Senior RF Engineer

Key Responsibilities

• Contribute proactively to the design and development of RF subsystems for our next generation of satellite communication, navigation, or RF monitoring systems.
• Component selection and circuit level design using PCB software (Altium preferred), along with simulation (CST, ADS preferred) where required; including transceivers for UHF, S-, X-, and Ka-bands.
• Management of RF modules through production & test.
• RF module test and fault-find at bench level, environmental level (EMC and thermal vacuum testing), and spacecraft level.
• Lead RF testing, validation, and space qualification efforts for new and existing systems.
• Develop test plans, and operational procedures.
• Provide technical consultancy support to software engineering, payloads, satellite operations, and manufacturing teams.

Qualifications/Experience

• BSc, MSc, or Ph.D. degree in Telecommunications, Microwave, or RF Electronics Engineering.
• 5+ years of working experience on design, development, and testing of RF systems.
• Hands-on RF simulation, design, and manufacturing experience and fault-finding during test.
• PCB schematic capture and layout for RF circuits.
• Experience with laboratory or field RF testing with relevant technical equipment such as Network Analyzer, Signal Analyzer, and Signal Generator.
• Measuring performance of passive and active circuits to provide data that backs up system requirements, including phase noise, compression points, associated chain losses, and signals analysis.
• Tuning of RF circuits to achieve optimal performance.
• Proficient in simulation tools (ADS, CST, HFSS, MATLAB).
• Proven track record of promoting cooperation and teamwork.
• Demonstration of problem-solving skills and solution-oriented approaches when dealing with challenges.
• Flexibility to shifting priorities and operational requirements.
• Attention to detail, highly organized with clear communication skills.
• Proficiency in scripting languages and testing tools (Python preferred).

Desired Skills

• Strong background in high-frequency RF systems (e.g., Ku-band, Ka-band).
• End-to-end RF system analysis, simulation, and optimization.
• Knowledge of frequency spectrum management.
• Knowledge of state-of-the-art RF analog and high-speed digital signal processing techniques and technologies using Xilinx/AMD MPSoC/RFSoC.
• Passive and active antenna design, and antenna measurement techniques.
• Experience of power supply design and EMI mitigation techniques.
• Experience of digital circuit design including microcontroller, FPGA, and high-speed transceivers.
