Moonshot Aerospace is seeking a GN&C Test & Verification Engineer to support spacecraft test and integration activities at a customer site in Houston, TX. This position supports validation and verification (V&V) of GN&C and positioning, navigation, and timing (PNT) subsystems for commercial and government programs including the Human Landing System (HLS), Commercial Lunar Payload Services (CLPS), and related efforts.

This role combines GN&C domain knowledge with hands-on test planning and execution. The engineer will lead or support V&V testing on flight-like hardware and high-fidelity testbeds, translate requirements into verification strategies, and drive test activities from planning through final reporting. This is an on-site position at the customer facility. Multiple experience levels are available, and responsibilities will scale with demonstrated capability.

Responsibilities

• Plan and execute V&V testing for GN&C and PNT hardware and software components

• Organize and lead test execution, including scheduling, coordinating required personnel, and documenting results

• Translate system and subsystem requirements into executable test plans and verification strategies

• Prepare and lead Test Readiness Reviews (TRRs)

• Serve as test conductor for integrated testing activities, managing anomaly resolution and troubleshooting

• Perform post-test analysis and generate test reports with clear documentation of results and findings

• Support GN&C hardware integration including GNSS receivers, navigation sensors, optical cameras, and flight software

• Conduct requirements analysis and flow-down, ensuring alignment with mission objectives and applicable standards

• Generate and maintain technical documentation including: test plans, procedures, and interface control documents

• Collaborate with multidisciplinary teams across avionics, electrical, mechanical, software, and GN&C disciplines

Required Qualifications

• U.S. Citizenship and ability to obtain and maintain a security clearance

• Broad technical understanding across avionics, electrical, mechanical, and software systems

• Strong organizational skills and ability to coordinate test activities across multiple teams

• Effective written and verbal communication skills

Preferred Qualifications

• M.S. in Aerospace Engineering, Electrical Engineering, or related field

• Experience with GN&C or navigation sensor testing (IMU, star tracker, GPS/GNSS, LiDAR, optical cameras)

• Hardware-in-the-loop (HWIL) or software-in-the-loop (SWIL) test experience

• Background in spacecraft integration and test (I&T) environments

• Experience with autonomous systems, navigation, or PNT subsystems

• Familiarity with requirements management and traceability tools

• Experience with JIRA, Agile processes, and configuration management

• Spacecraft flight operations or real-time test execution experience
