About the Role
As the Stage Fluids Analysis Manager, you will be responsible for a team of analysts providing essential technical guidance for hardware design and operations across fluid dynamics and thermal systems. You will apply deep expertise in internal flow and thermal analysis to guide component, systems, propulsion, operations, and guidance, navigation and control teams.
You will
Manage a high-performing fluids analysis team aligned with program milestones
Define, scope, and schedule required analyses to support program execution
Ensure analysis fidelity is appropriate for each phase of development
Oversee resource planning and analysis progression to meet program timelines
Set clear team goals and drive accountability
Perform thermal-fluid calculations to size and design compressible and incompressible systems using: Hand calculations, custom scripts and simple programs, network solvers & CFD models
Develop and execute CFD analyses for complex vehicle problems, including but not limited to:
Propellant management, dynamics, and thermal stratification
Compressible flow within complex manifolds and components
Multiphase flow within feedlines
Validate and quantify uncertainty in analysis models using literature and test data
Mature internal tools and methodologies for predicting fluids behavior across ascent, in-space, and reentry flight
Mentor engineers and guide hardware owners to ensure systems meet fluid requirements
To succeed in this role, you will bring a solid foundation in fundamental physics and the ability to apply first-principles thinking to complex problems. You are self-motivated, adaptable, and thrive in a fast-paced, highly integrated and collaborative vehicle development environment
This role offers the opportunity to directly influence major engine and vehicle stage hardware while accelerating your professional growth in a culture that values collaboration, ownership, technical rigor, and calculated risk-taking
About You
Bachelor’s degree in engineering or related field and +7 years of relevant experience across at least 1 aerospace vehicle program lifecycle
Proven experience leading high-performing engineering teams delivering successful hardware on complex, cross-functional projects
Demonstrated mentoring and technical leadership skills
Proficiency in Python or a similar programming language for scientific computing and automated test/simulation data analysis
Experience performing 1D modeling of compressible and incompressible flow using hand calculations or fluid network analysis tools (e.g. GFSSP, FloCAD, or equivalent)
Experience in architecting and executing industry-standard CFD tools (e.g., STAR-CCM+, Fluent, FLOW-3D, or equivalent) and workflows to inform hardware design
Nice to haves but not required
Experience building volume of fluid and/or internal compressible flow CFD models
Experience developing simulation toolsets and workflows, e.g. for HPC
