We are looking for an engineer who builds data pipelines and writes code to understand a live satellite network. Amazon Leo is an initiative to launch a constellation of Low Earth Orbit satellites that will provide low-latency, high-speed broadband connectivity to unserved and underserved communities around the world. You will monitor Amazon Leo's live satellite network against what our simulations predict, and use what you find to improve the performance our customers receive. You will help build and run an automated pipeline that compares real-time system and network data with simulation predictions, finds where performance falls short, and helps drive each problem to resolution with the many teams involved. A problem can sit anywhere in the system: satellites and their optical inter-satellite links, gateways, user terminals, the satellite telemetry, tracking and command (TT&C) link, and the software that connects them.
You will join a new, interdisciplinary team that covers software and data pipelines, radio frequency (RF) and link performance, artificial intelligence and machine learning (AI/ML) automation, networking, systems integration and test, and production operations and troubleshooting, and that works closely with the modeling and simulation, hardware, software and operations teams across Amazon Leo.
Export Control Requirement
Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident that is a current Green Card holder, or lawfully admitted into the U.S. as a refugee or granted asylum.
Key job responsibilities
Data pipeline and performance framework
- Build, maintain and use the team's automated pipeline that brings live system and network data, simulation predictions and test measurements together
- Design how the data is stored, queried and kept at scale, so that the pipeline runs reliably and unattended across the whole network
- Write the code that joins sources logged at different rates and times, and keep each record's context with it so that later analysis can explain it
- Integrate simulations and models developed by other teams into the team's framework, and co-develop each tool's automation interface with the team that owns it
- Compare live performance with simulation predictions within tolerances that reflect what each prediction means, and report when the model, not the network, looks wrong
Rapid detection of changes that affect customers
- Build AI, machine learning and automation steps into the pipeline to rapidly detect, group and triage changes that affect customers, and check their conclusions against independent evidence
- Develop statistical change-detection methods that flag when performance moves away from the network's own history
- Turn large telemetry data sets into trends, visualizations and findings the team and its partners can act on
Troubleshooting and resolution
- Help trace performance problems to their root causes across RF, software, hardware and networking, by comparing affected and unaffected terminals, satellites and gateways
- Confirm a cause with an independent measurement, or reproduce the fault in simulation or test
- Hand each cause, with its evidence, to the team that owns the fix, and verify after the fix that customers see the improvement
Documentation and collaboration
- Build up a database of anomaly signatures, so that each investigation builds on earlier ones and known problems are recognized quickly
- Work with the simulation, test, satellite, gateway, terminal and software teams across our organization to get the data and evidence each investigation needs
A day in the life
About the team
We are a new team inside Amazon Leo’s communication systems organization. We turn live network data into clear answers about the performance customers receive, and then work with subject matter experts to improve the customers’ experience. Amazon Leo’s network serves consumers, businesses and government organizations; within Amazon Leo, the team supports the engineering and operations teams that need reliable evidence of how the network performs.
Basic qualifications
- Bachelor's degree in Electrical Engineering, Computer Engineering, Systems Engineering, or related fields
- 5+ years of experience in data engineering, software engineering or data analysis
- Experience building automated data pipelines that join and process large data sets, using SQL and Python or similar
- Experience analyzing telemetry, log or field data to find the root cause of a problem
- Experience writing software, for example in Python, C++ or MATLAB, with version control and testing, to automate analysis or test
Preferred qualifications
- Master’s degree in electrical engineering, statistics or a related field
- Experience operating or supporting a production network or satellite system
- Experience with RF, satellite or wireless communication systems: link budgets, link adaptation, or link and network performance
- Experience building AI/ML steps into automated data processing flows, with checks on their output
- Experience in satellite, wireless or network systems engineering, integration and test, or operations
- Experience with data lakes and query engines at scale, for example Athena, Spark or Redshift
