About this role

Job title: Early Career Spaceflight Hardware Propulsion Engineer

Are you passionate about human space exploration, understanding the origins of the universe, and working with a passionate and diverse team to make a difference? If you are, we need you!

We need your talent, teamwork, and energy to help us achieve great things that inspire people all over the globe. We need you to bring creative ideas and diverse backgrounds to help us envision, shape, and deliver systems that will enable the exploration of space while benefiting people here on Earth. We are excited about what we do, and we need you on our team as we take on exciting challenges for NASA’s pursuits in deep space exploration. As NASA’s largest engineering solutions provider working together with NASA at centers across the United States.

We have an exciting opportunity for a Early Career Spaceflight Hardware Propulsion Engineer to join the JETSII Contract!

The Early Career Spaceflight Hardware Propulsion Engineer will:

  • Apply fluid mechanics, thermodynamics, heat transfer, materials, structures, and machine-design principles to propulsion and spacecraft pressure systems.

  • Support the design and analysis of propulsion-system components and assemblies.

  • Perform or review fluid-flow, pressure-system, thermodynamic, and thermal analyses.

  • Develop models, calculations, and data-analysis tools using Python, MATLAB, or similar engineering software.

  • Develop or review engineering drawings and three-dimensional models using CAD software.

  • Support system architecture studies and technical trade assessments.

  • Assist with the selection of materials, components, fabrication methods, and assembly processes.

  • Participate in propulsion-hardware assembly and integration, including work in laboratory or cleanroom-like environments.

  • Support component- and system-level test planning, execution, and data analysis.

  • Assist with acceptance, qualification, environmental, and space-representative testing.

  • Review test data, technical reports, drawings, requirements, and verification documents.

  • Help investigate hardware anomalies, nonconformances, and unexpected test results.

  • Support the preparation and closure of action items, variances, hazard reports, change documentation, and other certification products.

  • Assess how component designs, changes, or anomalies may affect the propulsion system or spacecraft.

  • Support compliance with pressure-system safety, hardware cleanliness, and contamination-control requirements.

  • Assist with propulsion-system integration into spacecraft or test vehicles.

  • Participate in mission simulations, vehicle checkouts, console activities, or flight operations as assigned.

  • Coordinate technical work with engineers, technicians, analysts, project personnel, suppliers, and contractor organizations.

  • Prepare and present clear technical status updates, analyses, and recommendations.

  • Travel to supplier, test, integration, launch, or program locations when required.

  • Perform other duties as required
