Miller Engineering and Research Corporation (MERC Aerospace) offers professional expertise for the NASA Goddard Space Flight Center (GSFC) Systems Engineering Advanced Services (SEAS) contract. MERC is a team-oriented aerospace engineering firm dedicated to servicing the aerospace and aeronautical industries with unparalleled customer focus. We believe that great engineering starts with talented people like you. 

Our employees work together as “one team” and are committed to delivering high-quality and creative engineering solutions to our customers in the aerospace and federal government arenas. 


MERC Aerospace is seeking an Electrical Engineer (Test) for the Robot Electronics Unit (REU) in support of the On-Orbit Servicing Assembly and Manufacturing OSAM-1 program NASA’s Exploration and In-Space Services Projects (NExIS) division. This position is located at NASA Goddard Space Flight Center (GSFC) in Greenbelt, MD. 

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 support the OSAM-1 REU team. The OSAM-1 REU subsystem provides the electrical design, integration, test, and delivery of the electronics that drive OSAM-1’s two robotic arms. This candidate will primarily support testing of electronic board-level and box-level assemblies through flight verification, but may also support analysis, design, or assembly as required. 

  • Manage test scripts and related documents using GIT repository concepts. 
  • Develop and run automated test scripts written in a GSFC develop scripting language (STOL) used for testing flight hardware. 
  • Support post test data reduction and analysis.
  • Develop an in-depth understanding of the REU design and requirements.
  • Contribute to the electrical, test, and integration of hardware.
  • Work with testing and validating existing designs, but understand hardware and design processes to execute redesigns if necessary.
  • Follow all project requirements for documentation configuration management and software version control. 
  • Direct troubleshooting efforts to locate faults or design flaws.
  • Manage conceptual design, trade studies, drawing generation, documentation release, and testing requirements.
  • 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 5+ years of related experience; Masters and three (3) years or more experience; PhD and 0 years related experience. 
  • Experience in analysis, design, documentation, assembly, and/or test of PCBs. 
  • Desire to function in a test/assembly/integration capacity, but also ability to execute changes to existing designs. 
  • Design, test, and analysis experience for both analog and digital circuits 
  • Motor controller experience. 
  • Experience with hardware integration and test, system verification and validation, and systems engineering, preferably at NASA or in aerospace. 
  • 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. 
  • Ability to obtain and maintain NASA Electrostatic Discharge (ESD) certification (GSFC-SH-ESDCO300 300-PG-8730.6.1A*). 
  • English proficiency is required to successfully complete the required training and pass testing (written and/or hands-on) to obtain the certification. 


  • OrCAD, AutoCAD, PSpice, Labview, and Visio software experience. 
  • Experience using test equipment such as oscilloscopes, power supplies and Electrical Ground Support Equipment (EGSE) racks. 
  • Experience using data reduction and analysis tools. 
  • Familiar with design of electrical interconnects for spacecraft. 
  • Demonstrated ability to develop requirements, design documents and test plans that comply to higher-level specifications. 
  • Knowledge of Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) considerations with respect to electrical design. 
  • Familiarity with MIL standards and requirements, NASA standards and requirements, AS9100 or ISO 9001. 
  • Thorough understanding of manufacturing-project planning, scheduling, resource management, materials ordering, inventory management, and quality functions.
  • Experience with NASA mission life cycle and review cycle (design reviews, requirements reviews, integration reviews, trade studies, etc.).
