Geodetic Data Modeler at Core4ce – St. Louis, Missouri

Core4ce

Geodetic Data Modeler
1053-383

We are seeking a candidate who is highly knowledgeable in Geodesy with deep expertise in science and theories governing the Earth’s geometry, orientation, motion, and physical fields. The ideal candidate will understand how the size and shape of the Earth are measured and modeled, how the planet moves through space, and how its gravitational and magnetic fields behave and evolve over time. This role supports advanced research, analysis, and mission applications that rely on precise Earth modeling and geophysical insight.

Key Responsibilities:

• Apply advanced geodetic theory to characterize and model the Earth’s size, shape, and physical properties.
• Analyze Earth orientation parameters, rotational dynamics, and orbital motion as they apply to mission and system requirements.
• Interpret and model gravitational and magnetic potential fields and their temporal variations.
• Support the development, refinement, and validation of geodetic reference frames, Earth system models, and geophysical datasets.
• Provide expert consultation to government stakeholders, mission planners, and technical teams on geodesy-related impacts to systems, sensors, and analytic workflows.
• Prepare technical reports, briefings, and recommendations for both technical and non-technical audiences.

*This position is designed to be flexible, with responsibilities evolving to meet business needs and enable individual growth.

Required Qualifications:

• Degree in geological sciences, geodesy, geophysics, physics, or quantum physics.
• TS/SCI (will need to obtain a CI Poly)
• Strong knowledge of geodesy, Earth system science, or related geophysics disciplines. Understanding of Earth shape, gravity models, magnetic field theories, and Earth orientation/rotation dynamics.
• Experience applying geodetic or geophysical principles to scientific, analytic, or operational problems leveraging interpolation methods, kriging and least square colocation.
• Ability to interpret complex geophysical datasets and communicate findings clearly.
• Experience with geodetic reference frames, satellite geodesy, GNSS, or gravity/magnetic modeling.
• Familiarity with IC or DoD mission areas that rely on precise Earth modeling.
• Experience with Python, MATLAB, GIS software (ArcGIS Pro/GIS applications).
• 5 years of relevant experience and a BA/BS degree. OR a MA/MS degree and 3 years of relevant experience; OR a PhD degree.
