Job description

Company Overview:  

A rocket company at the core, Relativity Space is on a mission to become the next great commercial launch company. Meeting the needs of a growing demand for space infrastructure, our rockets will revolutionize how we connect and communicate on Earth by getting satellites to space. We have developed a vertically integrated technology platform in which we leverage additive manufacturing, artificial intelligence, and autonomous robotics to 3D print rockets. Our unique approach enables rapid product iteration, allowing us to push the boundaries of what's possible today and unlock the full potential of 3D printing for tomorrow. Join us on this extraordinary journey, as we work together to transform our vision into reality.


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

This is an entry-level technical role in the Flight Sciences team within the Integrated Performance department. We have multiple roles available in each of our sub-teams, such as Aerodynamics, Aerothermodynamics, Thermal, Loads & Dynamics, and Dynamic Environments. Each group is responsible for the success of our rockets and ground systems in its domain of physics. Day to day, Flight Sciences engineers work on design, analysis, test, and tools development projects across every launch system, from launch pads to engines to avionics and beyond.

What you’ll do: 

  • Build models of the Terran R vehicle and ground systems for detailed analysis in FEA, CFD, SEA, or thermal simulation tools
  • Team up with structures and avionics designers to develop a scalable, robust architecture for component installation and environmental isolation
  • Perform multibody dynamics analysis to simulate behavior during vehicle stage separation
  • Develop software tools to efficiently process thousands of individual analyses in a Monte Carlo simulation
  • Develop existing or new code to automate simulation, data analysis, and signal processing
  • Analyze Terran 1 flight data to correlate with analytical and empirical predictions
  • Generate forcing functions for liftoff, aerodynamics, and engine-borne dynamic excitation
  • Perform transient dynamic analysis in support of Coupled Loads Analysis (CLA)
  • Support vibration and shock or thermal testing of components

What you need to know:  

  • An undergraduate degree in engineering or related field and practical engineering experience, e.g., from project teams, internships, or research labs
  • Passion for launch vehicles and spacecraft
  • Experience solving challenging technical problems in teams
  • Familiarity with Python or another scripting language like Matlab

Nice to haves but not required:  

  • A graduate degree (MS/PhD) in engineering or related field
  • Familiarity with launch vehicles and liquid rocket propulsion


Relativity Space offers competitive salary and equity, a generous vacation policy, an annual L&D stipend and more! 

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.
