Senior Guidance & Control Engineer, Spaceflight Systems

Blue Origin; Merritt Island (FL); On-site; USD 130,000 - 190,000; Full time

Job summary

Blue Origin in Merritt Island, Florida, is seeking an experienced aerospace engineer to own guidance, control, and sequencing algorithms for the New Glenn program. You will design and implement flight software in C/C++, develop models in MATLAB/Simulink, and perform robustness analyses.

This role emphasizes end-to-end lifecycle ownership from requirements through hardware-in-the-loop, with emphasis on verification, unit testing, and cross-team collaboration to ensure safe, reliable spaceflight.

Qualifications

• B.S. in aerospace engineering, mechanical engineering, or a related discipline.
• 7+ years of experience in aerospace guidance and control or simulation.
• Proficiency in MATLAB/Simulink for algorithm design and analysis.
• Experience designing, testing, and flying aerospace guidance and control systems.
• Strong technical writing and verbal communication skills.

Responsibilities

• Design and develop guidance and control algorithms for New Glenn flight control.
• Sequence mission activities and vehicle system commands.
• Develop GN&C requirements with flow downs to subsystem and software levels, including companion verification methods.
• Build guidance and control algorithms in Simulink to support auto-code generation to target.
• Implement hand-coded flight software in C/C++ where appropriate.
• Conduct stability and performance assessments including development of linear and nonlinear models.
• Perform Monte Carlo simulation campaigns to characterize algorithm performance and robustness across dispersed environments.
• Author and execute unit tests, ensure code coverage standards, and support formal verification activities.
• Support hardware-in-the-loop integration and test campaigns.
• Validate plant models and algorithm performance using test and flight data.
