Senior/Principal Airframe Stress Engineer

About the role

As a Senior or Principal Airframe Stress Engineer, you will lead structural analysis efforts supporting the development, certification, and production of Electra's flagship hybrid-electric eSTOL aircraft. This role is responsible for ensuring the structural integrity of metallic and composite airframe components through detailed analysis, testing, and certification substantiation. You will work closely with design engineering, loads, materials & processes, manufacturing, structural test, suppliers, and certification teams to develop robust airframe structures that meet performance, safety, and FAA certification requirements. The ideal candidate combines deep structural analysis expertise with strong engineering judgment and the ability to influence aircraft design decisions throughout the product lifecycle.

Responsibilities

• Support development of major airframe structures from preliminary design through certification, production launch, and manufacturing ramp-up
• Perform static strength, fatigue, and durability analyses for metallic and composite aircraft structures
• Develop structural substantiation methods and analysis plans supporting FAA Part 23 type certification
• Create and validate finite element models using FEMAP/Nastran or equivalent analysis tools
• Perform detailed hand calculations using industry-standard methodologies and references including:
  • Bruhn
  • Niu
  • Roark
  • ESDU
  • Classical mechanics of materials approaches
• Collaborate with loads, design, materials & processes, manufacturing, structural test, and certification teams throughout the entire development process
• Support trade studies and structural design optimization activities
• Define structural analysis requirements and certification substantiation plans
• Review and approve design dispositions and engineering analyses
• Support component, subassembly, and full-scale structural testing activities, including:
  • Test planning
  • Requirements definition
  • Instrumentation support
  • Data review
  • Test reporting
• Prepare structural substantiation reports and certification documentation
• Present structural analyses and recommendations during internal and external design reviews

• Experience in airframe structural analysis supporting aircraft development programs
• Strong knowledge of metallic and composite aircraft structures
• Experience supporting FAA Part 23 and/or Part 25 aircraft certification programs
• Advanced proficiency with FEMAP/Nastran or equivalent finite element analysis tools
• Experience with NX or similar CAD platforms
• Strong understanding of:
  • Aircraft loads
  • Free body diagrams
  • Structural load paths
  • Mechanics of materials
  • Structural stability and failure modes
• Advanced proficiency performing both hand calculations and finite element analyses
• Experience developing structural substantiation reports and certification documentation
• Strong technical writing and communication skills
• Ability to work effectively within multidisciplinary engineering teams
• Strong analytical and problem-solving capabilities

Preferred Qualifications

• Master's degree in Aerospace Engineering, Mechanical Engineering, or related discipline
• Experience supporting aircraft programs from conceptual design through certification and production
• Experience with composite airframe design and certification
• Experience supporting structural testing and correlation of analytical models
• Familiarity with hybrid-electric, eSTOL, eVTOL, or advanced air mobility aircraft programs
• Experience working directly with regulatory authorities during certification efforts
• Experience mentoring engineers and reviewing structural analyses
• U.S. Person (U.S. Citizen or Green Card holder) preferred

Leveling Expectations

Level (Senior or Principal) will be determined based on the candidate's experience, technical expertise, demonstrated leadership, and ability to influence aircraft development decisions. Both levels require expertise in aircraft structural analysis, certification substantiation, and aircraft development. Differentiation is based on technical leadership, scope of responsibility, independence, and organizational influence.
