At Zenith Aerospace, we design, build, and fly large scale unmanned aircraft from the ground up. We recently closed a funding round led by Founders Fund — the first investor in SpaceX — and with the wind in our sails, we want to grow our team with driven, talented, bootstrapping engineers and technicians from diverse backgrounds and paths of life. If you are excited about aerospace, tackling world-class engineering problems, and making big things fly, you are in the right spot. Join us!
We are seeking an Airframe Engineer to join our core design engineering team. In this position, you will be responsible for evolving our aircraft structure architecture, evaluating trade-offs, running sizing and optimizations to meet customer requirements, leading the detailed design and analysis, planning and executing structural testing campaigns, and overseeing structural airworthiness documentation. You will work in a tight feedback loop with the greater Engineering team to promptly iterate through aircraft designs and configurations. Your work will drive the development of cutting-edge unmanned aircraft and take an airplane from its earliest stages of development through iterative process, testing, and, ultimately, manufacturing production in rapid succession. This positions reports to the Head of Aircraft Structures and is an on-site position from our HQ in Belmont, CA.


  • Lay out aircraft structure architectures and evaluate trade-offs on weight, soundness, manufacturability, and cost
  • Run preliminary sizing studies using hand calculations, design tools and optimization scripts
  • Develop the manufacturing plan for parts and assembly of a large UAV airframe
  • Run materials and process testing and data analysis in order to develop composite materials database and process standards
  • Design and build structural test articles to validate airframe joints and critical structural features
  • Take ownership of the airframe CAD model
  • Plan, build, and manage FEA models and simulations
  • Plan building block testing campaigns for model calibration and compliance
  • Interpret certifications and regulations, then establish compliance strategies
  • Generate, review, and approve certification-related documents
  • Collaborate in a multidisciplinary environment in order to solve complex, open-ended problems with an emphasis on speed of execution and efficiency

  • 5+ years of experience in airframe design and sizing for fixed-wing aircraft or rotorcraft
  • Solid mathematics and engineering physics background
  • Excellent understanding of aircraft fundamentals (flight mechanics, aerostructures, loads,…)
  • Expert knowledge and applied experience with composite mechanics, design, analysis, and manufacturing
  • Extensive hands-on experience with composites manufacturing with varying processes (pre-preg, wet layup, infusion, etc.)
  • Proficiency with 3DExperience or CATIA V5/V6
  • Proficiency with SIMULIA / ABAQUS, NASTRAN, SAMCEF, or other FEA analysis tools

Preferred Qualifications:

  • M.S. or Ph.D. in Mechanical Engineering, Aerospace Engineering, or a closely-related Engineering discipline
  • Previous experience working on aircraft certification programs and knowledge of FAA Part 23
  • Knowledge of aeroelastic instabilities (e.g. flutter), and with their corresponding alleviation methods
  • Experience with aeroservoelastic analysis
  • Extensive experience with building block testing approach (pyramid of test)
