Orbit Fab's mission is to create the foundational infrastructure that will fuel a bustling in-space economy, capable of sustaining permanent jobs in space.

Today, satellites cannot be refueled, which severely constrains their mobility and inhibits the development of economic activities in space.

Orbit Fab breaks the single-use paradigm, pioneering our Gas Stations in Space™ refueling infrastructure and RAFTI™ technology to deliver propellant in space, enabling lower-cost satellite construction, increased maneuverability, precise control, and extended lifespans. The possibilities are unprecedented, opening the doors to unimagined operational strategies and business models.

Since our establishment in 2018, we have already achieved the successful launch of three tankers to space. With offices in both the US and UK, we are working in close collaboration with partners and customers across the space industry. Orbit Fab is rapidly ramping up capabilities and requires exceptional talent to tackle important challenges. Our roles offer wide ranging opportunities to have a demonstrable impact and enable a bustling in space economy.


As a Systems Engineer on Orbit Fab’s team, you’ll provide experience and insight into practical problem solving for complex space systems. A strong candidate will call upon a breadth of experience developing systems under-budget and on time. Your days will consist of leading and mentoring the technical team, development, testing, and production of Orbit Fab’s technologies to enable an On-Orbit Propellant supply for the 21st century of space innovation. In particular, you will serve as the technical team lead for the thermal analysis and mechanical structures subsystems.

You bring knowledge and passion in Space Systems Engineering (specifically, experience across both Big and Small space missions at a variety of institutions) or other complex systems.
