T-Rex Solutions is looking for a CNO Software Developer to work on a program supporting the Intelligence Community, focusing on analyzing systems, developing, and defeating security techniques.

Requirements

  • Demonstrated experience programming in Assembly, C, C++, Java, Perl, or Python

  • Candidates must be able to play both sides of the fence, both developing and defeating new and advanced security techniques.
  • All our engineers write code, but many of our engineers spend as much time taking systems apart as building new ones.
  • A typical day can involve studying disassembly or writing Python to audit a piece of C++ code.
  • May be opportunities to lead small teams of developers and/or researchers.
