Full Job Description
As a member of a growing PNT team within Amazon Leo, the PNT Estimation and Algorithms Engineer is responsible for designing, implementing, optimizing and monitoring high-precision estimation architectures across terrestrial and space-based networks. You will develop and validate orbit determination, filtering, and sensor fusion algorithms to achieve high precision positioning and timing accuracy using RF and optical inter-satellite link measurements.

Key job responsibilities

Design, implement, and validate orbit determination (OD) and clock estimation algorithms, including Extended Kalman Filters (EKF), Barch Least Square, 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

The base salary range for this position is listed below. Your Amazon package will include sign-on payments and restricted stock units (RSUs). Final compensation will be determined based on factors including experience, qualifications, and location. Amazon also offers comprehensive benefits including health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage), 401(k) matching, paid time off, and parental leave.
