SAIC is seeking a Senior Mechanical Engineer on the OMES II contract in support of the OSAM-1 (On-orbit Servicing, Assembly, and Manufacturing) program in NASA’s Exploration and In-Space Services Projects Division at Goddard Space Flight Center. This position is located in Greenbelt, MD.
The OSAM-1 mission is a Goddard Space Flight Center (GSFC) Exploration and In-Space Services Projects Division (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 engineer will provide mechanical engineering support for the OSAM-1 Tools subsystem. The OSAM-1 Tools subsystem is responsible for the design, fabrication, assembly, and test of the suite of tools required to perform the on-orbit servicing of Landsat 7.
Job duties include:
- Perform design, analysis, and test of complex materials, structural components, functional systems, and tool assemblies for both engineering unit and flight hardware.
- Respin engineering unit tool designs for flight, including selection of appropriate flight materials, design updates, testing, etc.
- Develop original tool designs and elaborate on or update preliminary and legacy design concepts.
- Evaluate completed designs with team members and management and make modifications necessary to achieve the most ideal design.
- Develop and coordinate test programs required to evaluate design work, engineering unit hardware, and flight hardware.
- Support the design and fabrication of the mechanical ground support equipment (MGSE) to safely handle critical and flight hardware.
- Work in lab and cleanroom facilities with hardware, ground support equipment, and test equipment.
- Ensure that the quality, accuracy, and integrity of your technical documentation, reports, and deliverables comply with NASA and OSAM-1 standards, project plans, and policies.
