EA​/EP Sr Principal Systems Engineer

About Raytheon (RTX) Systems Engineering and Test Capabilities (SE&TC)

The SE&TC Discipline is the central focus for Mission Systems Integration activities, responsible for defining customer needs, functional and product architecture, requirements definition and decomposition, Model Based Systems Engineering (MBSE), system performance, and System Security Engineering (SSE).

This position can be located in either Tewksbury, MA or Marlborough, MA and may require occasional travel.

The EA/EP and SP Systems Engineer will define radar system architectures, develop concepts of operations, design radar processing algorithms, and develop and decompose system, hardware, and software requirements. The engineer may also perform statistical analysis of radar system performance using real or simulated data in a dynamic development environment to support multiple research and development efforts.
