About The Position

At RTX, the world's largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world’s most complex problems. With three market-leading businesses, world-class operations, and investments in research and development, RTX offers capabilities and opportunities unmatched by others. Raytheon, a part of RTX, brings over 100 years of experience and engineering expertise to meet today’s mission needs and stay ahead of tomorrow’s threats, delivering solutions that help defend freedoms and deter aggression globally. The Mechanical Analysis and Test (MA&T) Department is responsible for ensuring structural and thermal design robustness across the Raytheon product portfolio, from preliminary concepts to fielded weapon system support. MA&T provides innovative structural and thermal engineering solutions using methods from classical fundamental and empirically based techniques to state-of-the-art finite element methods with industry-leading commercial tools, all validated by cost-effective and technically balanced tests. Raytheon is seeking an early career Thermal Engineer to join the MA&T Department. This Thermal Engineer will be 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 imaginative, thorough, practicable solutions consistent with organizational objectives. Tasks will range from classical hand analyses to detailed analyses using finite element analysis software. The engineer is expected to have technical competence with thermodynamic principles, complete work within agreed-upon cost and schedule, present work for peer reviews, and act as a peer reviewer for others. Additionally, the engineer will plan and support tests, perform data reduction, and engage in thermal model correlation.

Requirements

Bachelor’s degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 2 years of prior relevant experience; Alternatively an advanced degree in a STEM field can be substituted for 2 years experience
