About the Job

Requirements

  • A Bachelor of Science in Electrical Engineering (BSEE) and 0–1 year of experience specializing in RF design, including relevant RF coursework, RF/microwave circuit design experience through industry exposure, or RF-related academic capstone projects.
  • A strong academic foundation in RF and microwave engineering principles.
  • Theoretical and basic practical knowledge of designing common RF circuits, including filters, couplers, power dividers, and baluns.
  • Familiarity with electromagnetic simulation tools based on the Method of Moments and Finite Element Method.
  • Demonstrated experience using RF measurement test equipment.
  • Proficiency in scripting and data analysis using coding languages such as Python or MATLAB.
  • Strong accountability and ownership of assigned tasks.
  • Strong relationship management, project management, and problem-solving skills.
  • Proactive approach, including seeking clarification, asking questions, and following up on action items.
  • Curiosity and eagerness to learn, especially in RF design.
  • Focus on learning, execution, and technical skill development rather than independent ownership of designs.
  • Ability to break down technical problems methodically.
  • Organization, attention to detail, and ability to produce clear technical documentation.
  • Ability to work effectively with engineers, technicians, and cross-functional teams.
  • Strong written and verbal communication skills in English.
  • Comfort working in a fast-paced environment with multiple parallel tasks and deadlines.
  • Ability and willingness to comply with corporate safety initiatives and abide by the Company’s Code of Conduct.
  • Ability to meet the physical demands of the job, including regularly talking and hearing; frequently standing, walking, sitting, and using a computer keyboard; occasionally reaching and lifting or moving up to 10 pounds; and close vision and focus adjustment.

Responsibilities

  • Support RF design and development activities for passive RF and millimeter-wave components, packages, and multi-function modules under the guidance of a Senior Engineer.
  • Execute electromagnetic and circuit-level simulations using tools such as Ansys HFSS, Genesys, ADS, or CST.
  • Model designs and run simulation sweeps, parametric studies, and optimizations as directed; analyze and summarize results.
  • Assist with RF measurements and characterization using laboratory equipment such as Vector Network Analyzers, power supplies, spectrum analyzers, and oscilloscopes.
  • Collect, organize, and analyze measured and simulated data to support design reviews, reports, and design-related decisions.
  • Prepare documentation to support Mini-Circuits’ Product Generation Process.
  • Support product characterization, qualification, and test development activities in collaboration with Product, Manufacturing, Quality, and Test Engineers.
  • Work with the Project Management team to plan and execute assigned tasks within committed timelines and budget.
  • Support the engineering organization in ISO audits and management reviews and participate in internal and external audits.
  • Assist a Senior Engineer in drafting company procedures and processes to maintain design and manufacturing standards.
  • Collaborate with peers to create intellectual property relating to materials and processes, circuit topologies, design methodologies and techniques, simulation software and modeling techniques, device characterization techniques, and novel production testing strategies.
  • Create scripts and execute simulation runs to optimize the performance of passive RF, microwave, and millimeter-wave components.

Desired Qualifications

  • Experience designing active components such as low-noise amplifiers and power amplifiers, or RF systems/modules, is a plus.
  • Academic publications in the RF domain are a competitive advantage.
