Astrodynamics Engineer: Master Multibody Dynamics & Data for SDA

The Judge Group; Westminster (CO); On-site; USD 120,000 - 180,000; Full time

Job summary

The Judge Group is seeking an Astrodynamics Engineer in Westminster, CO, to serve as the technical authority for orbital mechanics across SDA programs. You will generate synthetic datasets used to train and evaluate machine-learning models, and review data with respect to physics-based expectations.

Responsibilities include developing dynamical models for two-body through multi-body dynamics, collaborating with research partners, and defining interfaces and validation cases. A U.S.

Qualifications

• MS or PhD in Aerospace Engineering, Astrodynamics, Applied Mathematics, or related field.
• 3+ years of relevant experience; PhD may substitute for part of this requirement.
• Demonstrated orbit determination experience using batch least squares, sequential/Kalman estimators with covariance handling.

Responsibilities

• Build and validate dynamical modeling environments across two-body to multi-body cislunar dynamics.
• Generate synthetic observation datasets for ML model training and evaluation.
• Incorporate ephemerides and reference datasets for independent validation.
• Implement and characterize orbit-estimation chains with proper covariance handling.
• Analyze estimator convergence, observability limits, and custody feasibility.
