The Institute for Defense Analyses Center for Computing Sciences (IDA/CCS) is looking for outstanding researchers to address difficult computing problems vital to the nation's security. IDA/CCS is an independent, applied research center sponsored by the National Security Agency (NSA). Emphasis areas for IDA/CCS technical staff include high-performance computing, computer vulnerability research, cryptography, signal processing, and advanced techniques for analyzing extremely complex data sets. Stable funding provides for a vibrant research environment, and an atmosphere of intellectual inquiry free of administrative burdens. IDA/CCS and its siblings, the Centers for Communications Research, constitute a non-profit Federally Funded Research and Development Center (FFRDC) that operates in the public interest, free from organizational conflicts of interest, and can therefore assist the Department of Defense in ways that industry and for-profit contractors cannot.
