Applied Physicist / Systems Engineer

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading scientific research institution established in 195

• It is located in Geneva, Switzerland, and is known for its groundbreaking work in particle physics. CERN employs over 2,500 staff members and collaborates with thousands of scientists from around the world, representing more than 100 nationalities. The organization operates in multiple countries, with its primary focus on advancing our understanding of the universe through high-energy physics experiments, including the Large Hadron Collider (LHC).

Job Overview:
The position of Applied Physicist / Systems Engineer at CERN is pivotal in the ongoing development and enhancement of the LHCb experiment's Timing and Fast Control (TFC) system. This role requires a deep understanding of Data Acquisition and Readout technologies, as well as expertise in timing reception and distribution, networking, and hardware design. The successful candidate will lead the initiative to define and implement the upgraded TFC system, which aims to significantly improve the precision of timing distribution to less than 10 picoseconds. This position not only involves technical specifications and validation of a proto-architecture but also requires collaboration with various teams to ensure the successful integration of new technologies into the existing framework. The candidate will engage in a broader R&D program at CERN, contributing to the future of particle physics experiments.

Duties and Responsibilities:
The key responsibilities for this position include modeling, designing, and defining the specifications for the upgraded LHCb TFC system. The candidate will drive an R&D study to evaluate technological backbones using real hardware, write firmware for the central FPGA logic based on operational scenarios, and implement initial hardware testbenches. This includes testing, commissioning, and optimizing the hardware, as well as supporting sub-detector lab test-benches and maintaining dedicated TFC devices. The role demands a proactive approach to problem-solving and the ability to work collaboratively with various teams to achieve project goals.

Required Qualifications:
Candidates must possess proficiency in Hardware Description Languages such as VHDL and/or Verilog, along with proven design experience across diverse FPGA platforms and toolchains. A solid understanding of detector component analysis and optimization, particularly regarding timing requirements, is essential. Knowledge of detector operation, commissioning, and testing, especially in timing reception and distribution techniques, is also required. Familiarity with embedded DAQ protocols and basic PCB design is advantageous, as is knowledge of formal verification of digital logic and HPC networking for data acquisition. Strong documentation skills and the ability to communicate effectively are critical for this role.

Educational Background:
Applicants should have a professional background in Applied Physics or a related field. A Master's degree accompanied by 2 to 6 years of post-graduation professional experience is required, or alternatively, a PhD with no more than 3 years of post-graduation professional experience. Candidates must also be nationals of a CERN Member or Associate Member State and should not have previously held a CERN fellow or graduate contract.

Experience:
The position requires candidates to have a professional background that includes either a Master's degree with 2 to 6 years of relevant experience or a PhD with up to 3 years of experience in a related field. This experience should ideally encompass work in applied physics, systems engineering, or a closely related discipline, with a focus on large-scale experimental setups and data acquisition systems.

Languages:
Fluency 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 CERN community.

Additional Notes:
The contract duration for this position is 24 months, with the possibility of extension up to a maximum of 36 months. The working hours are set at 40 hours per week, and the target start date for the position is September 1, 202

• The role involves working in radiation areas and conducting interventions in underground installations. The compensation includes a monthly stipend ranging from 6287 to 6911 Swiss Francs (net of tax), comprehensive health coverage for the employee and their family, and various allowances depending on individual circumstances. Additionally, employees are entitled to 30 days of paid leave per year and will have access to on-the-job training and formal training opportunities at CERN.
