduation experience. This ensures that the selected candidate has adequate exposure to the field and is capable of contributing effectively to the team.

Languages:
Proficiency in spoken and written English or French is mandatory, with a commitment to learn the basics of the other language being a requirement. This bilingual capability is essential for effective communication within the diverse international team at CERN.

Additional Notes:
The position is a full-time role with a contract duration of 24 months, which may be extended up to a maximum of 36 months. The working hours are set at 40 hours per week. The target start date for this position is October 1, 202

• The role may involve work in radiation areas, interventions in underground installations, and working during nights, Sundays, and official holidays as required by the needs of the organization. The compensation includes a monthly stipend ranging between 6287 and 6911 Swiss Francs per month (net of tax), coverage by CERN's comprehensive health scheme, and various allowances depending on individual circumstances. Additionally, employees are entitled to 30 days of paid leave per year and will receive on-the-job and formal training at CERN, as well as in-house language courses.
