At Raytheon, the foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. Our team solves tough, meaningful problems that create a safer, more secure world.

The Systems Engineering and Test Capabilities (SE&TC) Discipline organization  is the central focus for Mission Systems Integration activities within Raytheon, 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).

We are seeking a talented Electronic Attack / Electronic Protection (EA/EP) Systems Engineer to join a team of engineers that designs and develops world-class Sensor systems in our Tewksbury, MA or Marlborough, MA location. 

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

What You will Do:

The EA/EP and SP Systems Engineer will be responsible for the definition of radar system architectures, the development of concepts of operations for the radar system, the design of radar processing algorithms, and the development and decomposition of system, hardware and software requirements. Opportunities also exist to perform statistical analysis of the radar system performance using real and/or simulated data. Work is performed in a dynamic development environment in support of multiple research and development efforts, working with internal and external customers across related product lines. Focus areas for these radar systems include:

• Algorithm Development

• Signal Processing and Waveform Design

• Electronic Protection Methods

• Phased Array and Digital Beamforming Technology

• Radar Search, Track and Discrimination Design

• Statistical and Numerical Analysis of Radar Performance Data

• Target and Threat Modeling

• Integration and test of large systems

• Model Based System Engineering Development

Qualification You Must Have:

• Typically requires a Bachelor’s in Science, Technology, Engineering, or Mathematics (STEM preferred) and a minimum of 10 years of prior engineering experience or equivalent experience.

• Experience with design, development, and analysis of radar system and software architecture

• Experience in writing and evaluating requirements for digital signal processing functionality

• Strong background in modeling and assessing threat air and ground, RF, Electronic Attack (EA) capabilities, and advanced weapon system concept performance and employment

• Design, implementation and testing of algorithms for detection, discrimination and tracking systems

Qualifications We Prefer:

• Minimum of 3 years of experience with design, development, and analysis of radar system and software architecture

• Ability to perform statistical modeling of radar signals and analyze detection and track performance

• Experience with signal processing techniques in complex propagation environments

• Experience interfacing with customers and lead technical solutions to complex user requirements

• Experience with digital beamforming, adaptive cancellation techniques, clutter filtering and Doppler processing, ambiguity resolution, maximum likelihood estimation, CFAR processing

• Define algorithms to support the optimization of system performance and operations by applying fundamental radar principles and modeling electronic countermeasure (ECM) techniques

• Experience with advanced processing algorithms for clutter and jamming suppression

• Knowledge of RF communications and/or radar systems to generate realistic models and simulations of threat systems and apply these models to quantify the effectiveness o
