Understanding of protocol Layers 3 and above is expected. You will be working with the DVB-S2 protocols; DVB-RCS2, DVB-S2X but a thorough understanding of RF and Communications systems theories is expected. You will have had a thorough exposure to Adaptive Coding and Modulation techniques. Also required is a good understanding of active antenna beam forming technologies including digital beam forming, and fast beam hopping, and general phased array antenna modelling and performance. You will have experience working in a Systems Engineering environment and understand the use of Systems Engineering products to facilitate the orderly progression from requirements through design, implementation and verification. RESPONSIBILITIES:

• Reviewing link budgets, performing system-level interface trade-offs to maximize performance, modelling signal impairments to simulate and model communication systems.
• Working with system architects, RF engineers, antenna engineers, and Earth station engineers, to partition functions between hardware and software domains performing system level interface trade-offs to maximize performance.
• Deriving top-level specifications for RF links and RF and antenna subsystems, and responding to requests to modify the requirements as necessary. Creating and reviewing test procedures and plans, as well as test results, to ensure compliance with the specifications.
• Characterizing and analyzing system performance. Developing and maintaining performance budgets on specific aspects of the system.
• Providing technical support to regulatory, coordination, and market access teams and providing mentorship and technical guidance to junior engineers and those with less domain specific knowledge. You will on occasion be expected to prepare and deliver presentations to the Telesat technical community.

EDUCATION & EXPERIENCE REQUIRED:

• Master's degree or higher in electrical engineering or related discipline with emphasis on some combination of RF/antenna/microwave theory, digital communication theory, or digital signal processing.
• At least 10 years of relevant experience relating to the defined responsibilities.
• Experience working with digital communication systems, spread spectrum, single and multi-carrier techniques, modulation types such as PSK, APSK, QAM.
• Specific experience with modulation standards such as DVB-S2X and DVB-RCS2, as well as with Adaptive Coding and Modulation (ACM) methods.
• Specific experience modelling RF communications systems using higher order tools such as Python, Matlab, etc.

SPECIALIZED KNOWLEDGE, SKILLS AND ABILITIES:

• Work well in a team environment
• Good written and oral communication skills
• Able to present complex ideas to a more general audience
• Committed to excellent work products
• Able to manage several complicated issues simultaneously
