We are Raytheon Missile Systems, a technology and innovation leader specializing in defense, security and civil markets where you’ll be part of a diverse global team working together to solve some of the most demanding challenges on the planet.We are seeking an experienced navigation engineering professional with expertise in GPS receiver design, integration, and performance analysis to develop systems for air vehicle applications.

Job Description:

This is a technical expert position within the Guidance, Navigation and Control (GNC) Center performing Global Positioning System (GPS) receiver design, simulation, and analysis. The Principal Navigation Systems Engineer will apply knowledge of GPS and integrated inertial navigation to develop advanced missile capabilities. The engineer will provide expertise in military GPS receiver processing, GPS characterization, simulation modeling, integration, and test data analysis. The role often requires acting as the lead authority in GPS and navigation systems to collaborate across systems, simulation, software, electronics, and integration test disciplines. This technical leader will represent the organization as an expert within the field of GPS and will engage with engineering and program management to guide the successful completion of major program efforts.

U.S. Citizenship status is required as this position needs an active U.S. Security Clearance as of day one of employment.

Key Responsibilities (Essential Functions):

·Development and evaluation of GPS based navigation architectures and requirements

·Simulation modeling and analysis of GPS receiver processing and performance

·Characterization of GPS receiver performance in relevant environments

·Integration and assessment of GPS receivers in air vehicle applications

·Analysis of GPS navigation performance in laboratory and flight test scenarios

·Communication of status, issues, and results with program management and customers.

Required Education (including Major):

B.S. from an ABET accredited institution in Aerospace Engineering or Electrical Engineering.

Required Skills:

·Six (6) years of professional experience in research, development, and test of GPS receivers (or four years of experience with a MS degree or two years of experience with a Ph.D.)

·Three (3) years of experience developing or modifying software in higher level languages, such as C/C++ or MATLAB/Simulink

·Experience in the development of simulation models of GPS receivers including measurement error sources, error budget allocation, mode logic, and performance prediction

·Experience with algorithm development for satellite acquisition, tracking, and receiver measurement formation

·Experience with design of GPS receiver tracking loops, including characterization of platform dynamics and environmental/interference effects on GPS processing

·Exposure to requirements specification and interface control documents (ICD) for GPS

·Familiarity with anti-jam GPS processing techniques and analysis (such as nulling, STAP, or SFAP)

Other Requirements:

·Must have an existing or the ability to obtain a Department of Defense issued Secret Security clearance.

·Must be willing to relocate to Tucson, AZ (comprehensive relocation package available)

This position requires the eligibility to obtain a security clearance. Non-US citizens may not be eligible to obtain a security clearance. The Defense Industrial Security Clearance Office (DISCO), an agency of the Department of Defense, handles and adjudicates the security clearance process. Security clearance factors include, but are not limited to, allegiance to the US, foreign influence, foreign preference, criminal conduct, security violations and drug involvement. Employment is contingent on other factors, including, but not limited to, background checks and drug screens.

Desired Education, Skills and Experience:

·Masters Degree or Ph.D. in Aerospace Engineering or Electrical Engineering.

·Demonstrated experience in a technical lead role for a GPS product or lead role for a small integrated product team (IPT).

·Experience with military GPS modernization particularly M-code signal processing and capabilities

·Experience with GPS satellite constellation simulator test equipment

·Experience with inertial navigation systems (INS) mechanizations

·Experience with integrated INS/GPS navigation systems involving exposure to Kalman filtering / estimation theory

·Applied experience with software defined Global Navigation Satellite System (GNSS) receivers.

·Experience designing robust navigation systems with integrity monitoring including GPS measurement fault detection, isolation, and exclusion
