• Develop engineering analyses, models, and technical documentation supporting propulsion system and hardware development
• Analyze propulsion and fluid system performance and provide technical recommendations based on modeling and simulation results
• Collaborate with multidisciplinary engineering teams to deliver propulsion solutions that meet technical and program objectives
• Investigate propulsion system and hardware anomalies, perform root-cause analysis, and develop technically sound recommendations
• Contribute to the development of propulsion engineering standards, analytical best practices, and continuous process improvements
• Support technical reviews including System Requirements Review (SRR), Preliminary Design Review (PDR), Critical Design Review (CDR), Test Readiness Review (TRR), and Flight Readiness Review (FRR)
• Operate within a fast-paced development environment focused on rapid execution, technical excellence, and mission success

What It Takes

• Bachelor's, Master's, or Ph.D. in Aerospace Engineering, Mechanical Engineering, or a related engineering discipline
• 3+ years of experience working with propulsion systems, fluid systems, or related aerospace applications
• Experience developing and executing piping network analyses using commercial analysis tools such as SINDA/FLUINT or GFSSP
• Experience developing and executing Computational Fluid Dynamics (CFD) Volume of Fluid (VOF) and plume analyses using commercial CFD tools such as ANSYS Fluent or STAR-CCM+
• Demonstrated ability to independently execute complex technical analyses while collaborating effectively with engineers and cross-functional stakeholders
• Strong analytical, problem-solving, and communication skills

Nice-to-Have Experience

• Experience designing spacecraft propulsion systems, fluid systems, propellant tanks, pumps, or related aerospace hardware
• Experience integrating spacecraft propulsion systems or related fluid system hardware
• Experience planning, executing, or supporting propulsion system or component testing and qualification
• Experience leading significant engineering tasks supporting the development of propellant tanks, pumps, or spacecraft propulsion systems
• Experience performing Finite Element Analysis (FEA)
