TX190: 2501 West University, McKinney 2501 West University , McKinney, TX, 75070 USA

Position Role Type:


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.

Raytheon has an excellent and immediate opportunity available for a Principal FRED Analysis Engineer. The selected candidate will require subject matter expertise level knowledge in FRED Optical Engineering Software.

The position will be based out of our McKinney, Texas location.

The person in this position will contribute to multiple programs in an expert technical advisory role to facilitate problem solving.  This person will assume technical leadership of peer groups and provide technical mentoring to programs as Stray Light Optical specialty subject matter expert to:

  • Translate program requirements into performance-based hardware requirements.

  • Perform analysis and modeling of stray light in optical systems.

  • Provide optical design engineering and manufacturing support for stray light control.

  • Establish stray light requirements and verification plans.

  • Analyze complex Visible and Infrared electro-optical systems for undesirable optical effects due to propagation of light through opto-mechanical system.

  • Generate preliminary baffle designs and select optical component materials.

  • Analyze simple and complex electro-optical systems for stray light paths, scattered energy, pupil control, and radiometric performance.

  • Create accurate opto-mechanical models of light sources, optical surfaces, optical coatings/materials, and structural materials.

  • Generate requirements for particulate and molecular levels, surface roughness/scatter, scratch/dig, material emissivity, baffle edges and location.

  • Perform non-sequential ray tracing, laser beam propagation, polarization, diffraction, coherent and non-coherent.

  • Verify performance utilizing in-house, industry, and government test facilities.

  • Exhibit current expertise with FRED analysis program.

This person will understand customers’ written and un-written requirements for system performance and quality.  This person will be capable of negotiating key performance requirements real-time, while assessing impact on cost, schedule and risk. 

This person will perform validation of requirements verification matrices, and act as program optical expert and present (technical interchange meetings, design reviews, etc.) both internally and before the customer.

This person will support the development and flow down of systems requirements, as well as participate in the requirements, development, implementation and validation of test equipment.  This person will work among engineering disciplines to coordinate use of test equipment during test and the development of procedures for assembly and test of flight hardware.

This person will be performing the lead system engineering analyst role for a highly complex optical system; responsible for analyzing requirements and documenting and, in many cases, negotiating, derived flow-down and interface requirements.  This is a technically highly challenging role. It is made even more challenging as the team balances cost, schedule and quality.  At all times this person will maintain a highly rigorous approach to validation of requirements for the customer. 

The selected candidate will be responsible for the development of advanced Electro-Optical Infrared and Visible Imaging Sensor Systems for use in airborne and space applications. This person will utilize experience in space-based infrared and visible imaging hardware to improve design and development cycle times. 

This person will be responsible for design, integration and testing of advanced optical imaging telescopes and associated hardware, and perform complex critical alignments, testing and troubleshooting of refractive and reflective optical assemblies.  This person will perform radiometric and line-of-sight analyses and budget allocations.   This person will generate radiometric error budgets and calibration procedures and operate within an optical measurement and integration laboratory environment.

Required Skills: 

  • Typically requires a minimum of 8 years of applicable professional experience.

  • Expertise in stray light analysis.

  • Expertise in FRED Optical Engineering Software. 

  • Knowledge of optical testing techniques and model verification.

  • Experience in coherent beam propagation and lasers.

  • Experience with MATLAB or a similar type mathematical modeling program.

  • Experience with airborne and/or space imaging systems.

  • Experience with technical presentations.

  • Ability to develop cost and schedule estimates.

  • U.S. citizenship is required as the position will require you to get a Secret Clearance sponsored by our company within the first year of employment. 

Desired Skills: 

  • Experience with other optical propagation and modeling tools (Code V, Zemax, etc.).

  • Experience with product development.

  • Other optical skills such as alignment and wavefront testing.

  • Understanding of general optical measurement tools.

  • Demonstrated leadership skills.

  • Excellent communication skills.

  • Ability to present data to management and customers.



Typically requires a bachelor’s degree in Science, Technology, Engineering or Mathematics (STEM) discipline.
