What this actually is

You bring your specialist expertise to AI evaluation. The shape of the work varies but the pattern is the same: review outputs, rate quality, write prompts, flag errors. The platform title (Radio Frequency and Electromagnetic Engineering Expert) reflects the rate band and the expertise required, not the day-to-day work.

How Mercor picks people

  1. Upload your CV and answer the role's written questions.
  2. Do a video interview with Mercor's AI interviewer. Most take about 20 minutes, in English unless the role says otherwise.
  3. Some roles add a skills test. A test you pass once counts for similar roles.
  4. The project team reviews your results and sends offers to the people it picks.

Before you start

  • Take Mercor's free practice interview first. It does not count toward any application.
  • Use Chrome on a computer with a camera and microphone, in a quiet room.
  • You can retake an official interview up to 3 times, but hiring teams see how many times you retook it.

Not every applicant gets an offer. Prepare well for the interview.

About the Role

Mercor is partnering with a leading technology organization to recruit experienced Radio Frequency (RF) and Electromagnetic (EM) Engineering Experts for a short-term project. Experts will apply their hands-on industry experience to analyze and solve complex problems involving RF systems, electromagnetics, antennas, propagation, and related engineering applications.

What You'll Do

  • Solve complex technical problems involving RF and electromagnetic engineering.
  • Analyze RF/EM systems, components, antennas, circuits, and architectures.
  • Apply electromagnetic theory, RF principles, and engineering methodologies to real-world scenarios.
  • Analyze technical specifications, system requirements, simulation results, and engineering data.
  • Evaluate design trade-offs, performance limitations, calculations, assumptions, and proposed solutions.
  • Review and validate technical approaches and results, providing technically rigorous solutions and explanations.
  • Follow project-specific technical guidelines and evaluation criteria.

Who Should Apply

  • Experienced RF, Electromagnetic, Microwave, Antenna, or related engineering professionals with hands-on industry experience.
  • Bachelor's, Master's, or PhD in Electrical Engineering, Electronics Engineering, RF Engineering, Electromagnetics, or a related field.
  • Strong understanding of electromagnetic theory, RF engineering principles, and signal propagation.
  • Practical experience in one or more of:

- RF and microwave systems

- Antenna design and analysis

- Electromagnetic simulation and modeling

- RF circuits and components

- EMC/EMI

- Wireless communications, radar, or sensing

- RF propagation and channel modeling

- RF measurement and testing

  • Experience with tools such as HFSS, CST, COMSOL, MATLAB, ADS, or equivalent is a plus.

Candidates with practical experience applying RF/EM principles to real-world engineering systems are strongly preferred.

Preferred Qualifications

  • Advanced degree in RF Engineering, Electromagnetics, Electrical Engineering, or a related field.
  • Experience with microwave or millimeter-wave systems, antenna arrays, phased arrays, beamforming, or MIMO.
  • Experience in radar, wireless communications, satellite communications, or RF sensing.
  • Experience with electromagnetic simulation, RF characterization, and laboratory testing.
  • Experience translating theoretical RF/EM concepts into practical engineering solutions.
  • Research experience or publications in RF, electromagnetics, antennas, or related fields is a plus.

Project Details

  • Duration: Short-term project
  • Work Type: Technical problem-solving, analysis, and expert evaluation
  • Domain: RF Engineering, Electromagnetics, Antennas, Microwave Engineering, and Wireless Systems

We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.
