    "description": "<p>The CTAO (Cherenkov Telescope Array Observatory) will be the world’s largest and most powerful ground-based observatory for gamma-ray astronomy at very-high energies. The Observatory has recently moved into its most exciting phase of development: the construction phase. Teams around the world are working together to make the CTAO reality. And with sites and staff located in Italy, Germany, Spain and Chile, the CTAO Central Organisation, which manages the construction and operation of the Observatory, is at the very centre of these activities.</p>\n<p><br></p>\n<p>For its Science Data Management Centre in Zeuthen, Germany, the CTAO Central Organisation’s Computing Team is seeking a <span style=\"font-weight: bold\">SUSS Lead Developer</span> to play a key role in the team responsible for the Science User Support System (SUSS) software. This role offers a unique opportunity to contribute to the development of the next-generation gamma-ray observatory at the intersection of astronomy and computing.</p>\n<p><br></p>\n<p>The SUSS software systems and tools cover all aspects of the science operations of the observatory and provide the CTAO science community with the functionalities they need to conduct their research and interact with the observatory. Key components of the SUSS include a web-based platform for submitting and evaluating observation proposals from the science community, software for scheduling observations, and the science archive to store the resulting data products. Dedicated pipelines support their automated analysis and verification. The science community will have access to the data through a web-based science portal and will be provided with research software to analyse them. The SUSS software products comprise a wide range, including a suite of web-based platforms, libraries, pipelines, databases, and data management systems. The SUSS products will be offered as a service or standalone tools to its users. Preparations are underway for the first in a series of planned releases, each designed to deliver enhanced functionality and improved performance.</p>\n<p><br></p>\n<p>You will join the growing SUSS central team and assume a leading technical role within the SUSS work package. This work package is organised with a central team responsible for overall coordination, architecture, integration, and testing, supported by international and distributed contributing teams, each responsible for developing one or more of the SUSS software subsystems. In this role you will steer the development of the SUSS as a whole and guide the software development of the subsystem teams. This role offers the opportunity to work hands-on with SUSS central and subsystem team members, as well as with other product teams and domain experts across the CTAO Computing department.</p>\n<p><br></p>\n<p>Additionally, the CTAO will support your continuous professional development.
