Onsite Kennedy Space Center / Florida – No hybrid or remote is available. NASA or AEROSPACE Exp US Citizens or Perm Residents Only

We are looking for a Guidance, Navigation, and Control (GN&C) Engineer to join our team supporting advanced spaceflight programs at NASA Kennedy Space Center. The GN&C Engineer supports the development, analysis, verification, and integration of guidance, navigation, and control systems for spacecraft and other flight systems. This role provides technical support across GN&C, mission design, trajectory analysis, and navigation
, allowing the engineer to contribute across multiple areas based on program needs. This position will be filled at the Journeyman level
, depending on qualifications, with salary commensurate with experience.

Key Responsibilities

• Support GN&C, mission design, trajectory analysis, and navigation activities as needed to address program priorities and fill engineering gaps.
• Review GN&C architectures, requirements, designs, integration approaches, test plans, and test data to evaluate technical adequacy, identify risks, and develop recommendations.
• Develop and execute trajectory, attitude, and 6-DOF spacecraft simulations and perform analysis supporting GN&C performance and mission objectives.
• Support mission design and trajectory analysis
  , including trajectory development, maneuver planning, orbit and attitude analysis, and rendezvous, proximity operations, and docking (RPOD).
• Analyze spacecraft navigation architectures and sensor suites
  , including sensor performance, accuracy, availability, observability, and suitability for GPS-denied and deep-space missions.
• Support navigation analysis involving state estimation, sensor fusion, and interactions between navigation sensors, flight software, guidance algorithms, and vehicle dynamics
  .
• Develop, review, and assess GN&C requirements, verification approaches, and verification evidence in support of system verification and validation.
• Support development, integration, verification, testing, and operation of spacecraft GN&C systems and associated sensors.
• Evaluate GN&C analyses, simulations, technical documentation, and test results to identify technical risks, uncertainties, and potential deficiencies
  , and support anomaly investigations and corrective actions.
• Evaluate technical tradeoffs involving performance, risk, schedule, cost, and implementation complexity and communicate recommendations to engineering and program leadership.
• Analyze GN&C interfaces with avionics, flight software, propulsion, mission design, structures, and other spacecraft systems
  .
• Participate in technical reviews, testing, and engineering exchanges and communicate technical findings and recommendations to technical and programmatic stakeholders.

Required Qualifications

• B.S. degree in Engineering or related discipline and 5+ years of related experience
  , or M.S. degree in Engineering or related discipline and 3+ years of related experience
  .
• Demonstrated experience in one or more areas of spacecraft GN&C, mission design and trajectory analysis, navigation, or related flight dynamics
  , with the ability and interest to contribute across adjacent technical areas.
• Experience developing or analyzing GN&C algorithms and spacecraft simulations, including 6-DOF modeling
  .
• Experience with engineering analysis and simulation tools such as MATLAB, Python, C++, or equivalent
  .
• Experience developing or evaluating spacecraft requirements, verification approaches, and success criteria.
• Experience with spacecraft GN&C systems, navigation sensors, integration, verification, testing, or operations.
• Must be a U.S. Citizen and successfully complete a U.S. Government background investigation.
• Strong communication, organization, and teamwork skills, with the ability to coordinate across multiple technical disciplines.

Preferred Qualifications

• M.S. degree in a related discipline.
• Experience with deep-space missions or GPS-denied navigation
  .
• Experience with spacecraft navigation sensors, state estimation, sensor fusion, or autonomous navigation.
• Experience with mission design, trajectory development, rendezvous/proximity operations, or maneuver analysis
  .
• Experience with spacecraft flexible-body dynamics, propellant slosh, or other spacecraft dynamics effects in low-gravity environments.
• Strong proficiency in C++ and experience developing or using mission-specific GN&C simulation or analysis software.
• Experience with trajectory and mission-analysis tools.
• Experience working with commercial spaceflight or launch service providers.
• Experience with deep-space or other safety-critical spaceflight systems
