.ALBA is the Spanish synchrotron light source, a large research infrastructure operating ten beamlines, complementary facilities, and an Electron Microscopy Center, this last in partnership with other institutions. Currently constructing multiple more beamlines, expanding the Electron Microscopy Center, and integrating advanced data analytics, it sums up a wide range of infrastructures geared toward finding solutions to societal challenges. Located in Cerdanyola del Vallès (Barcelona, Catalonia, Spain), it is funded by the Spanish Government (Ministerio de Ciencia e Innovación) and the Catalan Government (Generalitat de Catalunya, Departament de Recerca i Universitats). The synchrotron light produced by 3 GeV electrons is used by thousands of researchers to analyse and understand the properties and functionality of matter, spanning a wide variety of fields, such as catalytic research, health, energy production/storage, environmental research, communication technologies, or cultural heritage. Our highly motivated staff works in a multidisciplinary work environment with an atmosphere formed by lived diversity, inclusion and respect for our colleagues. One of the goals of our gender equality plan is to reach parity within the Consortium's different divisions and offices, and several actions have been taken to encourage applications from women mostly in scientific, engineer and technical job positions. Located close to Barcelona, in a natural park and well connected by car and public transportation, with excellent connectivity to the world and an employer who understands the importance of life-work balance. Facing an upgrade to ALBA II, a 4th generation facility, which will increase dramatically brightness and coherent flux, ALBA is in a phase of growth and dynamics. Being a part of the ALBA team will promote your career and will give you the opportunities to explore new territories. As a highly motivated and well-trained employee with a strong background in engineering, you will dedicate approximately 50% of your time to shift work, ensuring the safe operation of the accelerator. The remaining time will be spent supporting scientists in various activities. You will thrive and perform a meaningful role in this multidisciplinary, diverse, and international work environment. Your responsibilities will include: During shifts : Conducting survey activities within the Experimental Hall, including visual checks of equipment and addressing any alarms to ensure all equipment is in a safe and secure state. Supporting ongoing experiments in beamlines and laboratories, which involves basic troubleshooting of control software and hardware, scientific equipment, and vacuum systems, as well as assisting in experiment preparation. Ensuring that all safety regulations are strictly followed, monitoring compliance, and reporting any issues. Providing support to the accelerator operator in the control room
