Job Title: Power Amplifier (PA) Design Engineer

Location: New Jersey

Employment Type: Full-time, Permanent

Department: RF Engineering / Wireless Hardware

About the Role

We are seeking a highly skilled and innovative PA Design Engineer to join our RF Engineering team. In this role, you will contribute to the development of next-generation RF front-end solutions for wireless communications, focusing on Power Amplifier (PA) design, characterization, and linearization techniques for 5G and mmWave systems.

You will work cross-functionally with systems engineers, software developers, and test teams to deliver world-class RF performance. This is a hands-on engineering position with a strong emphasis on lab work, RF simulation, and DPD (Digital Pre-Distortion) integration.

Key Responsibilities

• Design and simulate RF/microwave PAs using tools such as Keysight ADS, Cadence, and AWR Microwave Office
• Perform mmWave PA design and validation for 5G NR applications
• Conduct load-pull testing, linearity assessments, and thermal characterization
• Work with DPD algorithms and linearization techniques to ensure optimal PA performance
• Use lab measurement equipment (e.g., VNAs, spectrum analyzers, signal generators) to validate RF performance
• Collaborate on the development or integration of DPD solutions using C/C++ or MATLAB
• Interpret and apply 3GPP 5G NR specifications to ensure system-level compliance and performance
• Provide support during prototype development, testing, and optimization phases

Requirements

Must-Have Qualifications:

• Bachelor's or Master’s degree in Electrical Engineering, RF Engineering, or a related field
• Proven experience in PA design for wireless applications, particularly mmWave
• Proficiency with RF simulation tools like Keysight ADS, AWR Microwave Office, and/or Cadence
• Hands-on experience with DPD techniques, load-pull setups, and RF lab measurements
• Working knowledge of 5G NR and RF system-level metrics (EVM, ACLR, etc.)
• Strong understanding of RF non-linearity and PA efficiency optimization
• Familiarity with MATLAB and/or C/C++ for algorithm implementation or integration

Nice to Have:

• Experience with GaN or CMOS PA technologies
• Knowledge of electromagnetic simulation tools (e.g., HFSS, CST)
• Exposure to system architecture or transceiver design
