Software Engineer

Job description

What you'll do:

As a Software Engineer, you will develop Python applications that support the simulation, automation and operation of radiofrequency systems across CERN's accelerators.

You will contribute to the full software lifecycle, from understanding user needs and designing solutions to testing, deployment and operational support.

You will also collaborate with developers working on C++ real-time control software and contribute to tools and interfaces that connect high-level applications with low-level hardware systems.

Your responsibilities:

- Design, develop, and maintain Python-based software applications and tools for the configuration, monitoring, automation, commissioning, and analysis of RF systems across CERN's accelerator complex.

- Collaborate with engineers and physicists to understand operational requirements and deliver reliable, user-focused software solutions integrated with real-time control systems and C++ middleware components.

- Develop automation, testing, and deployment workflows using modern software engineering practices, including CI/CD, containerised environments, and maintainable software architectures.

- Participate in the deployment, commissioning, operational support, and continuous improvement of software systems used during accelerator operation, including on-call support activities.

- Contribute to technical documentation, knowledge sharing, and software quality practices within the team and the wider controls software community.

Still here?

Let's make a quick check about:

Your profile:

- Solid Python development skills, ideally including scientific libraries (NumPy, SciPy, Matplotlib) and GUI frameworks (PyQt).

- Understanding of C++ sufficient to read and interface with existing control-system code.

- Knowledge of software engineering processes: version control (Git), testing, CI/CD and containerisation.

- Experience delivering production-quality software in scientific or engineering environments.

- Exposure to radiofrequency or accelerator systems is an advantage but not required.

- Master's degree or equivalent relevant experience in the field of computer science, software engineering, applied physics, electronics engineering or a related field.

Your skills:

- Development of application software.

- Development of software for embedded and real-time systems with/without OS.

- Knowledge and application of software life-cycle tools and procedures.

- Testing, diagnosing and optimization of software.

- Has a structured and organised approach towards work; is able to set priorities and plan tasks with results in mind.

-Adapts quickly and resourcefully to shifting priorities and requirements.

- Identifies, defines and assesses problems, takes action to address them.

- Ensures that information, procedures and decisions are appropriately documented.

- Understands when teamwork is required to achieve the best results; includes others accordingly and shares information.

- Spoken and written English, with a commitment to learn French.

Medical hazard:

- Exposure to electromagnetic fields under certain exposure conditions.

Given the occupational health risks associated with this position, the selected candidate must obtain medical clearance before a contract offer is confirmed.

Employment conditions:

- Work in Radiation Areas.

- Interventions in underground installations.

- A valid driving licence.
