Job Description


SAIC is seeking a Systems Administrator on the OMES II contract in support of the Hybrid Flight Computing Systems (HFCS) project of the On-orbit, Servicing, Assembly and Manufacturing (OSAM-1) program in NASA’s Exploration and In-Space Services (NExIS) projects division at NASA Goddard Space Flight Center (GSFC).  This position is located in Greenbelt, MD.

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. 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.


The HFCS team is a critical payload subsystem responsible for the design, development, integration, and test of the flight software and Field-programmable Gate Array (FPGA) capabilities that execute on the Command and Data Handling (CDH) flight processing system to facilitate autonomous on-orbit capabilities including rendezvous and proximity operations (RPO), robotic servicing, fault management and autonomy, and overall command and telemetry services for payload sensors and avionics.

The HFCS team is developing the in-flight computational hardware, firmware and software to be used on-board the satellite to provide flight and robotic control.  Development currently occurs in a heterogeneous network environment including Linux servers and Windows and Mac user workstations. 

HFCS is looking for a candidate to provide additional system administrator support for the existing infrastructure, working with the existing staff to provide networking, IT security, general IT, and user support.  The successful candidate should have at least 5 years of system administration and IT support experience in a heterogeneous system environment.
