Senior Stress Engineer – Advanced Concepts

At BETA Technologies, we apply our intellectual curiosity, passion for aviation, and commitment to sustainability toward a shared mission of revolutionizing electric aviation. Regardless of the position one holds, each team member brings their talent and desire to positively impact the environment and lives of others in a refreshing, vibrant, and inclusive culture. The Senior Stress Engineer will size and substantiate primary and secondary structure for an advanced narrowbody aircraft through conceptual and preliminary design. The role will establish credible structural margins and design guidance across global airframe sizing, wing–pylon and high-lift interfaces, composite and metallic structure, and joints. This position will be based onsite at our South Burlington, VT office location, our Raleigh, NC office. Remote candidates may be considered for a hybrid role, with monthly visits to South Burlington, VT for in person work. How you will contribute to revolutionizing electric aviation: Perform classical and finite element stress analysis of aircraft primary and secondary structures under static, dynamic, ground, pressurization, thermal, and system-interface loads Develop global and local finite element models, free-body diagrams, load paths, internal loads, sizing methods, and margins of safety Support parallel analysis lanes for global sizing and load paths; wing, pylon, and high-lift interfaces; and composites, joints, and local optimization Evaluate strength, stability, stiffness, local failure, joint, bearing, bypass, buckling, crippling, and fastener-load behavior as applicable Provide timely sizing direction to structural designers and close the design-analysis loop as aircraft geometry evolves Define analysis assumptions, methods, allowables, load cases, model-validation needs, and structural test objectives Document analysis and technical risk for design reviews, partner interfaces, and future certification planning Coordinate with Loads, Structural Dynamics, Design, Composites, Materials and Processes, Test, Manufacturing, and suppliers Minimum Qualifications: Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or a related field Five or more years of aircraft structural analysis, sizing, or substantiation experience Strong fundamentals in mechanics of materials, structural stability, finite element analysis, and aircraft load paths Experience with NASTRAN, FEMAP, HyperMesh, Abaqus, or comparable structural-analysis tools Experience analyzing metallic, composite, or hybrid aerospace structures and joints Ability to communicate assumptions, limitations, margins, and design recommendations clearly Must be a US Person to be considered for the role Above and Beyond Qualifications: Transport-category wing, pylon, fuselage, empennage, control-surface, pressure-cabin, or high-lift analysis experience Experience with composite failure criteria, fatigue and damage tolerance,…
