 Team and Role Overview:

At Relativity, we reimagine the way rockets are built and flown. We are seeking a highly talented Thermal Structural Analysis Engineer to help us achieve our ambitious goal of launching a 3D printed rocket. This position will provide outstanding technical support in the development of the Aeon 1 propulsion system, as well as contributing to a world-class propulsion team. A high degree of autonomy and leadership is required.


The Mission/Outcomes and Objectives:

To support our mission of changing people’s conception of the way rockets are built and flown, you will perform detailed thermal and structural analysis of propulsion system components using finite element analysis (FEA) and hand calculations. You will work closely with a multidisciplinary propulsion team to optimize engine hardware components for structural integrity, life, performance, weight, and cost.

The projects you’ll be responsible for could include the following:

  • Stress analysis (linear and non-linear, including plasticity and contacts)
  • Thermal analysis (convective heat transfer boundary condition development)
  • Regeneratively Cooled Combustion Chamber and Heat Exchanger design
  • Dynamic analysis (including transient, harmonic, random vibration, shock, rigid and flexible body dynamics)
  • Fatigue, fracture, and damage tolerance analysis
  • Improving and streamlining thermal and structural analysis methods and best practices

Candidate Profile: (Who is the person we are looking for?)

In order to be successful in this role, you should be someone who thrives in ambiguity and is able to lead their own projects into completion. Ideally, you are someone who has come from a fast paced, aerospace environment, having completed difficult projects while collaborating effectively with other key groups.


Minimum Required Skills and Competencies: 

  • An undergraduate or graduate degree (BS/MS/PhD) in engineering or related field
  • Strong understanding of solid mechanics and statics (thermal/mechanical) fundamentals
  • Proficient in finite element modeling and stress analysis (aerospace preferred)
  • Proficient in Ansys, Abaqus, Nastran or similar finite element analysis software (Ansys preferred)
  • Ability to work in a fast-paced and intense startup environment
  • Ability to complete projects with ownership of end-to-end solutions and minimal oversight

Preferred Skills and Competencies: 

  • Graduate degree (MS/PhD) in engineering or related field and 2+ years relevant experience
  • Experience with nonlinear finite element analysis: plasticity and creep
  • Experience with structural dynamics: rigid and flexible body dynamics, modal, random vibration, rotordynamics
  • Familiarity with industry-standard propulsion design and analysis codes (Sinda/Fluint, RTE, etc.)
  • Experience in thermal analysis modeling and boundary condition development
  • Experience with fluid mechanics and CFD (CFX, Comsol, Fluent, Star-CCM+, etc.)
  • Experience with Regeneratively Cooled Combustion Chamber, fluid system, and heat exchanger design and analysis
  • Experience with fatigue, fracture, and damage tolerance analysis
  • Python or Fortran proficiency
  • Good understanding and experience working with additive manufacturing techniques
  • Experience with CAD software (NX preferred)
  • Experience presenting analytical results and making suggestions for design or performance improvements


This position must meet Export Control compliance requirements, therefore a United States Person as defined by 22 C.F.R. § 120.15 is required.

 We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

An Insider's view of Relativity Space

What’s the vibe like in the office?

Our office is very interesting--from the large and colorful art pieces on the walls to the large (and small) rocket parts all over. We also have screens all over that are casting live streams of our testing and manufacturing floor. You just feel like you are seeing the future of manufacturing unfold right before your eyes.

Nat

Lead Recruiter

What is your vision for the company?

We are creating an entirely re-imagined process to iterate and scale rockets quickly, eventually helping to build the future of humanity in space.

Tim

CEO and Co-Founder

What are some things you learned at the company?

I've never been at a company before that has so valued recruiting and the candidate experience in all stages of the interview process, from initial contact to even past onboarding. Everyone here respects each others' time and takes hiring very seriously. We have a high bar, but that means we've also cultivated a very talented team!
