Job ID: 10537072 | Amazon Kuiper Manufacturing Enterprises LLC

Export Control Requirement

Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Key job responsibilities

• - Design, implement, and validate orbit determination (OD) and clock estimation algorithms, including Extended Kalman Filters (EKF), Batch Least Squares, Square-Root/Sigma-Point Kalman Filters (SKF), and Factor Graph Optimization (FGO) approaches
• - Develop inter-satellite link (ISL) navigation and time-transfer measurement models, including range and range-rate
• - Evaluate and integrate emerging estimation techniques (batch/sequential estimation, robust filtering, multi-sensor fusion) to improve positioning and timing accuracy
• - Design and build simulation and analysis frameworks (e.g., Monte Carlo CONOPS studies) to characterize filter performance, covariance realism, and convergence behavior
• - Collaborate with cross-functional teams to ensure estimator outputs meet mission-level accuracy requirements
• - Conduct performance analysis and troubleshooting of estimation algorithms across distributed constellation and ground infrastructure

Basic Qualifications

• - Experience investigating the feasibility of applying scientific principles and concepts to business problems and products
• - Experience in complex problem solving, and working in a tight schedule environment
• - Master's degree in Electrical Engineering, Aerospace Engineering, or a related field, and 4+ years of research experience in academia, industry, or government
• - Experience analyzing both experimental and observational data sets
• - Experience with data analysis tools such as Matlab or Python
• - Proven experience developing and tuning estimation algorithms (Kalman filtering, batch least-squares, or factor graph optimization) for navigation or metrology applications
• - Experience with orbit determination, sensor fusion, or state estimation for dynamic systems

Preferred Qualifications

• - PhD in a relevant field
• - Experience with GNSS-based orbit determination or precise point positioning (PPP)
• - Understanding of time scale algorithms, clock modeling (Allan deviation), and their integration into navigation filters
• - Experience with inter-satellite link (ISL) ranging, optical navigation, or crosslink-based OD
• - Familiarity with tools such as Orekit, GMAT, or comparable astrodynamics/estimation libraries
