Senior RF Engineer

About the role

The Electronic Systems business unit is a segment of Molex's Aerospace & Defense Solutions division. With primary locations in California, New Hampshire, Pennsylvania USA and Cumbernauld UK, we design and manufacture high performance mission critical electronics: Rugged power supply and computing systems in VITA VPX and VNX+ form factors RF and Satcom: ADC/DAC digital direct sampling and processing systems FPGA accelerated computing platforms featuring AMD and Altera devices in PCIe form factors Microelectronics: Custom ruggedised and miniaturised assemblies

Responsibilities

• Lead the design and development of advanced RF circuits, subsystems, and modules for applications ranging from wireless communications to radar.
• Perform detailed simulations using ADS, HFSS, and SPICE to optimize performance, minimize losses, and ensure compliance with specifications.
• Translate designs into manufacturable layouts using Altium Designer, collaborating closely with PCB layout engineers to meet RF performance goals.
• Conduct rigorous bench testing, validation, and troubleshooting of prototypes, using state-of-the-art RF test equipment.
• Work cross-functionally with mechanical, digital, and manufacturing teams to ensure seamless integration of RF designs into complete systems.
• Mentor junior engineers, sharing best practices.

Requirements

• 10+ years of hands-on experience in RF design, simulation, and testing.
• Expert-level proficiency with Keysight ADS, Ansys HFSS and SIwave simulation tools.
• Proven track record of delivering high-performance RF designs from concept through production.
• Deep understanding of RF principles, including impedance matching, filter design, and electromagnetic compatibility.
• Strong problem-solving skills and the ability to work independently on complex technical challenges.

Qualifications

• Strong working knowledge of Altium Designer for PCB layout and RF board design.
• Experience of AMD RFSoC or Altera FPGA devices and tools.
• Mil-Spec design practices and compliance (VPX, VNX+ etc).
• Detailed understanding of latest ADC, DAC and clock circuitry from leading suppliers such as TI and ADI.
