You will drive the evolution of high-precision, Ethernet-enabled data acquisition (EDAQ) systems using modern Cortex-M microcontrollers, ensuring sub-microsecond synchronisation accuracy across distributed infrastructures.

Your role will span from maintaining and advancing our firmware codebase to deploying operational solutions for HL-LHC and testbenches, while pioneering R&D in Gbit Ethernet, wireless technologies, and ultra-precise timing protocols.

Your responsibilities:

• Develop and maintain firmware for high-precision, Ethernet-enabled embedded systems based on Cortex-M microcontrollers.
• Implement and optimise features for real-time data acquisition and sub-microsecond synchronisation across distributed infrastructures.
• Deploy, test, and troubleshoot embedded solutions in operational environments, including testbenches and large-scale systems.
• Collaborate with cross-functional teams to integrate embedded systems with broader data acquisition and control infrastructures.
• Conduct R&D on Gbit Ethernet, wireless communication protocols, and advanced timing synchronisation techniques.
• Participate in code reviews, documentation, and continuous improvement of firmware libraries and tools.
• Support system commissioning, performance analysis, and troubleshooting in collaboration with hardware and software teams.

Your profile:

• Solid understanding of embedded systems and microcontroller architectures, particularly Cortex-M.
• Strong experience with firmware development in C/C++ for embedded platforms.
• Exposure to Ethernet communication protocols and real-time data acquisition concepts.
• Exposure in hardware-software integration, including debugging and testing embedded systems.
• Basic knowledge of version control systems (e.g., Git) and collaborative development workflows.
• Strong problem-solving skills and eagerness to work in a cross-disciplinary team environment.
• Basic knowledge of electronics production and testing.
• Experience working with RTOS would be an advantage.

Skills:

• C/C++ for embedded systems development.
• Knowledge of microcontroller architectures, especially Cortex-M and RISC-V (e.g., MI-V).
• Experience with version control systems (e.g., Git).
• Basic electronics and PCB design skills (e.g., Altium).
• Python for testing, automation, and deployment scripts.
• Spoken and written English, with a commitment to learn French.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in Electronics Engineering (or a related field) and 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.
• You have never had a CERN fellow or graduate contract before.
