York Zhang is a Operations (Supply Chain) at Radiant Industries | Propulsion at NASA, Blue Origin, & Firefly at Radiant. They is proficient in Mandarin Chinese and Hakka Chinese. Colleagues describe them as "I worked with York for six months while he was a Test Engineer at Firefly Aerospace's Briggs test site. In his time there, I have seen him perform the role of a Propulsion Test Engineer, running tests to determine the performance of Firefly's rocket engine thrust chamber and the functionality of Firefly's propellant main valve, and also the role of a Ground Support Equipment Engineer, designing fixtures to test said articles and working towards building a new test stand at Briggs.
Working as part of a small group of engineers, York was able to learn several skills from performing tasks that would ordinarily be distributed among several people. These tasks included everything from being at the controls monitoring various parameters on the test stand and test article during hotfire tests of rocket engine thrust chambers, performing rebuilds and repairs on test stand components like valves and instrumentation whenever required, and interfacing with vendors and suppliers to purchase items required to support test site operations. York was extremely efficient at whatever tasks he was asked to perform primarily because of his methodical style of working, his meticulous note-keeping, and his dedication to working long hours. As a result, we were able to perform several successful tests on propulsion hardware while also steadily adding to our test facilities simultaneously.
In summary, I found working with York to be an extremely pleasant and hassle-free experience and would definitely jump at an opportunity to work with him again.

Stage I Engine Responsible Engineer
Firefly Aerospace" and "York and I have worked together on several occasions; as a design engineer he proved himself competent with 3D modeling tools and general design concepts when modeling fluid system geometry, as a test engineer he was instrumental in creating test support hardware, designing test sequences, running tests, and recording data for propellant valves, and as a responsible engineer he used his skills in researching, planning, and task management to push forward progress on turbo-machinery.
York brings an outstanding work ethic to everything he works on, going above and beyond to dive into details in order to fully comprehend new subjects. He has a unique ability to communicate problems in a way that makes them easier to address, comprehend, and solve.
York has been professional, creative, and effective in completing several projects that we have worked on together. He is a pleasure to work with and I believe that he would be a valuable addition to any team that he is a part of. "
