End-to-End Space Transportation and In-Space Services

Firefly Aerospace is a U.S. based advanced space technology developmental organization focusing on the leading edge of space systems progression. We are committed to providing economical and convenient access to space for small payloads through the design, manufacture, and operation of reliable launch vehicles. If you are great at what you do and would like to work with people who really want to make a difference, then Firefly is the place for you.


Firefly is looking for talented structures engineers to develop our state-of-the-art composite structure throughout the product life cycle. You’ll be part of a highly skilled, dynamic team that will involve you in all aspects of analysis, design, fabrication, and testing. Excellent collaboration and communication skills, along with a positive attitude are critical.


  • Firefly engineers own and influence the entire hardware design cycle including conceptual design, structural layout, sizing analysis, hardware production, and structural testing
  • Composite and metallic Primary structures for orbital launch applications
  • Composite pressurized structures analysis, design, and/or manufacturing
  • Design of structural joints with bonded and bolted configurations
  • Light weighting existing designs and requalifying designs
  • Supporting products from conceptual design, formal design, analysis, protype, qualification and production
  • Support configuration development and trade studies
  • Finite Element Model development, refinement, validation, and postprocessing
  • Maintain requirements, activity schedule, budget, and status
  • Create CAD, manufacturing drawings, specifications, and other documentation
  • Perform first order strength and sizing calculations for your responsible structure



  • B.S. degree in aerospace, mechanical, or civil engineering and 0-5 years of experience in aerospace or related structures engineering.
  • Strong design and integration skills using 3-D CAD software (Siemens NX / FiberSim preferable).
