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 Mechanical Analysis and Test  (MA&T)  Department  is responsible for   ensuring structural  and thermal design robustness across the Raytheon portfolio of products .   From  preliminary concept s   to fielded weapon  system  support,  M A&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 a   mid-level career Senior Thermal   Engineer   to join the  MA&T   Department .   The Thermal  Engineer   is responsible for   detailed  t hermal 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,  practical , 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  heat transfer 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.  

This is an onsite position at our Tucson, AZ facility.

What You Will Do    

• Perform Hand Calculations to  determine   scope of higher detail analysis models  

• Perform detailed thermal analyses to solve  various   program thermal challenges  

• Generate test plans  required   to  validate   analyses and verify hardware compliance to customer requirements   

• Analyze test data to  validate   and correlate models  

• Work  with  experienced analysts on problems of moderate complexity   to  provide   the answers needed under program  cost and schedule constraints  

• R eview  your  work  with peers  to ensure technical accuracy  

• Present results to internal, external, and government customers
