Ardent Concepts, an Amphenol company, designs and manufactures high-performance multicoax and coaxial interconnect solutions used in next-generation semiconductor, quantum computing, test & measurement, and advanced electronics applications. Our patented technologies deliver high signal integrity in compact, high-performance designs.

Our focus is on helping bring next generation computing to market through novel connector designs for test & measurement, OEM applications, and specialized military applications. Ardent's patented contact technologies are well suited for advanced multi-GHz applications such as board stack connectors, coaxial connectors, FPGA sockets, flex circuit connectors, probe interfaces, and mezzanine card connectors. We have a complete line of high-performance interfaces for the most advanced chipsets such as RF devices, ASICS, switches, processors, and MEMS devices. We support chip to chip, chip to board, board to board, and flex to board applications.

We are currently seeking an experienced Senior RF Development Engineer to join our R&D team in Hampton, NH. This position will provide technical leadership in the development of next-generation RF and passive-component technologies, including in-line attenuators, filters, IR filters, terminations, and related RF components, from initial concept through prototype, validation, qualification, and production.

This role will own projects from concept through prototype, validation, qualification, and production while working closely with internal engineering teams, customers, suppliers, and external technology partners. The ideal candidate is a hands-on RF engineer who is comfortable moving between design, simulation, laboratory testing, troubleshooting, and product development.

This position is located in our Hampton, NH office.
