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.Job SummaryThe Mechanical Analysis and Test (MA&T) Department is responsible for ensuring structural and thermal design robustness across the Raytheon portfolio of products.
From preliminary concepts to fielded weapon system support, MA&T delivers innovative structural and thermal engineering solutions utilizing methods ranging from classical fundamental & empirically based techniques to state-of-the-art finite element methods leveraging industry leading commercial tools; all complimented and validated by tests executed in a manner to ensure cost effective yet technically balanced solutions.Raytheon is seeking an experienced Principal Thermal Engineer to join the MA&T Department.
The Thermal Engineer is responsible for detailed thermal analysis on products throughout their lifecycle from initial design trade studies and proposals through qualification testing to enduring production support.
The analyses will cover a wide range of difficult problems, requiring solutions that are imaginative, thorough, practicable, and consistent with organization objectives. The analysis tasks will span the spectrum from classical hand analyses to detailed analyses requiring the use of finite element analysis software.
A Thermal Engineer of this salary grade is expected to have a level of technical competence with thermodynamic principles.
The Thermal Engineer will be held accountable for completing his/her work within the agreed upon cost and schedule.
Additionally, the selected candidate will be expected to present their work for peer reviews and to be a peer reviewer for other engineers’ work.
Finally, the engineer is expected to plan and support tests, perform data reduction and engage in thermal model correlation.What You Will DoPerform Hand Calculations to determine scope of higher detail analysis modelsPerform detailed thermal analyses to solve various program thermal challengesGenerate test plans required to validate analyses and verify hardware compliance to customer requirementsAnalyze test data to validate and correlate modelsWork with experienced analysts on problems of moderate complexity to provide the answers needed under program cost and schedule constraintsReview your work with peers to ensure technical accuracyPresent results to internal, external, and government customersGenerate detailed documentation of work and archive for referenceAct as a technical leader (help define/refine and/or develop MA&T department technical processes and tools) and/or lead analysis/test teamsQualifications You Must HaveBachelor’s degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 8 years of prior relevant experience; An advanced degree in a related field may be substituted for additional years of experience as follows: Master’s is equal to 2 years of experience or a Ph.D. is equal to 5 years of experienceExperience in thermal analysis with any of the following tools: FloTHERM, PATRAN, Thermal Desktop/SINDA or ANSYS or equivalentExperience in mechanical principles to solve classical thermal analysis solutions both inside and outside of finite element tools and an ability to work independently and manage multiple prioritiesDemonstrated experience in thermal testing: Planning, organization, execution, data reduction and correlationDemonstrated experience in leading a team of thermal analysts on major program effortsAbility to obtain a U.S. government issued security clearance.
