Senior Test Engineering Specialist

Senior Test Engineering SpecialistThe successful candidate will develop recommendations and influence system verification and validation for an advanced low Earth orbit (LEO) satellite communications system. The position requires working on-site in Gatineau, Quebec, a minimum of four (4) days per week.
Main Responsibilities
Develop verification matrices for feeder and user link system requirements, including spectrum usage, carrier sizes, polarization, and power control.
Validate link establishment, maintenance, and degradation scenarios.
Design and execute tests for feeder/user link coverage and elevation limits, spectrum assignment by user terminal (UT) and landing station (LS) location, and link behavior under fading, interference, and outage conditions.
Act as the Link Layer subject matter expert for DVB-S2X, DVB-RCS2, and Ka-band link operation.
Perform hands-on link testing in a LEO satellite laboratory, including channel emulation, link impairments, carrier aggregation, and spectrum flexibility.
Configure and operate satellite link emulators, signal generators, spectrum analyzers, and traffic generators.
Verify that products under test meet technical, functional, performance, and business requirements.
Work with antenna vendors, modem teams, and RF engineers to validate end-to-end link behavior.
Support over-the-air (OTA) testing plans and execution for feeder and user links.
Support System Acceptance Planning activities for Launch and Early Orbit Phase (LEOP) and In-Orbit Testing (IOT).
Collaborate with DevOps, Ground Systems, and Satellite teams to support innovative, coordinated verification activities.
Education And Required Experience
B.Sc. in Electrical, Computer, or Systems Engineering and a minimum of one year of relevant satellite communications experience.
5+ years of work with antenna types such as flat-panel, parabolic, and aero antennas, preferably in Ka-band.
5+ years in satellite RF communication systems, including modulation and coding standards such as DVB-S2(X) and DVB-RCS2.
Strong knowledge of RF principles, design practices, and feeder/user link testing and validation.
Hands-on RF test equipment experience: oscilloscopes, signal generators, spectrum analyzers, and satellite channel emulators.
Strong understanding of Ka-band link budgets, polarization, adaptive coding and modulation (ACM), and interference effects.
Knowledge of air interfaces, modems, modulation and coding, and satellite link performance.
Experience with satellite link budget analysis and link impairments.
Experience with Jira, Jama, or similar test/defect tracking tools.
Effective communication with management, engineering teams, and suppliers;
familiarity with Agile methods and geographically distributed teams.
Preferred Qualifications
Experience with Ka-band antenna vendors, flat-panel and aero antennas, BUC/LNB, and other antenna technologies.
Experience supporting LEOP and IOT planning.
Familiarity with MEF standards.
Proficiency with MATLAB, Python, or similar tools.
Strong collaboration and written and oral communication skills.
