ABOUT FIREFLY AEROSPACE
Firefly Aerospace is a space and defense technology company on a mission to reliably and repeatedly launch, land, and operate space systems from Earth to the Moon and beyond. As the partner of choice for critical space missions, Firefly is the first commercial company to launch a satellite to orbit with 24-hour notice and the first company to achieve a successful Moon landing. Headquartered in north Austin, Texas, Firefly is looking for passionate, hardworking innovators to join our team and help fuel our successful trajectory into space.
SUMMARY
This entry level position is for the engineer looking to get in on the ground floor of spacecraft testing. If you're the type who used to take apart the family lawnmower "just to see how it works", then this position is for you. Entry level test engineers can expect to work on Firefly's Component, Structures Test Stands. Test Engineers partner with responsible engineers from across all programs (Alpha, A330/MLV, Blue Ghost and Elytra) and across the company to test and validate hardware in the pursuit of developing, qualifying and accepting flight components. The test team not only supports testing, but also launch operations at Firefly's SLC-2W Launch Site. Engineers learn the ropes and fundamentals of operations at our Briggs test site, then leverage these skills to put Firefly hardware into space. Firefly is a new aerospace company, full of creative and talented people, and the engineers in Launch and Test are the where the “Lox hits the TEA-TEB”.
Engineers on this team are responsible for not just partnering with their fellow engineers to hash out plans to test components to their flight-like limits, but also developing the required infrastructure, mechanical, electrical and software, to support these tests. Engineers are expected to be fast on their feet, adaptive and responsive to challenges. They are expected to be in the field, working in hands on and time sensitive applications. Operations Engineers are expected to be self-sufficient, driven and highly motivated engineers up for learning new skills and taking on challenges to excel.
