Institution Overview
EPFL, the Swiss Federal Institute of Technology in Lausanne, is a dynamic university ranked among the top 20 worldwide. With over 6,500 employees, EPFL supports education, research, and innovation within a vibrant campus community of over 17,000 people from 120+ countries.
SCITAS
The SCITAS platform (Scientific IT & Application Support) provides EPFL researchers and partners with access to infrastructure and expertise in High Performance Computing (HPC). SCITAS also contributes to research and development activities so as to maintain the EPFL's reputation as a leading research institution, including SKA scientific activities.
Mission
The Square Kilometer Array (SKA) will be a next-generation radio telescope that will help to answer key questions in astrophysics, drive technological innovation and support human capital development. However, a new growing challenge of radio interferometers is Radio Frequency Interference (RFI). Radio interferometers are often built in remote and radio-quiet locations to avoid terrestrial sources of RFI, however transient radio sources in the sky such as satellites are much more difficult to avoid. These contaminating signals are often discarded with flagging, but it may be possible to subtract these RFI sources instead.
To strengthen our team, we are seeking an HPC application engineer to work on software for RFI mitigation and subtraction.
