About the Job

Requirements

  • At least 2 years of experience in spacecraft structural analysis, primary structures, or structural substantiation roles.
  • Experience performing stress, deflection, buckling, and margin of safety assessments using finite element modeling and hand calculations.
  • Proficiency developing and maintaining structural finite element models using FEMAP/Nastran or Siemens Simcenter 3D.
  • Experience substantiating metallic and composite spacecraft structures, including load path validation.
  • Experience owning or supporting structural verification efforts through analysis and test.
  • Proficiency with Python and/or MATLAB for analysis automation, data reduction, and reporting.
  • Experience using version control systems such as Git in an engineering analysis environment.
  • A Bachelor of Science or Master of Science in Aerospace Engineering, Mechanical Engineering, or a related engineering discipline.

Responsibilities

  • Own the structural finite element model for primary and secondary spacecraft structures and maintain configuration control.
  • Perform stress, deflection, stability, and margin of safety analyses using finite element modeling and first-principles hand calculations.
  • Substantiate metallic and composite structures, including strength, stiffness, and buckling assessments.
  • Develop and document structural verification approaches, assumptions, and acceptance rationale.
  • Support design trades and architecture decisions through analytical assessment of load paths and structural efficiency.
  • Partner directly with design engineers to validate and optimize primary and secondary structural designs for strength, stiffness, weight, cost, and manufacturability.
  • Develop Python-based tools to automate analysis workflows, post-processing, and margin reporting.
  • Collaborate with design, manufacturing, and test teams to resolve structural issues and assess nonconformances.
  • Support structural qualification and acceptance testing, including pre-test predictions and post-test correlation.
  • Contribute to structural documentation, analysis reports, and verification artifacts.

Desired Qualifications

  • Strong ability to perform structural stress analysis and margin of safety calculations for primary and secondary spacecraft structures.
  • Deep understanding of load paths, structural behavior, and failure modes in metallic and composite structures.
  • Ability to build, interrogate, and validate finite element models using first-principles reasoning.
  • Proficiency in developing and applying hand calculations to verify and bound finite element model results.
  • Ability to automate analysis post-processing and verification reporting using Python or MATLAB.
  • Clear technical communication skills for documenting assumptions, methods, and structural substantiation rationale.

About the Company

Portal Space Systems

Develops rapid, solar-thermal propelled satellite buses

Portal Space Systems designs and builds spacecraft for in-space mobility, focusing on a solar thermal propulsion-driven satellite bus called the Supernova. The bus uses solar energy to heat a propellant, delivering higher thrust and efficiency to perform large orbital changes, such as transferring from LEO to GEO or to cislunar space. The team includes veterans from SpaceX, Blue Origin, and Kuiper, helping mature the technology and manufacturing process. The company has secured over $3 million in Department of Defense funding, signaling a government and defense market focus, and plans to begin production of the Supernova by the end of 2026 from its Bothell, Washington base. Its goal is to move satellites more quickly and flexibly through space, enabling expanded space logistics and orbital transfer capabilities while winning government contracts.
