Career Opportunity: Engineering/NASA Expendable Launch Vehicle (ELV) Program
Location: Cape Canaveral, Florida
Customer: NASA's Kennedy Space Center
Positions Available:
EMI/RF Position Description
In this position, you will be responsible for analyzing the EMI/RF environments for the NASA-contracted launch vehicles. You will model and assess potential interferences and hazards for items such as electrical fields in the fairing, antenna patterns, and other emitting systems. You will also determine shielding requirements to ensure electromagnetic compatibility within the launch vehicle and spacecraft integrated system. In addition, the EMI/RF Engineer is responsible for performing RF link margin analyses to ensure communications through key events in the launch and ascent sequence. You will need to understand the launch vehicle’s communications capabilities as well as the NASA ground assets. You will also serve as the technical expert for EMI/RF issues and will review and validate launch service providers analyses as well as the test procedures and test setups for launch vehicle testing and integration activities.
The qualified candidate will have at least a Bachelor’s Degree in Electrical Engineering or a related technical field; proficiency in the use of modeling/simulation tools such as Framework, GEMAX, and Matlab®; and expendable launch vehicle experience. In addition, good communication skills and effective technical writing and research abilities are required.
Thermal/Fluid Dynamicist Position Description
In this position, you will be responsible for analyzing thermodynamic environments for NASA-contracted launch vehicles. Specifically, you will develop and analyze a fluid/thermodynamic network model using SINDA/FLUINT to characterize and predict the behavior of the liquid oxygen in the launch vehicle upper stage tank during flight. This fluid/thermodynamic network model will be used in collaboration with thermal analyses to fully understand the physical characteristics of the system as the vehicle flies. The model will include development of stratification and phase change, axisymmetric fluid modeling and slosh modeled wetting. This LO2 tank fluid/thermodynamic network model and interaction with the thermal team will support the NASA IV&V effort. Through this effort, you will document and present results of analyses at periodic engineering reviews.
The qualified candidate will have at least a Bachelor’s Degree (Master’s preferred) in Mechanical/Aerospace Engineering or a related technical field. Also must have expertise in thermodynamics, fluid flow, heat and mass transfer and proficiency in the use of modeling/simulation tools such as SINDA/FLUINT, Thermal Desktop, ANSYS, or TMG. Knowledge of FORTRAN and expendable launch vehicle experience is highly desired. In addition, good communication skills and effective technical writing and research abilities are required. |
