    Department.
    Successful candidates will have a BS, MS, or PhD degree in Computer

    Science,

    Computer Engineering, Electrical Engineering or similar technical

    field with a focus in embedded digital signal processing.
    Professional

    experience beyond 5 years is desired, but may not be

    required in all

    circumstances.
    Successful applicants will support the development of a

    state-of-the-art remote sensing and communication systems for autonomous

    underwater vehicles,

    undersea systems, and other marine applications.

    Candidates must
