The successful candidate will communicate effectively with team members and internal stakeholders, as well as participate in authoring content, patents, and. As such, excellent written and verbal communication skills are required.
JOB DUTIES AND RESPONSIBILITIES
- Lead and conduct research in astrodynamics, GNC and orbit prediction, space weather, and space domain awareness (SDA) leveraging machine learning and advanced numerical methods.
- Design and develop high-fidelity GNC and astrodynamics models for high-performance FPGA-based computing platforms and space-grade embedded systems; collaborate with the broader engineering team to ensure their successful implementation.
- Apply advanced AI/ML algorithms such as physics-informed neural networks for system identification, sensor fusion, and autonomous decision-making in space environments.
- Serve as the Principal Investigator on complex GNC research efforts; manage technical milestones, and interdisciplinary teams.
- Lead proposal writing efforts and assist secure external research funding from federal agencies, commercial partners, and international organizations.
- Mentor early-career GNC engineers, postdocs, and graduate researchers; foster a collaborative and technically rigorous environment.
- Perform technical analyses to support space operations, including but not limited to the analyses of satellite conjunctions, deployment events, and maneuver detection; develop algorithms for autonomous monitoring and alerting.
- Lead technical interface with commercial and government customers; prepare and deliver high-impact presentations, status updates, and briefings.
- Publish research in leading journals and conferences; represent the organization in international technical fora and strategic collaborations.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
- Ph.D. in Aerospace Engineering, Applied Physics, or a related discipline from an accredited institution with an emphasis on GNC, astrodynamics, or AI/ML applications in space.
