Our Team

Our Purpose

Firefly's purpose is to innovate with relentless courage to unlock space for humanity – in a way only Fireflies can.

"You miss all the shots you don't take. If this is something that interests you, then apply. Being a dedicated, driven team player can carry you far. You can learn about rockets, it's much harder to learn dedication and passion."

– Meagan Roth, Sr. Director of Systems Engineering and Launch

We take care of our employees with some of the best benefits in the industry.

Our team is prepping Eclipse's LOx transfer line for testing! Built using a similar carbon composite architecture as Alpha's LOx tanks, at full thrust the line carries almost 4000 lbm / s of liquid oxygen to Eclipse's 7 Miranda engines. That's like driving a midsize sedan through the transfer line once every second.
