Rendezvous and Proximity Operations Oversight Software Engineer

Amentum • Houston, TX

7d • Onsite

About The Position

The Rendezvous and Proximity Operations Oversight Software Engineer will work on the JETS ISS Rendezvous, Proximity Operations, and Capture (RPOC) Team, providing technical oversight, program integration, and certification of International Space Station visiting vehicle Guidance, Navigation, and Control (GN&C) systems in support of ISS missions. The position involves reviewing analyses, test reports, hazard reports, and verification evidence; assessing visiting-vehicle GN&C performance and compliance; and supporting operational planning and real-time mission monitoring.

The role works collaboratively with engineering, safety, flight operations, crew office, and visiting vehicle personnel, as well as NASA civil servants and contractor employees. The position is generally based in an office environment, though work may be indoors or outdoors depending on the task. Regular attendance is critical, and the employee may need to work outside the normal schedule and adjust hours for peak periods and surge requirements. This opportunity is with Amentum, working with NASA and teammate company Intuitive Machines. Proof of U.S. citizenship or permanent residency may be required, and the selected candidate must be able to complete a U.S. government background investigation.

Requirements

• Typically requires a bachelor's degree in Engineering and 2–5 years of experience in the field or a related area.
• Experience with orbital mechanics and GN&C principles.
• Understanding of orbit, entry, descent, and landing GN&C principles.
• Knowledge of GN&C algorithm development and spacecraft system analysis.
• Experience designing, verifying, testing, and operating GN&C hardware and software.
• Experience with Linux, Python, and C/C++.
• Experience developing space-system requirements and documents.
• Strong interpersonal skills for effective work on a collaborative engineering team.
• Ability to organize and prioritize tasks to meet deadlines and schedules with limited supervision.
• Excellent communication, documentation, and presentation skills.
• Ability to work in a team environment with NASA civil servants and contractor employees.
• Experience with Microsoft Office products.
• Ability to meet regular attendance requirements and adjust the schedule for peak periods and surge requirements.
• Ability to complete a U.S. government background investigation; proof of U.S. citizenship or U.S. permanent residency may be required.

Nice To Haves

• Master's degree in Aerospace Engineering focused on GN&C, flight controls, and orbital mechanics.

• Working knowledge of NASA, JSC, and ISS standard practices and requirements, including safety.
• Experience with NASA flight operations and procedures.
• Familiarity with NASA/JSC documentation databases and SharePoint sites.
• Experience with MATLAB and Simulink toolboxes.
• Experience with NASA Trick simulation architecture and JEOD (JSC Engineering Orbital Dynamics).
• Experience with Git/GitLab version control.

Responsibilities

• Certify GN&C system requirements compliance by reviewing analysis and test reports, including assessments of sensor performance, trajectory dispersions, and other GN&C parameters.
• Certify compliance with fault-tolerance safety requirements by reviewing GN&C-related hazard reports and verification evidence, and communicate issues to a Safety Review Panel.
• Identify and recommend solutions to GN&C and rendezvous/proximity operations performance issues.
• Communicate the status of compliance reviews to ISS program management.
• Conduct performance assessments of visiting-vehicle GN&C data for program compliance.
• Review Monte Carlo trajectory analyses using independent six-degrees-of-freedom simulations.
• Provide input to operational products, including flight rules and on-orbit demonstration plans.
• Provide visiting-vehicle GN&C mission console support during real-time ground monitoring.
