Guidance, Navigation and Controls Systems Ph.D. Engineer

Are you completing your Ph.D. and have a passion for aerodynamics, algorithm design or system analysis?

Do you have a strong desire to work on projects that are critical to the defense of our nation?

If you can answer "yes" to these questions, we want to talk to you!

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 engineering professional with academic experience in navigation, guidance, control or aerodynamic systems to develop systems for air vehicle applications.

The Guidance, Navigation and Control Center (GNC) is responsible for all requirements, trade studies, algorithm designs and performance analyses required to develop RMS products that navigate and guide successfully. The Center's scope includes aerodynamic analysis, wind tunnel testing and model development: flight control system design and analysis; servo and control actuation system design and analysis; strap down and GPS aided navigation system design and analysis; target state estimation, midcourse and terminal guidance design optimization as well as system performance analysis.

Job Description:
The Senior Systems Engineer I is responsible for conducting missile guidance, navigation, air vehicle, control system, embedded software and missile performance analysis and is an entry level position for Ph.D. graduates. Missile guidance tasks include guidance law development, state estimation, sensor fusion, trajectory shaping and miss distance performance optimization. Air vehicle design tasks include aerodynamics/stability & control, kinematic and propulsion system trade studies including computational fluid dynamics analysis, wind tunnel testing and aerodynamic model development. Navigation tasks include system trade studies, component modeling of inertial measurement units (IMU) and global positioning systems (GPS), as well as simulation of navigation algorithms particularly Kalman filters. Control system tasks include autopilot, control actuation system, mechanism and gimbaled seeker servo design. Embedded software includes real-time GNC algorithm development for missile system products. Missile performance analysis includes model development, system optimization and Monte Carlo assessments with expected system disturbances.

Key Responsibilities (Essential Functions):
Development of Missile Guidance Algorithms
Coding of Missile Guidance Algorithms in Higher Order Computer Languages
Development of Aerodynamic Models to include support to Wind Tunnel testing
Development of Simulation Kinematics Models
Analysis of Missile performance both in simulation and flight test

Required Education (including Major):

  • Performance analysis by simulation including verification and validation techniques
  • Optimal guidance theory, trajectory shaping, estimation theory, analysis of random processes, non-linear Kalman filters, particle filters
  • Knowledge of inertial navigation and vehicle state estimation algorithms including Kalman filtering for integration of GPS/GNSS receivers with MEMs inertial measurement units.
  • Research and publications focused on the design and performance analysis of hypersonic vehicles including aerodynamics and propulsion systems of the vehicle
  • Experience (2-4 years) estimating kinematic performance of hypersonic vehicles using tools such as NASA's OTIS tools
  • Experience (2-4 years) in the design of control systems/architectures for hypersonic vehicles
  • Ability to operate independently with minimal supervision
  • Ability to communicate effectively with senior leadership and other engineering disciplines.

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.
