Job Summary

As a RF Systems Test Engineer at Lynk, you will wear many hats in the world of RF hardware/electronics and software/firmware. The immediate role of the RF Systems Test Engineer will be to support testing of the company’s digital phased array antenna payload hardware in the lab environment. While playing with all this hardware on a bench, you will probably need to pick up a soldering gun, assemble circuits on a breadboard, use an oscilloscope, vector network analyzer, and spectrum analyzer.

This role is critical to the success of our mission, as you will be at the center of developing and executing the automated testing and verification for every aspect of the digital phased array payload that makes our service possible. As an RF Systems Test Engineer you will be expected to understand every detail of this complex system design and its expected function, including high speed mixed signal beamformer boards, clock distribution networks, RFFE boards, integrated radiating antenna elements, and full array calibration and verification procedures.

Core Responsibilities

• Integrate flight and lab RF hardware electronics, design test beds, fixtures, etc. for operational verification of RF hardware and software technologies.
• Design, develop, and document test and integration procedures for flight and lab RF hardware, particularly RF Front Ends, and Mixed-Signal Digital Electronics.
• Design, develop, specify, and maintain hardware and software for Electronic Ground Support Equipment aka EGSE to be used to support satellite RF digital phased array payload verification, particularly before, during, and after functional and environmental testing.
• Bench-level work with electronics to debug and troubleshoot issues that arise during testing, including functional and environmental testing.
• Working alongside engineers and technicians, Inform the design, development, and optimization of the company’s operational testing procedures and policies for our Production and research and development campaign for our space technology.
