Ian Slamen

Systems Engineer II for Collins Aerospace, a Raytheon Technologies Company.

I graduated high school in Tennessee and moved to Alabama to attend The University of Alabama in Huntsville (UAH) in 2015. While attending UAH, I was involved in multiple organizations, most notably the UAH Student Government Association and Space Hardware Club (SHC). In SHC, I participated in many projects such as CanSat, high altitude ballooning, and outreach. One of my favorite outreach events was Amateur Radio on the International Space Station (ARISS). In this program, students from around the Tennessee Valley were able to talk to ISS astronaut Tim Kopra, while he was in space! This solidified my passion for STEM outreach and I led the SHC outreach team the following year. My team and I developed curricula for outreach events, and visited six local schools, four visits each, over the course of one year.

During 2018-2019, I worked part-time at a local cyber security company called Mission Multiplier, in which I was a Jr. Cyber Security Engineer focused on developing cyber security policies for government contractors, many of which were based in Huntsville. I graduated in the Fall of 2019 and began work with Collins Aerospace on the UH-60 Black Hawk Platform Team.

Through this work I have gained an understanding of many systems concepts, organizational processes, technical knowledge, and the importance of communication within a team. With the help of the Employee Scholar Program, offered by Raytheon Technologies, I am also currently working towards my Masters of Science in System Engineering at George Washington University located in Washington D.C.
