  • Overview

    Sierra Lobo, offers customers a full range of professional and technical capabilities, including Test and Evaluation, Systems Engineering, and Advanced Technologies. We also develop products and processes related to Cryogenic Fluid and Thermal Management Systems, Densified Propellant Management Systems, and Prototype Extreme Pressure and Temperature Systems. Our customers include the Department of Defense (DoD), the U.S. Air Force, U.S. Navy, U.S. Army, Missile Defense Agency (MDA), and the National Aeronautics and Space Administration (NASA).

    This position is located on the OMES II contract at NASA Goddard Space Flight Center. This position will support the Restore-L program in teh Satellite Servicing Projects Division (SSPD).



    The Restore-L mission is a Goddard Space Flight Center (GSFC) Satellite Servicing Project Division (SSPD) managed mission. Restore-L is a robotic servicing mission designed to refuel a Low Earth Orbit (LEO) satellite. It contains 3 elements: the Flight Element comprised of the Restore-L 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 SSPD is responsible for the design, engineering, development, test and operations of the Restore-L Mission through an integrated team at GSFC. The Servicing Payload design, development and RSV integration will be conducted at GSFC.

    The engineer will support electrical integration across all testbeds and electrical ground support equipment (EGSE) as a member of the Restore-L I&T team. The Restore-L I&T subsystem performs the integration and test of all Restore-L hardware including the servicing payload and spacecraft bus.

    Job duties include:
    • Contribute to the electrical design, test, and integration of hardware to multiple testbeds
    • Responsible for developing, designing, documenting, releasing, and testing of testbed hardware requirements within the program’s schedule, budget, and technical requirements
    • Work with subsystem leads and responsible engineers to identify hardware requirements on the various subsystems and make recommendations for hardware needs within the subsystems and at the mission system level
    • Manage conceptual design, trade studies, drawing generation, documentation release, and testing requirements.
    • Responsible for hardware through the full product life cycle (design, fabrication, debug, integration, test and maintenance support)
    • Interpret detailed component performance specification and Interface Control Drawings (ICD), including assembly manufacturing drawings, parts lists, cable design, and engineering change support
    • Develop parts lists (connector selection, wire gauge sizing, harness assembly drawings, etc.)
    • Incorporate engineering change notices and feedback into the iterative processes for design changes
    • Coordinate manufacturing of hardware and harnesses with onsite fabrication resources and offsite vendors



    • Bachelor’s degree in electrical engineering, or closely related field with 9+ years of related experience
    • Must be able to pass a Government background investigation
    • Experience with hardware integration and test, system verification and validation, and systems engineering, preferably at NASA or in aerospace
    • Experience in testing and writing automated tests, test development, managing test runs, tracking test results, troubleshooting, and measuring progress
    • Experience troubleshooting complex systems using various types of test equipment
    • Experience in executing tests, including functional testing (front-end, back-end, and performance testing)
    • Experienced at authoring and maintaining project documentation
    • Strong proficiency in resolving technical and schedule issues in order to ensure that deliverables are met on schedule
    • Proficiency in advising management, inside and outside own organization, on system architecture, technical results, or risks

    • OrCAD, AutoCAD, PSpice, Labview, and Visio software experience
