Analysis Engineer

ABOUT FIREFLY

Firefly Aerospace is a U.S. based advanced space technology developmental organization focusing on the leading edge of space systems progression. We are committed to providing economical and convenient access to space for small payloads through the design, manufacture, and operation of reliable launch vehicles. If you are great at what you do and would like to work with people who really want to make a difference, then Firefly is the place for you

SUMMARY

Analysis engineers use their world-class analytical skills and expert knowledge in a given area to verify designs and performance specifications. In this process, Analysis Engineers will ensure that Firefly vehicles meet customer requirements and conform to external safety standards. Analysis engineers are involved in the entire engineering process and therefore require excellent communication skills for collaborating with Design Engineers and Systems Engineers.
