Hypersonics GNC Engineer: Flight Controls & Simulation

Aleron; Leander (TX); On-site; USD 140,000 - 165,000; Full time

Job summary

Aleron seeks a GNC Engineer in Leander, TX to develop GNC and simulation software for high-speed flight regimes and to perform dynamic analyses across diverse trajectory profiles. You will support mission operations while building breadth across multiple vehicle programs.

This role offers hands-on experience with launch vehicle ascent guidance, hypersonic guidance algorithms, attitude control in high dynamic pressure environments, and real-time flight operations in a fast-paced environment.

Qualifications

• Bachelors degree in a relevant engineering or physics field required.
• Minimum 2+ years in aerospace guidance, navigation, and control.
• Minimum 2+ years of Python for scripting, data analysis, and visualization.
• Minimum 2+ years of hypersonic experience and trajectory/missions design.

Responsibilities

• You will deepen your technical capabilities in flight mechanics and controls, with emphasis on hypersonic applications, taking ownership of system elements and software tools supporting the client's expanding vehicle portfolio.
• Develop and validate GNC software to ensure successful mission execution across multiple vehicle programs.
• Design and tune attitude determination and control algorithms for all flight phases: boost, ascent, and terminal.
• Perform 6DOF dynamic analysis of nominal and dispersed trajectories including heating effects and range optimization.
• Develop and maintain simulation models for aerodynamics, hypersonic thermal constraints, propulsion, sensors, and actuators.
• Create tools to automate workflows, process flight data, and generate technical reports for vehicle performance.
• Conduct stability analysis, sensitivity studies, and hardware-in-the-loop testing of GNC systems under flight conditions.
• Interface with cross-discipline teams to integrate GNC software with vehicle hardware.
• Support trajectory optimization and targeting for mission profiles including launch vehicles and high-speed flight regimes.
• Serve as a GNC console operator for vehicle launch operations and post-flight analysis to improve models.
• Author technical documentation and analysis reports communicating GNC concepts and results.
