Singapore beBeeEngineer Full time $125,000 - $175,000
High-Performance RF Engineer

We are seeking a highly skilled RF Engineer to lead the development of high-efficiency, high-linearity RF PA modules from concept through to production.

The ideal candidate will have hands-on experience with RF power amplifier development, including load-pull, impedance matching, and performance tuning. Proficiency in RF simulation tools (ADS, AWR) and experience with EM solvers (HFSS or CST) is also required.

Key Responsibilities:
  • Design and Develop PA Circuits

Lead PA module development including topology selection, schematic capture, and PCB layout. Design for efficiency, gain, and linearity across a broad frequency spectrum. Apply advanced impedance matching, stability analysis, and EM simulation techniques.

  • Simulation and Validation

Use simulation tools such as ADS, AWR, and optionally HFSS or CST for circuit and electromagnetic analysis. Perform load-pull measurements, S-parameter analysis, and linearity testing. Validate designs in the lab using VNAs, spectrum analyzers, signal generators, and power meters.

  • Collaborate Across Teams

Work closely with PCB layout engineers to ensure best practices in high-frequency design. Coordinate with system architects and digital/RF engineers to meet product specifications. Support product engineering with documentation, design reviews, and lessons learned.

  • Deliver Key Milestones

Familiarize with existing PA architectures, tools, and lab setup. Begin schematic-level design of new PA circuit. Complete first-pass design, initiate simulations, and guide initial PCB layout. Validate the prototype in lab conditions; perform debugging, tuning, and generate a detailed test and evaluation report.

Required Skills and Qualifications:
  • 5+ years in RF PA circuit design and validation

A degree in Electrical Engineering, RF Engineering, or a related field is required. The ideal candidate will have a strong background in RF engineering principles and practices.

Why Join Us?

Help define the next generation of high-performance wireless systems. Solve advanced RF engineering challenges in a collaborative setting. Work at the intersection of RF design, systems engineering, and product development. Build solutions that matter for defense, robotics, and industrial autonomy.
