RF Engineer (Amplifier Design)

Key Responsibilities

• Design, simulate, implement, and test multi-stage low-noise RF amplifiers.
• Select and integrate components including MMICs, LNAs, bias networks, and digital attenuators.
• Operate and analyze results from RF test equipment (signal generators, spectrum analyzers, vector network analyzers, etc.).
• Use RF simulation tools such as Keysight ADS, CST Studio, and Ansys HFSS for modeling and optimization.
• Design and integrate EMI/RF shielding solutions for sensitive circuits.
• Perform schematic capture and PCB layout (Altium Designer preferred).
• Calculate and optimize noise figure (NF), SNR, gain, and linearity.
• Collaborate with cross-functional teams to ensure designs are manufacturable and scalable.
• Provide design improvements and performance enhancements based on testing/feedback.
• Ensure compliance with certification standards and industry regulations.
• Stay current with RF amplifier design advancements to drive innovation.

Required Qualifications

• Hands-on experience with RF amplifier design and development.
• Strong knowledge of low-noise/high-gain amplifier circuits.
• Proficiency in RF test equipment operation and measurement techniques.
• Experience with RF simulation tools (ADS, CST, HFSS, or similar).
• PCB layout and schematic design experience (Altium Designer preferred).
• Strong problem-solving skills with focus on performance optimization.

Preferred Qualifications

• Experience with analog circuit modeling using LTspice, QUCS, QSPICE, Tina TI, or similar.
• Familiarity with high-speed digital signal integrity analysis.
• Prior work in RF shielding, noise reduction, and precision circuit optimization.
