Senior RF Systems Engineer (34799)

Ottawa

**Senior RF Systems Engineering Specialist - Satellite Communications** This role requires deep technical expertise in satellite RF communications, with a strong focus on physical layer and Layer 2 system design. A solid working knowledge of Layer 3 and higher protocols is also expected. The successful candidate will bring extensive experience with DVB-S2, DVB-S2X, and DVB-RCS2 standards, along with a strong foundation in RF and digital communications theory. You will have hands-on experience with Adaptive Coding and Modulation (ACM) techniques and a strong understanding of modern antenna technologies, including active and phased array systems. This includes digital beamforming, rapid beam hopping, and antenna performance modelling. The role operates within a systems engineering framework, requiring familiarity with requirements management and the full lifecycle from concept through verification. **Key Responsibilities** * Analyze and review RF link budgets, conduct system-level trade studies, and model signal impairments to evaluate overall communications performance. * Collaborate closely with system architects, RF, antenna, and earth station engineers to allocate functionality between hardware and software while optimizing system performance. * Develop and maintain high-level requirements and specifications for RF links, RF subsystems, and antenna systems, including managing requirement updates as designs evolve. * Define, review, and assess test plans, procedures, and results to verify compliance with system specifications. * Perform system performance characterization and analysis, maintaining detailed performance budgets for assigned system elements. * Provide technical expertise in support of regulatory, spectrum coordination, and market access activities. * Mentor junior engineers and serve as a technical resource for team members with developing domain expertise. * Prepare and deliver technical presentations to internal and external engineering audiences as required. **Education and Experience** * Master's degree or higher in Electrical Engineering or a closely related field, with a focus on RF, antenna and microwave engineering, digital communications, or digital signal processing. * Minimum of 10 years of relevant experience performing system-level RF or satellite communications engineering. * Proven experience with digital communication systems, including spread-spectrum and single- and multi-carrier architectures. * Strong background in modulation schemes such as PSK, APSK, and QAM. * Direct experience with DVB-S2X, DVB-RCS2, and Adaptive Coding and Modulation techniques. * Demonstrated capability in modelling RF communication systems using advanced tools such as MATLAB, Python, or equivalent environments. **Skills and Competencies** * Strong collaborator who performs effectively in cross-functional engineering teams. * Excellent written and verbal communication skills. * Ability to clearly explain complex technical concepts to both technical and non-technical audiences. * High standards for technical quality, accuracy, and documentation. * Capable of managing multiple complex technical challenges concurrently. If you want, I can also: * Make it **more concise** * Adjust the tone (more corporate, more technical, or more startup-style) * Reformat it for **LinkedIn** , an **RFP** , or a **careers page** Salary Range - $110,000 - $140,000
