Structural Engineer - Own the structural design, analysis, and qualification of next-generation spacecraft hardware Denver, Colorado | On-site Opportunity Summary This role will own spacecraft structural hardware from early requirements and detailed design through analysis, qualification testing, production, and on-orbit operation. You will also serve as a technical leader for structural analysis across the program, defining methods, load cases, test requirements, and modeling standards used by the broader engineering team. The work spans primary and secondary structures, mechanisms, integrated assemblies, structural dynamics, finite element analysis, environmental testing, and model correlation. You will remain hands-on with your own hardware while helping establish the structural engineering practices needed as the vehicle and team scale. About Us We are a venture-backed space technology company developing advanced modular spacecraft systems designed to operate, connect, and reconfigure in orbit. The team is small, highly technical, and progressing from flight demonstration toward operational systems. Engineers have broad ownership and work directly on hardware that must survive launch, operate reliably in space, and support increasingly capable spacecraft architectures. Job Duties Own spacecraft structures, mechanisms, and electromechanical assemblies from concept through production and flight Translate system requirements into structural designs, load cases, analysis plans, and qualification requirements Lead structural analysis across the program, including modal, quasi-static, random vibration, sine, shock, buckling, bolted-joint, and thermo-elastic analysis Develop, refine, and post-process finite element models for components, subsystems, and integrated spacecraft assemblies Calculate and document structural margins of safety across launch and on-orbit environments Define structural loads, environments, factors of safety, and verification requirements Lead vibration and structural test campaigns for flight hardware Define instrumentation approaches using accelerometers, strain gauges, and other structural test hardware Correlate analytical models with test data and improve model fidelity based on results Support detailed mechanical design, CAD development, tolerance analysis, and design reviews Work with manufacturing teams and suppliers to develop structures and joints that are producible, inspectable, and testable Create and review engineering drawings using GD&T and aerospace design practices Support structural dispositions, failure investigations, and design changes during development and test Establish structural analysis methods, documentation standards, and engineering best practices Mentor less-experienced engineers and provide technical guidance across the broader mechanical team Qualifications Bachelor's or Master's degree in mechanical engineering, aerospace engineering, or a related technical discipline 5+ years of structural analysis and flight hardware development experience Experience owning spacecraft, launch vehicle, aerospace, or similarly demanding hardware through multiple stages of development Strong proficiency with structural FEA tools such as Nastran, Femap, ANSYS, Abaqus, or comparable platforms Hands-on experience with modal, quasi-static, random vibration, buckling, and joint analysis Strong understanding of launch loads, on-orbit environments, factors of safety, and margin assessment Experience developing and executing structural dynamics or environmental test campaigns Experience correlating analytical models with physical test data Strong CAD capability including 3D modeling, detailed drawings, and tolerance stack-ups Working knowledge of GD&T and
