Lead Propulsion Engineer

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 space economy.

The core function of the Lead Propulsion Engineer is to develop a team for propulsion products, subsystems and support the technical architectures and propellant roadmap for both low and high pressure systems.

The Lead Propulsion Engineer is expected to support the product development of a variety of different tasks including requirements development, system layout and design, detailed CAD work, vendor management, part procurement and specification, test definition, test operation and reporting, as well as being an active reviewer for critical milestone reviews and test plans. A successful lead will guide the team to perform the system definition tasks required for propulsion and fluid transfer systems in the concept definition phase of Orbit Fab missions, the design life cycle phases as the vehicle or subsystems are handed off to the test team.

This role will require balancing the technical, schedule and cost trades of the product and work closely with the Product/Program manager on meeting requirements and delivery dates.
