We have an exciting opportunity for a
Terrain Relative Navigation Engineer to join our ESSCA contract team at
NASA Marshall Space Flight Center in Huntsville, AL. If selected you will: - Architect and lead improvements to the TRN camera image rendering and simulation pipeline (Terragen / Unreal Engine).
- Design, configure, and optimize rendering pipelines for high-efficiency in-the-loop GN&C simulation; oversee lighting map generation and pre-rendered lighting strategies.
- Provide technical leadership on high-fidelity lidar, laser altimeter, IMU, and star tracker sensor modeling and on lidar-based TRN / HDA algorithm development, analysis, and validation (including motion-compensated terrain scans and CONOPs trades).
- Lead 6-DOF simulation framework development, Monte Carlo analysis, navigation filter implementation, and GN&C/flight software integration.
- Guide software development and optimization (Python, C/C++, MATLAB/Simulink); mentor junior engineers.
- Direct verification, validation, independent technical assessments, documentation, and high-level briefings.
- Interface with GN&C leads, NASA stakeholders, and multi-discipline teams.
Required Qualifications:- Must be a US Citizen and have a STAR IC.
- Bachelor's degree in Aeronautics & Astronautics, Aerospace Engineering, or related field from an ABET-accredited institution (Master's or PhD preferred).
- Significant, demonstrated experience leading or contributing to Terrain Relative Navigation (TRN), lidar-based TRN, optical navigation, and/or HDA systems, including modeling of motion-compensated lidar scans and algorithm iteration.
- Extensive experience developing high-fidelity sensor models (lidar, laser altimeter, IMU, star tracker) and integrating them into 6-DOF simulation environments for lunar lander applications.
- Expert-level proficiency in Python, C/C++, and MATLAB/Simulink; strong background in software & simulation integration and modeling & simulation.
- Proven track record supporting flight-critical lunar lander GN&C development (CLPS, HLS, or equivalent), including Monte Carlo analysis and navigation filter work.
Desired Skills:- Publications on lidar-based Terrain Relative Navigation or visual odometry.
- Experience with Terragen, Unreal Engine, GIS products, Lunar DEMs, albedo maps, lighting models, and camera simulation pipelines.
- Advanced navigation filter design (EKF, SDINS, multi-body gravity, state-replacement architectures).
- Leadership in integrated customer/contractor teams, technical mentoring, and delivery of conference-quality technical products.
- Linux, Git, excellent communication, and a demonstrated ability to rapidly master and apply advanced GN&C concepts.
Benefits:- Competitive pay
- Positive work-life balance
- 100% Employer paid insurance including: Medical, dental, vision, life insurance, accidental death and dismemberment, short-term disability, and long-term disability
- 11 paid holidays annually
- Generous PTO
- 401k after 12 months of service with employer match
- Education assistance
- Relocation assistance (if applicable)
