The Senior Test Engineering Specialist will issue recommendations and have influence on the system verification and validation of  the Telesat Lightspeed System.

The successful candidate is required to work on-site a minimum of four (4) days per week at our Bethesda, MD office.

 
Main Responsibilities:

• Develop verification matrices for feeder and user link system requirements, including Spectrum usage, carrier sizes, polarization, power control
• Link establishment, maintenance, and degradation scenarios
• Design and execute tests validating: Feeder/User link coverage and elevation limits, Spectrum assignment by UT/LS location, Link behavior under fading, interference, and outage conditions
• Serve as Link Layer SME for DVB S2X, DVB RCS2, and Ka band link operation
  Perform hands on link testing in the LEO Lab, including Channel emulation, Link impairments, Carrier aggregation and spectrum flexibility
• Configure and operate satellite link emulators, signal generators, spectrum analyzers, and traffic generators
• Ensure product under test meets technical, functional, performance and business requirements
• Work closely with antenna vendors, modem teams, and RF engineers to validate end to end link behavior
• Support OTA test planning and execution for feeder and user links
• Support System Acceptance Planning activities for the LEOP and IOT
• Work with other segments like DevOps, Ground Systems, Satellite and foster a collaborative and innovative environment

• B. Sc. in Electrical, Computer or System Engineering and a minimum of 12 years of relevant experience in satellite communications
