Company Overview:

We invented a new approach to design, build, and fly our own rockets, starting with Terran 1 – the world’s first 3D printed rocket and Terran R our reusable next generation 3D printed rocket.

Using our vertically integrated technology platform, leveraging additive manufacturing, artificial intelligence, and autonomous robotics to deliver superiority over traditional aerospace manufacturing methods, we’re disrupting 60 years of aerospace with our novelty approach to get to space, Mars, and beyond faster, more cost-effective, and more reliable.

We believe in a future where interplanetary life fundamentally expands the possibilities for human experience. Our long-term vision is to upgrade humanity’s industrial base on Earth and on Mars.

Team:

The Integrated Performance team at Relativity Space is responsible for ensuring that our rockets will achieve our overall objectives. Our department comprises teams responsible for Flight Sciences, including Aerodynamics, Thermal Science, Loads, and Dynamics; Vehicle Simulation & Performance; Guidance, Navigation, and Control (GNC); and Systems Engineering. We architect and execute analysis, simulation, and test projects for all of Relativity’s hardware and software teams in pursuit of mission success, and ensure that our designs and practices meet stringent customer and government requirements. Overall, this team is critical to the launch success of Terran R.

What you’ll do:

As a Thermal Engineer, You will work collaboratively with the Stage Engineering, Additive, Propulsion, Avionics, and Test teams to deliver thermal analysis and test projects on time and budget, while meeting our technical requirements. A high degree of autonomy along with an ability to prioritize work in our fast-paced environment is required.

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

  • Drive the architecture, sizing, and development of thermal systems like insulation, heaters, thermal protection, and environmental conditioning in collaboration with peer technical teams
  • Build, execute, and validate thermal analyses at the component, sub-system, and vehicle level, including relevant tool development and automation
  • Direct design and development engineers in the successful application of thermal sciences to achieve system and component requirements
  • Develop and execute tests to support thermal systems development and qualification, including hands-on work like test article integration, instrumentation setup, and data processing
  • Support vehicle and engine thermal system development and stage testing as well as flight operations

In order to be successful in this role, you should be self-motivated, adaptable and able to deliver in a fast-paced, integrated vehicle program. You should also be able to resolve ambiguity and drive tasks to completion. Ideally, you have thermal or fluids analysis experience as well as a proven track record completing projects successfully as part of a technical team. This position is ideal for engineers looking to make a direct impact on a variety of mission-critical systems and processes as a key member of a small team.

On a weekly basis, you will be performing analysis, directing design teams, supporting testing, and processing data. You will also use your strong organizational skills to properly manage the documentation and communication of your actions, recommendations, and decisions.

What you need to know:

  • An undergraduate degree in engineering or related field
  • 7+ years experience in thermal analysis
  • Proficiency in component- and system-level thermal and fluids analysis, using relevant toolsets like Sinda/Fluint / Thermal Desktop and other commercial FEM/FDM/FVM solvers
  • Experience in an analysis role on an integrated vehicle program
  • Hands-on experience with writing test plans and performing testing, instrumentation, and data analysis at the component and system level
  • Experience with start to finish design cycles of multiple vehicles
  • Experience solving complex problems on integrated vehicles with design teams
  • Experience with an engineering scripting language like MATLAB or Python

Nice to haves but not required:

  • A graduate degree (MS/PhD) in engineering or related field and 10+ years relevant experience
  • Familiarity with liquid rocket engine architectures and operations
  • Understanding of aerodynamics
  • Experience with launch vehicle thermal protection system materials and thermal protection system sizing
