About the Role

RTX, the world’s largest aerospace and defense company, unites 185,000 minds to solve complex global challenges. The Mechanical Analysis and Test (MA&T) Department ensures structural and thermal design robustness across Raytheon’s product portfolio, from concept to fielded systems. As a mid-level Senior Structural Engineer, you will perform detailed structural analysis for development and production programs, tackle difficult problems with innovative solutions, and present findings to internal and external stakeholders.

Responsibilities

• Perform detailed structural analyses to support all program phases, from classical hand calculations to finite element analysis (e.g., PATRAN, NASTRAN, ANSYS, ABAQUS).
• Generate test plans to validate analyses and verify hardware compliance with customer requirements.
• Analyze test data to validate and correlate models, or derive mechanical loads and environments.
• Work with limited oversight on complex problems, ensuring solutions meet program cost and schedule constraints.
• Coordinate and lead technical peer reviews, ensuring accuracy and acting as a reviewer for others’ work.
• Present results to internal stakeholders and external government customers.
• Generate detailed, archival technical reports.
• Travel to test sites to support testing or design discussions as needed.

Requirements

• Degree in Science, Technology, Engineering, or Mathematics (STEM) with a minimum of 5 years of relevant experience, or an advanced degree with 3+ years of experience.
• Experience in structural analysis using tools such as PATRAN, NASTRAN, ANSYS, ABAQUS, or equivalent software.
• U.S. citizenship and an active, transferable U.S. government Secret security clearance (required prior to start).

Preferred Qualifications

• Working knowledge of mechanical principles to solve classical structural engineering problems.
• Ability to work collaboratively in a team-based environment and independently.
• 8+ years of professional experience in structural analysis of complex systems (e.g., weapon systems).
• Experience in structural testing: planning, execution, data reduction, and correlation.
• Experience with dynamic shock and vibration analysis.
• Proficiency with solid modeling CAD tools such as CREO or equivalent.
• Experience with MATLAB.
• Strong interpersonal skills and experience leading teams.
• Experience presenting to external customers.

Benefits

• Medical, dental, and vision insurance.
• Life insurance, short-term and long-term disability coverage.
