Principal Mechanical Engineer

Senior Principal Structural EngineerRaytheon is seeking an experienced Senior Principal Structural Engineer 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.What You Will Do:Perform detailed structural analysis and testing to support all phases of programsConduct data collection from available sources for material characteristics, and design and recommend tests to address gaps in material understandingGenerate test plans required to validate analyses and verify hardware compliance to customer requirementsAnalyze test data to validate and correlate models, and/or generate mechanical loads and environmentsWork with limited oversight on complex problems to provide the answers needed under program cost and schedule constraintsCoordinate and lead technical peer reviews ensuring the technical accuracy of work product as well as acting as a reviewer for others work productsPresent results to internal stakeholders and external customersGenerate detailed, archival technical reportsTravel to test sites to support test or design discussion (depending on work assignment)Act as a technical leader (help define and develop MA&T department technical processes and tools) and lead teams to meet program milestonesContribute to technical discussions and demonstrate strong interpersonal skills working in a team environmentQualifications You Must Have:Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 10 years of prior relevant experience or an Advanced Degree in a related field and minimum 7 years experienceExperience in structural analysis (i.e. PATRAN, NASTRAN, ANSYS or equivalent software (Dynamic, Static, Non-linear, Transient, etc.)Experience in CMH-17 guidelinesExperience in high temperature material systems for hypersonic aerospaceQualifications We Prefer:Experience in industry standard structural analysisUnderstanding of mechanical principles to solve classical structural analysis both inside and outside finite element tools.Ability to work in a collaborative, team-based environment and independently.Experience contributing to technical discussions and demonstrate strong interpersonal skills working in a team environment.15+ years of professional experience in the structural analysis of complex systems that require collaboration of multiple engineering disciplines (such as a weapon system).Experience in structural testing: planning, organization, execution, data reduction and correlation.Experience designing/analyzing mechanical joints for composite material in high temperature environments.Experience using Digital Image Correlation (DIC) software and practices.Experience using fracture modeling techniques for composite materials (VCCT, CZM).Experience with test planning to evaluate structures designed for high temperature environments.Experience with environmental barrier coatings applied to CMCs.Experience with dynamic shock and vibration analysis.Experience with solid modeling CAD tool such as CREO or equivalent.Experience with MATLAB.Experience presenting to external customers.Ability to travel to government and other facilities in support of program activities.Advanced degree in aforementioned disciplines. ABET is the preferred, although not required, accreditation standard.High temp materials experience for hypersonics as well as Ceramic Matrix Composites (CMC) experience and knowledge.What We Offer:Our values drive our actions, behaviors, and performance with a vision for a safer, more connected world.
