SUMMARY

Vaya Space aims to make space access affordable, safe, and sustainable. We use modern manufacturing and physics-driven design to innovate solutions for today’s challenges. Our hybrid rocket engines, made from recycled thermoplastics, are set to revolutionize the industry by addressing safety, affordability, and sustainability.
We’re expanding our mission beyond commercial spaceflight to enhance U.S. defense capabilities. As a Propulsion Engineer, you’ll design and develop hybrid propulsion systems for defense missions like tactical missiles, hypersonic air-breathing systems, and missile defense systems.
You’ll join a team of innovative thinkers dedicated to advancing propulsion technology. At Vaya Space, we create high-performing, reliable propulsion systems while reducing costs and development times. You’ll have the opportunity to develop your skills, collaborate with experts, and contribute to impactful projects.
We’re looking for someone who thrives in ambiguity, enjoys collaboration, and is driven to solve complex problems. Strong technical skills, attention to detail, and a proactive attitude are essential.
If you’re ready to shape the future of defense technology and contribute to national security, we encourage you to apply. Let’s make history together.
