Company Overview:

Relativity is the first and only company to automate aerospace manufacturing by integrating intelligent robotics, software, and proprietary metal 3D printing technology. Disrupting 60 years of aerospace, Relativity offers a radically simplified supply chain, building a rocket with 100x fewer parts in less than 60 days. Our long-term goal is to upgrade humanity’s industrial base on Earth and on Mars.

Team:

The Vehicle Engineering Team is responsible for the design, analysis, and validation of our launch vehicle. As a Fluids Engineer, you will be solving the toughest thermal fluids challenges on the rocket as part of a world-class engineering hardware team.

You will work collaboratively with propulsion, GNC, manufacturing, test, launch, and other teams to design all fluids systems necessary to successfully launch and recover a rocket. A high degree of autonomy along with an ability to prioritize work in our fast-paced environment is required. We believe varied perspectives & backgrounds strengthen our team. Prior experience in aerospace is not required

What you’ll do:

You will play a key role developing the architecture of the upcoming Terran R vehicle. You will address the most complex analytical fluids challenges on the rocket. You will need to think creatively to leverage our additive technology to integrate the design in a way that reduces mass, part count, processes and tooling required.

Here are some examples of projects you could be working on:

• Perform analytical thermal fluid calculations to size and design compressible and incompressible fluid systems using a variety of approaches (hand calcs, simple programs, network solvers, CFD models, etc)
• Anchor models with data from test and launch
• Sizing at the system and component level
• Conducting trade studies to produce architectures and designs that satisfy system requirements
• Design fluid systems to be operated on Earth and in space
• Analyze complex thermal fluid problems like slosh, water hammer, transient events, phase changes, etc.
• Coordinate with GNC teams to assess integrated rocket performance
• Create tools to enhance our team’s analysis capabilities and streamline workflow

To be successful in this role, you must be self-motivated and able to lead projects to completion with limited direction. A high degree of drive and autonomy is required. You must be flexible to changes in strategic direction and willing to go the extra mile to ensure we as a company are producing the best possible product. You will be directly responsible for mission-critical systems and processes as a technical authority for fluid systems. Along with these high expectations comes the opportunity to have a significant influence on a fast-growing startup company and to oversee rapid progress in an environment that encourages growth and risk.

What you need to know:

• Undergraduate degree in engineering or related field
• 4+ years of relevant technical experience**
• Demonstrated ownership, accountability, and success in delivering complex products with minimal guidance
• Strong engineering fundamentals in thermodynamics, fluid dynamics, and heat transfer
• Experience with one or more fluid or thermal modeling tools for internal compressible and incompressible analysis
• Familiarity with programming languages such as Matlab, Python, or C++
• Proven ability to practically apply engineering fundamentals to solve real, complex problems
