Backed by a legacy of engineering excellence, reliability and industry-leading customer service, Telesat has grown to be one of the largest and most successful global satellite operators.Telesat Lightspeed, our revolutionary Low Earth Orbit (LEO) satellite network, scheduled to begin service in 2027, will revolutionize global broadband connectivity for enterprise users by delivering a combination of high capacity, security, resiliency and affordability with ultra-low latency and fiber-like speeds. Telesat is headquartered in Ottawa, Canada, and has offices and facilities around the world.The company's state-of-the-art fleet consists of 15 GEO satellites, the Canadian payload on ViaSat-1 and one LEO 3 demonstration satellite. For more information, follow Telesat on X and LinkedIn or visit www.telesat.comOur Lightspeed System Engineering team defines the performance required of all RF elements in the entire satellite communication system. As a Manager Radio System Engineering, you will lead all technical aspects of the radio system architecture of the Telesat Lightspeed systems in terms of air interface definition, concept of operations, functional descriptions and physical implementation of the RF functions. In particular, you will define the functional and performance requirements related to the radio system function as applicable to the satellite payload, user terminals and landing stations.MAIN RESPONSIBILITIES:Bring expert level experience to the existing team in finalizing the definition of all aspects of the radio system implementation involving agile multi-beam phased array antennas using beam hopping.Support the definition concept of operations for all phases of the functional requirements, including user terminal commissioning, network entry, satellite handovers, time synchronization, adaptive coding and modulation (ACM) among others.Serve as principal system architect for the definition of all air interfaces between the user terminals, landing stations and satellite payloads. Review and approve all related requirements in the associated sub systems. Develop strategies for modeling RF link performance accounting for impairments through the difference elements in the system!Work with system architects, RF engineers, antenna engineers, User Terminal and Landing Station engineers, to partition functions between hardware and software domainsWork with system modeling team to provide guidance on system design assumptions to be taken into account in the system model.Work with system operations team to jointly develop mechanisms and constraints for resources assignment, and algorithms such as band width on demand management. Develop strategies for modeling link performance accounting for impairments the difference elements in the system.Work with the network team to ensure a seamless functional interface between the network functions and the radio system.Collaborate with the Verification and Test group to plan proper validation of the requirements to ensure appropriate system performance.Stay involved within DVB standard forum and provide recommendations as part of Telesat's engagement on the forumEDUCATION & EXPERIENCE REQUIRED:B.
