Ursa Major is seeking a Senior Vehicle Structures Engineer to support hypersonic and advanced vehicle programs.

Ursa Major’s teams move fast and does a lot with little. We are looking for a skilled, fast learning individual who will serve as a central member of member of the team and take immediate ownership of their system as a responsible engineer. This role focuses on the structural design, analysis, and integration of vehicle airframe and propulsion-adjacent structures operating in extreme environments. The ideal candidate will be comfortable moving quickly from concept through flight hardware while collaborating closely with customers and internal engineering teams.

Key Responsibilities

• Clean sheet design and analysis of fluid & mechanical vehicle components including tanks, feed systems, propellant management, and fluid systems
• Support rapid development cycles of new designs and changing requirements including testing, data analysis and hands-on hardware work
• Design modifications of existing components and prototypes to increase performance, improve manufacturability or resolve limitations
• Collaborate with the manufacturing, analysis, and test teams to reduce part-to-part variation and discrepancies
• Assemble and test first article prototypes
• Design and develop primary and secondary vehicle structures for hypersonic and advanced flight vehicles
• Perform structural sizing, trade studies, and margin assessments across vehicle and propulsion-integrated structures
• Conduct structural analysis including static, dynamic, vibration, and coupled loads environments
• Support thermal-structural interactions in high-temperature flight regimes
• Collaborate with propulsion, systems, thermal, and mission engineering teams to ensure proper structural integration
• Interface with customers and external partners during design reviews, technical interchange meetings (TIMs), and integrated product team (IPT) meetings
• Develop and manage structural requirements and verification plans
• Support manufacturing through design for manufacturability (DFM) and producibility considerations
• Support test planning and execution, including ground and flight test structural support
• Participate in failure investigations, nonconformance resolution, and continuous design improvement

Required Qualifications

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or related field
• 5+ years of experience in vehicle structures or airframe engineering
• Experience supporting hypersonic, missile, space, or high-performance aerospace vehicles
• Strong fundamentals in:
• Structural mechanics and materials
• Loads and environments
• Structural margins and safety factors
• Demonstrated proficiency with computer aided design and drafting
• Experience with geometric dimensioning and tolerancing per ASME Y14.5
• Experience with finite element analysis (FEA) tools (e.g., NASTRAN, Abaqus, ANSYS)
• Working knowledge of and hands-on experience with fluid, mechanical, and electrical systems
• Strong understanding of industry standards and requirements
• Desire to take ownership and help wherever needed on the team
• Able to delegate tasks and lead large project scope
• Ability to work in a fast-paced environment and stay flexible based on customer demands and company priorities along with daily firefighting
• Ability to work effectively in a fast-paced, hardware-focused environment
• Strong written and verbal communication skills
• Ability to obtain and maintain a U.S. Security Clearance

Preferred Qualifications

• Master’s degree in Aerospace or Mechanical Engineering
• Familiarity with high-temperature materials, composites, and metallic structures
• Experience with hypersonic loads, aero-thermal environments, and TPS integration
• Experience supporting flight test or demonstration vehicles
• Experience with model-based engineering or digital thread tools
• Knowledge of propulsion-adjacent structures (motor cases, mounts, skirts, thrust structures)
• Experience in design and analysis of fluids systems
• Experience operating in ISO 9001 or AS9100 certified organizations
• Experience with SMC-S-016 Test Requirements
• Demonstrated proficiency with fundamental manual or CNC machining equipment and processes (milling, turning)
• Experience with fluids, structural and thermal analysis using Ansys software
• 3+ years of PTC Creo or Siemens NX CAD programs and Windchill PLM software
• Liquid propellant rocket engine design, test, or analysis
