Job Description
Introduction
Are you a talented software engineer, passionate about full-stack development? Do you have in-depth experience with developing sophisticated web frontends and asynchronous Python backends? Do you feel confident and experienced in working with complex relational databases that must be highly reliable? Are you comfortable in a collaborative development environment using Windows, Linux, Docker, Git, and GitLab CI/CD? Then apply for this unique challenge as the next step in your career. CERN, take part!

You will join the Accelerator Systems Department (SY), which is responsible for the beam-related technical systems of the CERN accelerators. The SY teams design, build and operate equipment systems in all CERN accelerators, and are engaged in ambitious forward-looking R&D programmes.

You will be working within the Electrical Power Converter Group (SY-EPC), responsible for the power converters for the whole CERN accelerator complex, and join the Tools Team within the Converter Controls Software Section (SY-EPC-CCS), which develops and supports the power converters control software and databases for the SY-EPC group.

The section is responsible for a large, distributed control system for more than five thousand power converters and a dozen static VAR compensators. These range in power from a few Watts to 150MW and are used to drive particle beams through the electromagnets in the accelerators, transfer lines and experiments.

Furthermore, the section provides a 24/7 stand-by service to assist technicians with timely resolution of control software issues on site. Consequently, while accelerator systems are in operation, you will be required to be on-call for one week every two to three months (i.e. four to five times a year).

Functions
As a full-stack engineer, you will maintain and develop web tools which empower your control software colleagues as well as power converter experts to operate and maintain power converters, while respecting deadlines and ensuring software quality.

Your activities will include:
Collaborate with cross-functional teams inside SY-EPC to identify requirements for new complex web applications;
Analyse existing, complex workflows and create simplified, well-structured solutions for them;
Design, implement, and document new web applications that meet the identified requirements;
Develop, test, and maintain the full stack of new and existing power converter expert applications including the backend (Python, FastAPI, Oracle, PostgreSQL) and the web frontend (HTML5, CSS3, JavaScript, Vue.js);
Maintain existing Python background services (daemons) and databases;
Regularly conduct and participate in code reviews;
Supervise junior engineers, fostering their professional growth and ensuring high standards of software engineering practices.

Additional Information
Eligibility and closing date:
Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success. We welcome applications from all Member States and Associate Member States.

This vacancy will be filled as soon as possible, and applications should normally reach us no later than September 1, 2024 by 23:59.

Employment Conditions

Contract type: Limited duration contract (5 years). Subject to certain conditions, holders of limited-duration contracts may apply for an indefinite position.

These functions require:
Participation in a regular stand-by duty, including nights, Sundays and official holidays.
Work in Radiation Areas.
Interventions in underground installations.
A valid driving licence.
Job grade: 6-7
