Nice To Haves

• Relevant experience in the design of active components (i.e. Low Noise Amplifiers, Power Amplifiers, etc.), RF systems/modules, is a plus.
• Academical publications in the RF domain are to be considered a competitive advantage.

Responsibilities

• Support RF design and development activities for passive RF, millimeter-wave components, packages and multi-function modules under the guidance of a Senior Engineer.
• Execute EM 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 (VNAs), Power Supplies, Spectrum Analyzers, Oscilloscopes, and others.
• Collect, organize, and analyze measured and simulated data to support design reviews, reports and design-related decisions.
• Prepare the necessary documentation to support Mini-Circuits’ Product Generation Process (PGP).
• 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 the committed timelines and budget.
• Support engineering organization in ISO Audits and Management reviews and participate in internal and external audits.
• Assist senior engineer in drafting company procedures and processes to ensure the highest level of design and manufacturing standards are achieved and maintained.
• Collaborate with peers in the creation of Intellectual Property (IP) to maintain technical relevance in materials and processes, circuital topologies, design methodologies/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.
