Full-time
Job Description
In this role, you will join the Accelerators Systems Department (SY) and work within the Radio Frequency (RF) Group, which is responsible for the operation, maintenance, and development of RF power amplifiers and accelerating cavities. As part of an ongoing consolidation of the RF systems of the CERN Proton Synchrotron (PS), the existing vacuum tube-based driver amplifiers are planned to be replaced by new solid‑state RF amplifiers. You will contribute to the development of FPGA firmware for amplifier interlock systems and for rapid fault‑detection and protection systems used across the RF systems of the PS Complex. The role also includes supporting the integration and testing of new systems and developing Python tools for automated measurements and hardware validation. The work will involve both laboratory testing and commissioning activities on RF equipment.
Your responsibilities
Develop FPGA firmware for an interlock and protection system as part of a new solid‑state RF amplifier design.
Support the integration, commissioning, and validation of the new interlock system within the PS RF infrastructure.
Develop Python‑based tools for automated hardware testing, measurements, and data analysis.
Develop FPGA firmware for rapid fault‑detection and protection systems for RF systems across the PS Complex.
Your profile
Required experience:
Initial experience in FPGA design and firmware development, preferably using VHDL.
Familiarity with FPGA development environments and verification/debugging tools.
Basic programming experience in Python or a similar language for test automation and data analysis.
Desired experience:
Experience with PCB design and electronic circuit development.
Skills
FPGA programming.
Knowledge of VHDL.
Knowledge of C/C++.
