Electronics 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 and is dedicated to pushing the frontiers of science and technology, fostering an environment of innovation and collaboration.

Job Overview:
The Electronics Engineer position at CERN involves working on the CASSIA Project, which focuses on developing monolithic active pixel sensors (MAPS) with internal signal gain and low noise. This role is crucial for enhancing the performance of pixel detectors used in high-energy physics experiments, particularly at CERN's High-Luminosity LHC and future FCC experiments. The successful candidate will be responsible for assembling and testing sensor prototypes, improving signal measurements, analyzing data for optimal performance, and collaborating with a multidisciplinary team of engineers and physicists. The position requires a strong background in electronics or physics, with a focus on practical experience in laboratory settings and circuit design.

Duties and Responsibilities:
The duties and responsibilities of the Electronics Engineer include assembling and testing CASSIA sensor prototypes on printed circuit boards (PCBs), supporting and improving signal measurements in laboratory settings, analyzing CASSIA2 for optimal signal collection and time resolution, investigating radiation hardness and gain changes due to irradiation, testing chip amplifier circuits against simulations, and characterizing front-end circuit performance. Additionally, the engineer will improve circuit designs for optimal time resolution, develop integration concepts for pixel designs, and perform circuit design and implementation, including pre- and post-layout simulations for optimized pixel designs and front-end circuits. Collaboration with engineers, physicists, and technicians in a multidisciplinary team is essential.

Required Qualifications:
Candidates must be nationals of a CERN Member or Associate Member State and possess a professional background in Electronics or Physics (or a related field). They should have 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. Additionally, candidates should not have previously held a CERN fellow or graduate contract. The position requires experience with silicon detector modules, laboratory instrumentation, PCB design, electronic measurements, and familiarity with data analysis and circuit simulation.

Educational Background:
The educational background required for this position includes a Master's degree or PhD in Electronics, Physics, or a related field. A strong foundation in electronics and practical experience in laboratory settings is essential for success in this role. Candidates should also have knowledge of monolithic CMOS sensors and experience in circuit simulation and characterization.

Experience:
The position requires candidates to have practical experience with the assembly, testing, and characterization of silicon detector modules or similar systems. Experience with laboratory instrumentation, electronic measurements, and the design of PCBs for ASICs/sensors is crucial. Additionally, candidates should have experience in automating laboratory procedures and data acquisition, as well as familiarity with tools used for the design, integration, and verification of ASICs/CMOS sensors.

Languages:
Fluency in spoken and written English is mandatory, and candidates should demonstrate a commitment to learning French, which is considered a valuable asset for the position.

Additional Notes:
This position is fully onsite and involves working in radiation areas, with potential requirements to work during nights, Sundays, and official holidays as needed by the organization. The contract duration is 24 months, with a possibility of extension up to 36 months. The working hours are set at 40 hours per week. The job reference is EP-ATL-TRK-2026-117-GRAP, and the field of work is Experimental Physics. The position offers a monthly stipend between 6372-7004 Swiss Francs (tax-free), 30 days of paid leave per year, comprehensive health insurance coverage, family allowances, a relocation package, and opportunities for on-the-job and formal training, including language classes.
