Flex Rf Test Engineer information

What are the key skills and qualifications needed to thrive as a Flex RF Test Engineer, and why are they important?

To thrive as a Flex RF Test Engineer, you need a solid background in electrical engineering, RF principles, and hands-on experience with testing and troubleshooting RF circuits. Familiarity with RF test equipment such as spectrum analyzers, network analyzers, and signal generators, as well as proficiency in relevant software tools and industry certifications, is typically required. Strong analytical thinking, attention to detail, and effective communication skills help you identify issues and collaborate with cross-functional teams. These competencies are essential to ensure accurate testing, maintain product quality, and drive the successful development of RF solutions.

How does a Flex RF Test Engineer typically collaborate with cross-functional teams to ensure product quality?

As a Flex RF Test Engineer, you will frequently collaborate with design, manufacturing, and quality assurance teams to develop and execute test plans for new RF products. This involves communicating test results, troubleshooting issues, and suggesting design improvements based on your findings. Regular meetings and documentation are crucial to ensure everyone is aligned on test requirements and outcomes. Effective teamwork helps identify potential problems early, supports continuous improvement, and ensures that products meet both technical specifications and customer expectations.

What is a Flex RF Test Engineer?

A Flex RF Test Engineer is a professional who specializes in testing and validating radio frequency (RF) components, modules, and systems, often for products in the wireless communications sector. They develop and execute test plans, troubleshoot hardware and software issues, and ensure that devices meet required performance standards and regulatory requirements. Flex refers to the company or a flexible work environment, while RF (radio frequency) relates to the technology used in wireless communications. These engineers use specialized equipment to conduct measurements and analyze data, contributing to the development and quality assurance of RF products.

What is the difference between Flex Rf Test Engineer vs Flex Rf Design Engineer?

Job description

We are seeking an experienced RF Designer to lead the design, development, and validation of high-frequency circuits and systems for demanding applications including aerospace, defense, industrial, and medical products. This role requires deep expertise in RF/microwave design, PCB materials, and system integration, along with the ability to work in a customer-facing environment.
Key Responsibilities
  • Design and develop RF and microwave circuits including amplifiers, filters, mixers, oscillators, and antennas
  • Perform schematic capture, simulation, and layout of high-frequency PCBs
  • Select and apply advanced RF materials (e.g., Rogers laminates such as RO4350B, RO4003C, RT/duroid series)
  • Conduct RF simulation using tools such as:
    • Keysight ADS
    • Ansys HFSS
    • Cadence AWR Microwave Office
  • Optimize impedance matching, signal integrity, and EMI/EMC performance
  • Develop RF test plans and perform lab validation using VNAs, spectrum analyzers, and signal generators
  • Collaborate with PCB layout, mechanical, and manufacturing teams to ensure design for manufacturability (DFM/DFA)
  • Interface directly with customers to define requirements, present designs, and support technical reviews

Support prototype builds, troubleshooting, and production ramp-up
Required Qualifications
  • Bachelor's or Master's degree in Electrical Engineering or related field
  • 8+ years of experience in RF/microwave design
  • Strong understanding of transmission lines, impedance matching, S-parameters, and EM theory
  • Hands-on experience with RF test equipment (VNA, spectrum analyzer, power meters)
  • Experience designing multilayer RF PCBs and working with controlled impedance structures
  • Familiarity with high-frequency PCB materials and stack-up design

Preferred Qualifications
  • Experience with mmWave or high-frequency (>10 GHz) designs
  • Knowledge of hermetic and high-reliability packaging techniques
  • Experience with LTCC, hybrid circuits, or module-level RF design
  • Familiarity with military and aerospace standards (MIL-STD, IPC Class 3)
  • Experience designing for harsh environments (temperature, vibration, radiation)

Key Skills
  • RF circuit simulation and modeling
  • Signal integrity and power integrity analysis
  • PCB layout guidance for RF performance
  • Debugging and root cause analysis
  • Strong communication and customer interaction skills

Due to ITAR and / or CUI compliance, this position requires candidates to be a U.S. Citizen.
