Within the System Engineering team, lead the technical coordination needed to adapt Lightspeed’s low Earth orbit constellation and associated ground infrastructure for military Ka-band communications supporting the Enhanced Satellite Communications Project - Polar (ESCP-P) and other defence customers. This is a senior individual-contributor role in which you will lead technical work across all Lightspeed teams without managing staff. You will build on established designs, analyses, and test plans, focusing additional analysis where decisions require it.

ESCP-P is intended to meet Government of Canada requirements by providing the Canadian Armed Forces (CAF) with secure, resilient, high-speed communications for operations at home and abroad, particularly in Arctic and other high-latitude regions. The project supports Canada’s Arctic sovereignty and continental defence, including interoperability with the North Atlantic Treaty Organization (NATO) and North American Aerospace Defense Command (NORAD).
