Software Development Engineer Sr

About the role

This role supports the development and operations of New Glenn, a single-configuration, heavy-lift orbital launch vehicle capable of routinely carrying people and payloads to low-Earth orbit, geostationary transfer orbit, cislunar, and beyond. Its first stage is fully reusable, and the vehicle was designed from the beginning to be human-capable.

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
• Coordinate cross-team vehicle-level analyses and trade studies
• Lead root cause investigations and peer reviews of GN&C products

Requirements

• B.S. in aerospace engineering, mechanical engineering, or a related engineering 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

Qualifications

• M.S. or Ph.D. in aerospace engineering, mechanical engineering, or a related discipline (preferred)
• Demonstrated knowledge in both classical and modern control design techniques
• Experience with C/C++ flight software development
• Experience with auto-code generation from Simulink models
• Monte Carlo analysis and statistical methods for performance and robustness characterization
• Experience supporting hardware-in-the-loop or flight test campaigns
• Python scripting for analysis, automation, or data processing
• Familiarity with flight software verification processes (unit testing, code coverage, requirements traceability)
• Experience mentoring junior engineers or leading technical trades across disciplines
