This position is located in Greenbelt, MD, but is temporarily remote due to Covid-19.


The OSAM-1 mission is a Goddard Space Flight Center (GSFC) NExIS managed mission. OSAM-1 is a robotic servicing mission designed to refuel a Low Earth Orbit (LEO) satellite. It contains 3 elements: the Flight Element comprised of the OSAM-1 Servicing Vehicle (RSV) and development testbeds, the Ground Element comprised of the systems required to conduct RSV operations and the supporting networks and facilities, and the Launch Element comprised of the Launch Vehicle and supporting facilities and services. The NEXIS is responsible for the design, engineering, development, test and operations of the OSAM-1 Mission through an integrated team at GSFC. The Servicing Payload design, development and RSV integration will be conducted at GSFC.


Job Description

The engineer will serve as the systems engineering expert in the field of Guidance, Navigation, and Control (GN&C) systems on the OSAM-1 Mission Systems Engineering team. This person will be responsible for researching, developing, evaluating, and testing the OSAM-1 GN&C system. They will provide leadership regarding the integration of analytical, hardware, and software disciplines required for GN&C of the OSAM-1 Spacecraft, Servicing Payload and Space Infrastructure Dexterous Robot (SPIDER). They will also serve as the Chair of the Mission GNC Working Group.


Job duties include:

Analyzing mission errors and budgets, including effects of sensor and actuator errors, failure modes, data latency, and structural dynamics.
