We have an opening for a senior level software developer to help us construct a simulation and modeling system with 3D animation, being written in C++ on a Silicon Graphics platform. The project involves working with other talented programmers to create an entirely new version of a human factors analysis tool that enables designers to test new ideas through simulating human interaction with complex systems, such as aircraft cockpits (the system, called MIDAS, is described on a NASA Ames home page located on the WWW at: http://ccf.arc.nasa.gov/af/aff/midas). The system is intended to model the perceptual, cognitive, and motor behavior of the human operator, in addition to capturing the vehicle and environment dynamics and geometry. This is an opportunity for someone who enjoys tackling difficult problems in a group setting that still rewards independence and initiative. Requirements include: an undergraduate degree in computer science or a related field and 5 years relevant experience. We are looking for someone who has strong C/C++ programming skills and familiarity with Unix, combined with extensive experience in some of the following areas: - Design and implementation of simulation programs, especially graphical simulations (3D a plus). Knowledge of simulation control approaches and algorithms, modeling and simulation theory, simulation data collection and analysis. Experience with distributed simulations a strong plus. - Architecture development for large and complex software systems. - Object-oriented design (experience with Booch methodology a plus) - Design and implementation of agent-based programs - Design and implementation of distributed systems. Experience with ORBs, IDLs, etc. - Multiprocess or multi-threaded programming, RPC - GUI development, X Window and Motif programming - Domain knowledge in cognitive psychology and/or one or more of the appropriate application areas (e.g., commercial airlines, rotorcraft); Nice but not essential is experience in: - object-oriented databases - using Silicon Graphics computers - 3D graphics - Lisp You should also have the ability to work well with others in producing large software systems. If you are interested, please send your resume to: Sherman W. Tyler, NASA Ames Research Center, MS 262-3, Moffett Field, CA 94035-1000, or email to: styler@mail.arc.nasa.gov (principals only, please).
