USA, WA, Redmond - 143,700.00 - 194,400.00 USD annually
The Command and Data Handling (CDH) team in Amazon LEO provides the foundational telemetry infrastructure that enables the rest of the Kuiper organization to fly and sustain thousands of satellites in low earth orbit (LEO). Every flight control group, hardware owner, and mission operator depends on CDH-delivered telemetry to observe, diagnose, and act on satellite and ground appliance health.

We build and operate the systems that ingest, decode, route, and deliver telemetry from spacecraft and ground appliances to the engineers and automated systems that keep the constellation healthy. Our software spans embedded agents running on resource-constrained appliances through high-throughput cloud services, and it has to be correct, observable, and resilient, because the rest of Kuiper can't operate on data it can't trust.

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
As an Software Engineer on CDH, you will own the design, implementation, and operation of telemetry services and agents end to end. You'll take ambiguous problems — "we need to scale ingestion to N more satellites," "operators need this signal sooner and more reliably" — and turn them into designs, code, and running systems. You'll write production C++ and/or other systems/cloud code, drive technical decisions within your area, and raise the operational bar for software that thousands of downstream users depend on.

This is a hands-on building role with real ownership. You will be expected to deliver complex features independently, decompose large efforts for yourself and others, and mentor more junior engineers through design and code review.

About the team
We support each other. This is a high-stakes domain, and nobody succeeds alone. We share context generously, mentor as a default, and keep a low ego about asking for and offering help. When something breaks, we swarm the problem instead of pointing fingers, the goal is to fix it and learn, not assign blame. New engineers are paired with people who'll help them ramp, and senior engineers treat growing the team as part of the job. We also have a snack bar stocked with the snacks and beverages people actually want.
