Firefly Aerospace is a space and defense technology company that enables our world to launch, land, and operate in space – anywhere, anytime. As the partner of choice for critical space missions, Firefly is the only commercial company to launch a satellite to orbit with 24‑hour notice and the only company to achieve a successful Moon landing. Our launch vehicles, lunar landers, and orbital vehicles provide government and commercial customers with full mission services from low Earth orbit to the Moon and beyond. 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
Join our dynamic team of highly skilled machinist with a combined experience of over 300 years of machining who will mentor you to manufacture cutting edge components with the latest tools available in the industry. Learn to manufacture complex geometry rocket engine components made from high temp alloys and be trained on sophisticated machining process’s as well as cutting edge machinery.
We pride ourselves on cross training all machinist on every piece of machinery we have.
Location for this role is at our Manufacturing site in Briggs, TX, 25 minutes north of Cedar Park. 2nd shift openings available now.
RESPONSIBILITIES
Set up and operate 5‑axis CNC machines (mills/turn‑mill centers) for complex aerospace components
Interpret and work from engineering drawings, GD&T, and CAD models
Machine high‑performance materials such as Inconel, titanium, stainless steel, and aluminum alloys
Select tooling, speeds/feeds, and cutting strategies for precision and efficiency
Perform in‑process inspections using precision measurement tools (micrometers, calipers, indicators, CMM interface familiarity preferred)
Collaborate with Manufacturing Engineers to optimize programs and improve cycle times
Troubleshoot machining issues including tool wear, chatter, thermal distortion, and surface finish defects
Maintain proper documentation and ensure compliance with AS9100 quality standards
Support continuous improvement initiatives in machining processes and workflow
Be available to work 2nd shift, overtime as needed
