Staff Loads & Dynamics Analysis Engineer

Ursa Major is a company focused on revolutionizing aerospace and defense propulsion systems. As a Staff Loads and Dynamics Analysis Engineer, you will lead load development and vehicle dynamics analysis while mentoring other analysts and collaborating with engineering and manufacturing teams to ensure compliance with structural standards.

Responsibilities:

• You will perform loads development for vehicles and engine programs
• You will lead load spectrum development for service life assessment
• You will perform vehicle dynamics analysis
• You will verify and validate your models
• You will work closely with our test team to request the instrumentation necessary to anchor our analytical models
• You will support GFEM development for vehicles and propulsion systems
• You will propagate loads to vehicle and engine components
• You will collaborate with other engineering teams to develop our systems while ensuring they meet requirements and comply with the structural standards we follow
• You will collaborate with our manufacturing team to assess nonconforming hardware for development and flight components and provide recommended dispositions and repairs
• You will improve our analytical methods and seek out new approaches and tools
• You will provide professional development, mentorship, and technical guidance to peers

Requirements:

• B.S. degree in mechanical, aerospace engineering, or a comparable field
• 8+ years of experience performing L&D analysis
• Comfortable working in a fast-paced, startup environment
• Expertise in dynamic analysis methods (structural dynamics, dynamic loads, acoustics, modal, random vibration, shock response)
• Working experience in loads development for vehicle and/or engine applications
• Experience anchoring analytical models to physical testing
• M.S. degree or higher in Mechanical, Aerospace Engineering, or a comparable field, ideally focusing on solid mechanics, fatigue, fracture, or structural dynamics
• Experience with flutter analysis
• GFEM development and model grounding experience
• Knowledge of turbomachinery-related analytical methods (e.g., generating Campbell diagrams to assess margins on rotordynamics or structural modes or rotating hardware)
• High Cycle Fatigue Analysis (HCF, crack initiation predicted by a stress-life / SN approach)
• Low Cycle Fatigue Analysis (LCF, crack initiation predicted by a strain-life / e-N approach)
• Experience performing Finite Element Analysis (FEA / FEM) using commercial codes (e.g., ANSYS, Abaqus, or NASTRAN-based solvers)
• Experience with Femap/Nastran
• Fracture analysis (crack growth / safe-life and assessing for instability via LEFM, ideally with prior experience using NASGRO)
• Experience with the ANSYS FEA suite
• A strong theoretical background in heat transfer, fluid mechanics, and/or compressible flow
• Prior experience working on safety-critical systems in production environments
• Prior professional experience working on either rocketry or turbomachinery
• Experience supporting failure investigations and root-cause analysis
• A track record of working efficiently in fast-paced engineering environments
• A track record of effective oral and written communications to support your recommendations
• Thermal-Structural static analysis (particularly dealing with nonlinear materials and large strains)
• Fluid analysis (e.g. Computational Fluid Dynamics / CFD or 1-D transient analysis using SINDA/FLUINT or ROCETS)
• Knowledge of composite materials, insulation, and ablative thermal protection systems
