Electronics Engineer Silicon Sensors R&D

The position involves developing and testing monolithic active pixel sensors (MAPS) with internal signal gain for high-energy physics experiments at CERN. The role includes assembling and testing sensor prototypes, improving signal measurements, analyzing sensor performance, and collaborating with multidisciplinary teams.

Responsibilities

• Assemble and test CASSIA sensor prototypes on PCBs.
• Support and improve signal measurements in laboratory measurements, irradiations and test beams.
• Analyse CASSIA2 for optimal signal collection and time resolution.
• Investigate radiation hardness and the change of gain as a function of irradiation.
• Test CASSIA2 on chip amplifier circuits against circuit simulation, characterise the front-end (FE) circuit performance for time resolution and signal-to-noise ratio (SNR).
• Improve the design of CASSIA2 circuits for optimal time resolution in LGAD and SPAD mode.
• Develop concepts for integration of CASSIA pixel designs into asynchronous readout pixel circuits in matrices (CASSIA3 studies).
• Circuit design and implementation, design verification, pre-/post-layout simulations for optimised pixel designs and FE-circuits for large matrices.
• Collaborate closely with engineers, physicists, and technicians in a multidisciplinary team.

Requirements

• You are a national of a CERN Member State or Associate Member State, excluding Pakistani and Lithuanian nationals for 2026 start date.
• By the application deadline, you have a master’s degree with 2 to 6 years of professional experience since graduation or a PhD with a maximum of 3 years of professional experience since graduation.
• You are not eligible with only a bachelor’s degree.
• You have never had a CERN fellow or graduate contract before.
• Experience with the assembly, testing, and characterisation of silicon detector modules or similar systems.
• Practical experience with laboratory instrumentation such as probe stations, laser test setups, beam test setups.
• Ability to design PCBs for ASICs/sensors as part of the test system.
• Ability to perform electronic measurements to characterise analogue and digital on-chip circuits.
• Experience in automating laboratory procedures and data acquisition.
• Experience with tools used for the design, integration and verification of ASICs/CMOS sensors.
• Familiarity with data analysis, circuit simulation and electronics debugging.
• Experience working in large, international research collaborations and contributing to common infrastructure or shared facilities.
• Demonstrated ability to plan, prioritise and deliver results under tight schedules.
• Your studies focused on Electronics or Physics.
