At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

This role is part of Advanced Concepts and Enterprise Engineering (ACE), supporting Blue Origin's mission of millions of people living and working in space for the benefit of Earth. The team fosters innovation and drives engineering workflows of the future, shared solutions and standards, simplicity and lower costs, and manufacturable design.

The GN&C Modeling and Simulation Engineer supports integration, verification, analysis, and evaluation of spacecraft GN&C algorithms, vehicle performance, and mission design. Candidates have a strong background in the architecture and capabilities of spacecraft guidance, navigation, and control algorithms, and are able to leverage modern design tools to support rigorous verification of algorithm performance and robustness. A deep understanding of physical modeling, including classical dynamics, astrodynamics, aerodynamics, and propulsion systems along with model-based engineering software development experience is highly desired.

Responsibilities include, but are not limited to:

  • Develop and extend large-scale simulation software; support mission design, trajectory optimization, systems engineering, and test design.
  • Integrate, update, and verify guidance, navigation, and control algorithms.
  • Perform system analyses to satisfy specifications and requirements and to drive system-level architectural decisions.
  • Specific duties are subject to our business unit objectives.

Minimum Qualifications:

  • Minimum of a B.S. degree in physics, aerospace engineering, computer engineering, electrical engineering, mechanical engineering, or other relevant engineering field.
  • Fundamental understanding of dynamics, kinematics, orbital mechanics, estimation, and control theory.
  • Understanding of spacecraft subsystem concepts including rocket propulsion, navigation sensors, and avionics.
  • Practical experience in guidance, navigation, and controls algorithm development and analysis for aerospace applications.
  • Demonstrated ability to apply rigorous analytical methods in verification and analysis.
  • Strong software and model development skills, particularly in one or more of MATLAB, C/C++, Python, and Rust.
  • Ability to work independently and as part of a team on rapid development programs.
  • Flexible and adaptable mindset.
  • Self-driven with the ability to seek out requirements with minimal direction.

Preferred Qualifications:

  • M.S. degree or PhD in physics, aerospace engineering, computer engineering, electrical engineering, mechanical engineering, or another relevant STEM field.
  • Knowledge of multi-body dynamics, flexible body dynamics, gas and fluid dynamics and thermodynamics.
  • Experience with trajectory design and optimization tools such as Copernicus, STK, GMAT, POST and OTIS.
  • Experience developing and verifying physical models for the purpose of control design, component sizing, and system performance evaluation.
  • Experience with Monte Carlo simulation and statistical performance analysis.
  • Experience with simulation development in Trick/JEOD.
  • Experience with software configuration control and quality assurance.
