Are you passionate about cutting-edge technology and eager to work on innovative projects? We are looking for an Embedded Software Developer to join the Electronics Design and Low-Level Software (EDL) section within the Control Electronics and Mechatronics (CEM) group at CERN, and be part of the White Rabbit Collaboration Bureau. White Rabbit is a CERN-born technology and now an industry-standard that provides sub-nanosecond synchronisation and deterministic data transfer to distributed devices interconnected with a WR network. You will enhance and maintain the basic blocks of this technology, including the software and firmware running on the White Rabbit Switch and the White Rabbit PTP Core, which are deployed in thousands of instances globally. You will also interact with institutes and companies world-wide to help them with integration and deployments of White Rabbit. Your responsibilities: • Develop and maintain software and firmware for the WR Switch and the WR PTP Core. • Maintain GIT repos with dozens of developers. • Develop and maintain tools to automate calibration and tests of WR devices, including hardware in Continuous Integration (CI) pipelines. • Assist in the development of production tests to be conducted post-hardware manufacturing. • Be part of outreach activities in conferences and events to promote WR Technology and the WR Collaboration. • Support WR users world-wide. • Collaborate with your colleagues in the hardware/software co-design process, where HDL, firmware, Linux device drivers and host applications are developed and reviewed together.More information here. Your profile: • Development of embedded Linux software and bare-metal firmware. • Working with an embedded Linux distributions running on SoC of AMD/Xilinx FPGA. • Measurements with lab tools such as an oscilloscope. • Debugging of hardware.Skills: Required: • Low-level programming in C, including bare-metal. • Embedded Linux and Linux Device drivers. • Git-based development, code reviews, merge requests and CI pipelines. • Python. • Spoken and written English, with a commitment to learn French.Advantageous: • Testing frameworks, PyTest. • Basics in FPGA development (VHDL, Verilog, SystemVerilog). • Capability of understanding PCB schematics. • Networking and synchronisation protocols (e.g. NTP, PTP).Eligibility criteria: • You are a national of a CERN Member or Associate Member State. • By the application deadline, you have a maximum of two years of professional experience since graduation in Software Engineering (or a related field) and your highest educational qualification is either a Bachelor's or Master's degree. • You have never had a CERN fellow or graduate contract before. • Applicants without University degree are not eligible. • Applicants with a PhD are not eligible.
