Northrop Grumman Space Systems is seeking an experienced Spacecraft Subsystem Engineer to support the operation and maintenance of NASA's Chandra spacecraft. The Chandra X-ray Observatory is one of NASA's Great Observatories and delivers ground-breaking science to a world-wide scientific user community.
This individual will work on the Flight Operations Team at the Chandra Operations Control Center (OCC) in Burlington, MA and will interface directly with project scientists from the Smithsonian Astrophysical Observatory, Harvard University, the Massachusetts Institute of Technology, and NASA to help maintain and operate the spacecraft components.
Specific duties include:
Monitoring subsystem state of health through detailed trending and analysis of satellite data
Flight system anomaly resolution, including troubleshooting, execution of response and recovery procedures, and development and test of alternative operating modes
Development of innovative operational approaches and system use techniques
Development or enhancement of spacecraft commanding and telemetry monitoring products and procedures to effectively conduct on-orbit operations
Report generation, briefings, and direct customer interactions
Primary responsibilities will be in the areas of the attitude control and propulsion system elements. The major hardware components include sensors (gyros, fine/coarse Sun sensors, star tracking camera), actuators (reaction wheels, solar array drives, thrusters), and associated data routing/processing electronics, along with the detailed control law software that provides highly accurate pointing and maneuvering performance for the observatory. Working with both software-in-the-loop and hardware-in-the-loop spacecraft simulators at the control center is also a part of this role.
The selected candidate should be a motivated self-starter who is able to work both collaboratively and independently on long and short term investigations/analyses. The Flight Operations Team values the ability to develop and communicate outside-the-box solutions and we share our customer's passion for advancing the understanding of the universe. This position is nominally day shift hours, but the Spacecraft Subsystem Engineer will be expected to be on call for emergencies or critical operational activities, which may require reporting to the Operations Control Center and may occur outside of nominal business hours.

Strong fundamentals in classical and modern control theory/design/analysis
Ability to perform complex system analyses using existing and/or self-developed tools
Ability to work through complex real-time problems quickly and with limited information
BS in STEM discipline with 14 years experience OR Master's degree in STEM discipline, with 12+ years' experience OR PhD with 9 years experience
Expertise in one or more of the following areas: spacecraft guidance navigation and control (including Kalman filters, state determination, attitude estimation), spacecraft and payload/instrument precision pointing system design, analysis and V&V, spacecraft attitude control system analysis, system engineering and design verifications and validation, attitude control sensors/actuators, advanced algorithm development
Strong engineering fundamentals in fluids, thermodynamics, heat transfer, mechanics and materials
Prior experience in liquid rocket propulsion development, design, test and/or flight operations
Experience in on-orbit satellite operations
Experience in the development/enhancement of models for use in planning spacecraft operations
A proven team player and effective leader with excellent communication, interpersonal, verbal and presentation skills.
Proficiency with UNIX/Linux, Matlab, Python, Fortran, Ada, and Excel
Salary Range: $117,700 - $176,500
