The selected candidate will provide engineering support to the ITU and Regulatory division responsible for spectrum engineering and specifically will support the design, coordination and integration of spectrum regulatory components into the design and modeling of the Telesat Lightspeed non-geostationary (NGSO) low-earth orbit (LEO) system, while optimizing performance. This requires close collaboration with the system design team to ensure that all relevant technical aspects of the Telesat Lightspeed system are well understood and reflect the spectrum regulatory constraints and procedures in place. The selected candidate will work with the system design and system modeling teams to efficiently implement and update new/existing algorithms and functionality.
