BETA Technologies is revolutionizing electric aviation and seeks a Senior Stress Engineer to size and substantiate primary and secondary structures for an advanced narrowbody aircraft during conceptual and preliminary design phases.
You will establish credible structural margins and design guidance across global airframe sizing, wing–pylon and high-lift interfaces, composite and metallic structures, and joints. The role involves performing classical and finite element stress analysis of aircraft structures under static, dynamic, ground, pressurization, thermal, and system-interface loads. You will develop global and local finite element models, free-body diagrams, load paths, internal loads, sizing methods, and margins of safety.
Key responsibilities include supporting parallel analysis lanes for global sizing and load paths; wing, pylon, and high-lift interfaces; and composites, joints, and local optimization. You will evaluate strength, stability, stiffness, local failure, joint, bearing, bypass, buckling, crippling, and fastener-load behavior as applicable. You will provide timely sizing direction to structural designers and close the design-analysis loop as aircraft geometry evolves. Additionally, you will define analysis assumptions, methods, allowables, load cases, model-validation needs, and structural test objectives. Documentation of analysis and technical risk for design reviews, partner interfaces, and future certification planning is essential. Coordination with Loads, Structural Dynamics, Design, Composites, Materials and Processes, Test, Manufacturing, and suppliers is required.
The position is based onsite at the South Burlington, VT or Raleigh, NC office locations. Remote candidates may be considered for a hybrid role with monthly visits to South Burlington, VT for in-person work. The role requires extended computer work and regular access to office, laboratory, manufacturing, hangar, and structural-test environments. Occasional travel and use of standard personal protective equipment may be required.
REQUIREMENTS:
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
Desired 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, nonlinear analysis, or structural-test correlation
- Experience developing methods, automation, or certification-oriented substantiation documentation
