Jacobs Space Exploration Group (JSEG) is comprised of 10 companies and is located at Marshall Space Flight Center in Huntsville, AL (ranked #11 in Best Places to Live by U.S. News). JSEG has been a primary contractor for NASA since 1989 and supports marquee NASA programs, including the Space Launch System, International Space Station, space optics fabrication, earth and space sciences and advanced propulsion system development. As a partner in NASA’s next generation of space exploration, our jobs are literally history in the making.

Position Description:
Yes, this is rocket science!

This Electrical/Avionics Systems Integration Engineer (Electrical Engineer) position supports the NASA Space Launch System (SLS) Hardware-in-the-Loop (HWIL) labs, and System Emulator equipment from Marshall Space Flight center in Huntsville Alabama. The HWIL labs include the System Integration and Test Facility (SITF), Systems Integration Laboratory (SIL), and multiple Software Development Facilities (SDFs) used to verify the integrated avionics and software systems for the SLS rocket. Collectively these labs are known as the Integrated Avionics Test Facilities (IATF). The System Emulators replicate key system level functions and functional interfaces for NASA manned space flight systems integration activities in various locations across the United States. All of these labs and emulators include numerous real-time software models integrated with Electrical/Avionics systems to achieve detailed simulation of the SLS rocket. 

Work will be performed for the Avionics and Ground Systems Test Branch (ES53) of the SLS program at NASA’s Marshall Space Flight Center in Huntsville, Alabama. This branch is responsible for maintenance, fabrication, integration, operation, assembly, and testing of project hardware and software in support of the noted SLS labs and system emulators.

Primary Responsibilities of this position include:

  • Work in a small team environment to plan and perform Electrical/Avionics system design, integration and test activities for the SIL, SITF, and SDF labs. 
  • Perform data interpretation, assessment, and analysis of integrated electrical/avionics systems.
  • Develop macro & micro electrical/avionics hardware and interconnect solutions to support evolution of SLS HWIL system requirements and capabilities
  • Communicate risks, issues and solutions to peers with various technical backgrounds and areas of expertise
  • Create technical documentation including problem assessment/analysis, test data evaluation, problem resolution reports
  • Present and defend analyses and reports during peer level reviews
  • Communicate (written and verbal) clear and crisp insights and observations of performance of integrated systems
  • Communicate risks, issues and solutions to peers with various technical backgrounds and areas of expertise

These activities will be ongoing as the SLS program completes program phases, reviews and schedule milestones, and as the SLS Launch Vehicle architecture evolves. 

Degree in Electrical Engineering, Computer Engineering or related field is required. Degree from an ABET accredited institution is preferred. Typically, educational requirements are a Masters with at least 3 years of experience or a BS with  at least 5 years of experience. 

  • Minimum of 2 years professional experience in areas with demonstrable relationship to some of the Desired Experience topics.
  • Must have excellent written and oral technical communication skills – must be able to clearly define and describe a technical subject to peers across various engineering disciplines.
  • Demonstrated ability to work with a team of diverse individuals and reach group consensus on technical topics.

Desired experience includes one or more of the following in order of significance: 

  • Previous experience assessing Avionics system behavior and performing test design, test execution, test data collection, and test data analysis for complex aerospace systems (e.g. space launch vehicles, spacecraft, missile systems, aircraft).
  • Read and interpret avionics architecture diagrams, cable interconnect diagrams, and associated system schematics.
  • Electrical/Electronic systems and components operational knowledge – including the design, analysis, and simulation of circuits. Component & circuit knowledge should include foundational R/L/C/Diode/BJT/FET components as well as devices such as op-amps, instrumentation amps, opto-isolators, A/Ds, D/As. 
  • Have, or demonstrate strong willingness to develop, a broad technical capability to integrate real-time HWIL systems. This broad technical capability will range from detailed electronic subsystem and component functional evaluation/analysis/modeling, to large scale complex system level interaction across multiple avionics boxes and electrical/electronic subsystems. 
  • Electrical control and electrical power systems design, integration & test for launch vehicles, aircraft, satellites, or payloads.
  • Integration and/or simulation of sensors such as pressure transducers, RTDs, thermocouples, accelerometers, etc.
  • Integration and/or simulation of solenoid valves, servo valves, or electromechanical actuators.
  • Working knowledge of digital communication technologies such as MIL-STD 1553B, RS422, and RS485 
  • Working knowledge of Data Acquisition Systems, preferably real-time systems

The Jacobs Space Exploration Group (JSEG) offers a partnership in which you can grow personally and professionally within a framework of strong leadership, competitive compensation, and rewarding career paths. Come join our team on the Engineering Services and Science Capability Augmentation (ESSCA) contract whose work is destined to have a long-range effect on future generations!
