Structural & Thermal Analysis Engineer, Solid Missile Systems

The future of aerospace and defense starts here. 

Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands. 

Our Solid Missile Systems (SMS) team is growing, and we are seeking a Structural and Thermal Analysis Engineer to support the design, analysis, and validation of advanced solid propulsion systems.

Role Overview

As a Structural and Thermal Analysis Engineer, you will be responsible for performing high-fidelity structural and thermal analyses to ensure the performance and reliability of our SRM products. You will work closely with design, manufacturing, and test teams to support development, qualification, and production programs.

Key Responsibilities

• Conduct finite element analysis (FEA) for structural integrity, thermal performance, and dynamic behavior of solid rocket motor components.
• Perform coupled thermal-stress analyses to assess material response under extreme conditions.
• Support design iterations by providing data-driven recommendations for component geometry, material selection, and thermal protection systems.
• Develop and validate analytical models using industry-standard software (e.g., ANSYS, Abaqus, NASTRAN, Thermal Desktop).
• Evaluate test data and correlate analytical models with physical testing results.
• Work with manufacturing teams to ensure design feasibility and support process optimization.
• Prepare technical reports, presentations, and documentation for internal and external stakeholders.
• Participate in design reviews, failure investigations, and continuous improvement initiatives.

Required Qualifications

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field.
• 3+ years of experience in structural and thermal analysis of aerospace components.
• Proficiency in finite element analysis (FEA) and thermal modeling tools.
• Understanding of material properties, thermal expansion, and high-temperature structural behavior.
• Ability to interpret engineering drawings, specifications, and test data.
• Strong problem-solving skills and ability to work in a fast-paced development environment.
• This position requires that the employee be eligible and maintain eligibility for a Secret Clearance.

Preferred Qualifications

• Master’s degree in a relevant engineering discipline.
• Experience with solid rocket motors, propulsion systems, or high-temperature materials.
• Knowledge of composite materials, insulation, and ablative thermal protection systems.
• Hands-on experience with testing and data correlation.
