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 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 complemented and validated by tests executed in a manner to ensure cost effective yet technically balanced solutions.

Raytheon is seeking an experienced Senior Principal Structural Engineer, High Temp Materials, to join the Mechanical Analysis and Test Department with a background in high temperature structural materials such as refractory metals, Ceramics, and Ceramic Matrix Composites (CMC’s). In this role, you will be responsible for detailed structural analysis and testing to support all phases of programs including development and production. 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 calculations to detailed analyses requiring the use of finite element analysis software. Testing will range from the coupon and sub-element level for material characterization to subsystem and system level design verification testing. A structural analyst of this salary grade is expected to have a high degree of technical competence and be a recognized technical leader.

The selected candidate will be able to work under general direction and is expected to define the scope and level of analysis/test required to meet objectives. You will act as a technical Subject Matter Expert (SME) to help define and develop the MA&T department technical processes and tools. You will also be held accountable for your individual work within the agreed upon cost and schedule. It is expected that you will present your work for peer reviews and be a peer reviewer for other engineers’ work. The customers of this position will include internal personnel and programs as well as external Government(s) personnel and programs.

This is an onsite position in Tucson, AZ.

What You Will Do:

• Perform detailed structural analysis and testing to support all phases of programs
• Conduct data collection from available sources for material characteristics, and design and recommend tests to address gaps in material understanding
• Generate test plans required to validate analyses and verify hardware compliance to customer requirements
• Analyze test data to validate and correlate models, and/or generate mechanical loads and environments
• Work with limited oversight on complex problems to provide the answers needed under program cost and schedule constraints
• Coordinate and lead technical peer reviews ensuring the technical accuracy of work product as well as acting as a reviewer for others work products
• Present results to internal stakeholders and external customers
• Generate detailed, archival technical reports
