Test Technician (Propulsion & Vacuum Systems) at Kreios Space
Kreios Space is hiring a Test Technician (Propulsion & Vacuum Systems) in Nigrán, Spain. On-site.
About Kreios Space
Kreios Space develops satellites that operate in Very Low Earth Orbit (VLEO), at about 200 kilometers above Earth. The company's propulsion system runs on air and solar power, allowing satellites to remain in VLEO for years. These satellites can take images three times sharper and provide better internet signals directly to unmodified devices. Operating in VLEO reduces radiation exposure and launch costs, and satellites naturally re-enter and burn up at end of life, preventing space debris accumulation.
