The successful candidate will be responsible for the design, analysis, integration, and validation of RF signal chains used in challenging operating environments. This role requires strong expertise in low-frequency RF architectures, receiver and transmitter subsystems, filtering, signal integrity, and system-level performance analysis. The ideal candidate combines deep technical knowledge with a practical, hands-on approach to product development and system validation.\nWhat you'll do\nDesign and develop RF signal chain architectures, including receiver, transmitter, filtering, amplification, and signal conditioning functions for communications systems operating between 3 kHz and 30 MHz.\nAnalyze and optimize system-level RF performance, including sensitivity, dynamic range, selectivity, noise figure, interference mitigation, and signal integrity.\nDevelop subsystem specifications, design requirements, and interface definitions based on system-level performance objectives.\nPerform simulations, calculations, and trade studies to evaluate RF architectures, component selections, and design alternatives.\nSupport hardware integration, laboratory testing, troubleshooting, and performance validation activities throughout the product development lifecycle.\nCollaborate with multidisciplinary teams including hardware, FPGA, software, systems, and test specialists to develop integrated communications solutions.\nInvestigate and resolve complex technical issues related to RF performance, electromagnetic compatibility, and system integration.\nPrepare technical documentation, test plans, design reports, and engineering recommendations while supporting design reviews and customer discussions. \nWhat you'll need to get the job done\nBachelor's degree in Electrical Engineering, Electronics, Physics, or a related technical discipline.\n10+ years of experience developing RF, communications, or signal processing systems.\nVLF High-power Class D/E PA design experience\nStrong expertise in RF system design and analysis within LF, VLF, HF, or similar communications frequency bands.\nExperience with receiver and transmitter architectures, filtering, low-noise amplification, frequency conversion, and signal conditioning techniques.\nProficiency using RF simulation, analysis, and laboratory measurement tools including spectrum analyzers, signal generators, vector network analyzers, and oscilloscopes.\nStrong understanding of electromagnetic theory, noise sources, interference mechanisms, and RF system performance metrics. \nCurrently hold or eligible to obtain Canadian secret clearance (currently hold valid PR status or Citizenship in Canada + 10 years verifiable history). \nWhat will make us REALLY love you\nExperience developing communications systems for maritime, naval, aerospace, defense, or other mission-critical applications.\nFamiliarity with antenna systems, propagation characteristics, and communications techniques in LF, VLF, and HF frequency ranges.\nExperience with digital signal processing, modem technologies, software-defined radio platforms, or FPGA-based communications systems.\nStrong analytical and troubleshooting skills with experience supporting complex system integration and verification activities.","description_format":"text","description_chars":3414,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Electronics
