Systems Integration Engineer (BE-ICS-TMA-2026-91-GRAE) at CERN

Our team develops, operates, and supports industrial control system solutions used across CERN, including accelerators, technical infrastructure, and experimental facilities. We provide integration services for heterogeneous equipment and promotes standardised approaches to ensure reliability, scalability, and maintainability of control systems. In this role, you will contribute to the delivery, operation, and continuous improvement of control system integration services, with a strong focus on OPC UA-based systems and CAN Open devices. Your responsibilities • Support the integration of industrial devices and subsystems into CERN control systems using OPC-UA standards. • Contribute to the operation and support lifecycle, including incident analysis, feedback loops, and continuous service enhancement. • Supporting integration and diagnostics of fieldbus-based systems, including CAN and CANopen, where applicable. • Work in a highly heterogeneous environment involving both commercial and custom-built systems, where reliability and maintainability are critical. • Contribute to the development, maintenance, and operation of validation and testing tools, primarily based on Python. • Design and execute automated validation workflows and test campaigns to ensure compliance, robustness, and performance of integrated systems. • Analyse system behaviour and troubleshoot integration and production issues across a diverse set of deployed systems. • Support users by providing technical expertise, documentation, and guidance on integration solutions and tools.Your profile • Initial experience or strong academic background in industrial control systems, distributed systems or automation. • Exposure to OPC-UA or similar industrial communication protocols, including basic configuration and testing. • Exposure to version control systems (e.g. Git) and structured development workflows. • Experience working on technical projects (academic or professional) involving system integration or automation. • Experience with OPC-UA is preferred.Skills • Strong software engineering fundamentals (requirements analysis, version control, lifecycle management). • Initial experience with Python development. • Initial experience with modern C++ (minimum C++17). • Familiarity with software testing practices (unit and integration testing). • Familiarity with CI/CD concepts and automated testing environments. • Problem-solving skills in diagnostics, debugging and system analysis. • Knowledge of CAN bus and CANopen protocols is preferred. • Familiarity with industrial communication protocols or field systems is preferred. • Exposure to large-scale or mission-critical systems is preferred. • Ability to learn quickly, follow technical guidelines and collaborate within a team. • Spoken and written English, with a commitment to learn French.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, Automation (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.
