Senior GNC Engineer: Spacecraft Propulsion & Guidance

EVONA; California; On-site; USD 180,000 - 240,000; Full time

Job summary

EVONA is seeking a Senior GNC Engineer to design and ship advanced guidance, navigation, and control algorithms for spacecraft propulsion systems. You will implement closed-loop burn strategies, perform stability analyses, and drive hardware-in-the-loop validation across multiple programs.

You will own the GNC codebase, maintain simulation capabilities, and support mission design reviews with robust analysis products, contributing to the company’s growing space systems team.

Qualifications

• Bachelor's degree in aerospace, mechanical, electrical engineering or physics.
• 5+ years of GNC experience on space vehicles with end-to-end ownership.
• Strong MATLAB/Simulink/model-based design experience.

Responsibilities

• Design and implement GNC flight algorithms for spacecraft propulsion systems, including closed loop burn execution, thrust, delta-v estimation, burn targeting, cutoff logic, and trajectory correction maneuvers.
• Own the GNC flight code: architecture, implementation, review standards, configuration management, and verification evidence.
• Develop and maintain 6 degrees of freedom simulation capability for burn execution and dispersion analysis across multiple programs.
• Perform stability analysis of control loops and document it to flight-review standards.
• Define hardware-in-the-loop test campaigns: test objectives, pass/fail criteria, fault injection cases, and test procedures.
• Validate flight software against simulation truth models and HIL results; connect analysis, code, and test.
• Support mission design reviews with GNC analysis products: pointing budgets, execution-error models, and dispersion results.
