Embedded Software Engineer II

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.

You would be responsible for developing embedded flight software and firmware to support a variety of upcoming Orbit Fab missions. You would perform coding, debugging, testing, and troubleshooting of systems and software throughout our development process. Your technical duties involve the design and development of new software products throughout the product lifecycle. A major emphasis will be on reliable software that will perform critical functions for a payload in orbit.

• Develop critical flight software for Orbit Fab's technologies.
• Architect, plan and implement firmware and software solutions for system communication, command, and telemetry to meet mission CONOPS.
• Implement and test software to ensure compliance with systems requirements.
• Assist in overall system design and development, providing input to key decisions and reviews from a flight software perspective.
• Perform documentation of the structure and functionality of flight software.
• Directly interact with the customers, both government and commercial.
• Manage software project/tasks and interactions with contractors and vendors to meet the needs of the project.

• BS degree in engineering from an accredited engineering school + 2 years experience in embedded flight software development OR MS degree in engineering from an accredited engineering school.
