What are the key skills and qualifications needed to thrive in the Multiphase Flow position, and why are they important?

To thrive in a Multiphase Flow role, you need a solid background in fluid mechanics, chemical or petroleum engineering, and experience with modeling and analyzing complex fluid systems. Familiarity with simulation software like ANSYS Fluent, OLGA, or COMSOL, as well as relevant certifications such as PE (Professional Engineer), are often required. Strong problem-solving skills, attention to detail, and effective teamwork and communication abilities are key soft skills for success. These skills are vital for accurately predicting flow behaviors, optimizing processes, and ensuring safety and efficiency in industries such as oil and gas or chemical engineering.

What is a Multiphase Flow job?

A Multiphase Flow job involves the study and analysis of fluids consisting of multiple phases, such as gas-liquid, liquid-solid, or gas-solid interactions. Professionals in this field work in industries like oil and gas, chemical processing, and aerospace, using computational simulations and experimental methods to optimize system performance. They may focus on fluid dynamics, heat transfer, pipeline transportation, or reactor engineering. This role requires expertise in physics, engineering, and numerical modeling tools like CFD (Computational Fluid Dynamics).

What are some typical daily responsibilities of a Multiphase Flow Engineer?

A Multiphase Flow Engineer typically spends their day analyzing and modeling how different phases (such as oil, gas, and water) interact within pipelines or processing systems. This involves running simulations, interpreting data from field sensors, preparing technical reports, and collaborating with multidisciplinary teams to solve operational challenges. Engineers in this role also participate in design reviews, troubleshoot flow assurance issues, and recommend optimizations to improve efficiency and safety. The balance between simulation work, data analysis, and cross-functional collaboration provides a dynamic and engaging work environment.

Job description

At Relativity Space, we're building rockets to serve today's needs and tomorrow's breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that's just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven't been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you're in propulsion, manufacturing, software, avionics, or a corporate function, you'll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we're writing together. Now is a unique moment in time where it's early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

About the Team:

The Stage Fluids team designs and delivers the propellant, pressurant, pneumatics, and other fluid systems that turn structures into functioning rockets. The team has full ownership across design, production, test, and flight, maintaining a holistic view of Terran R, focused not on isolated parts but integrated functionality. Working on-site at the factory means you're never far from the hardware, enabling rapid iteration and tight feedback loops across design and manufacturing. You won't just be handed requirements: you'll be expected to ask the right questions, collaborate with partners across the company, and ultimately find the best solutions for Terran R.

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
