About Yanni Tsetsekos

Hello! I am a recent Mechanical Engineering graduate (B.S. and M.S.) with a passion for aerospace, currently working at Relativity Space (ex SpaceX). During my degree I completed three 6-month long co-ops/internships. For my first co-op, I worked at Lockheed Martin in Moorestown, NJ doing Systems Engineering in Ballistic Missile Defense radar systems, supporting the Long Range Discrimination Radar (LRDR) program. For my second co-op I worked at Piasecki Aircraft Corporation in Essington, PA on hydrogen fuel cell powered VTOL aircraft as a Mechanical Engineer. And at my last co-op I worked at Orbit Fab in Denver, Colorado in Propulsion Engineering for ground fluid test systems. For fun I am a hobbyist amateur astronomer, astrophotographer, and sailor.
