Software Development Engineer, Amazon Leo Antenna Development

Amazon Leo is building a constellation of 3,236 satellites to deliver broadband from space. Our direct-to-device (D2D) program takes it further, connecting everyday phones and devices directly to satellites. Come build it.

We"re looking for a software engineer who wants to ship code to orbit. You"ll own the pipelines that build, sign, and deploy software from the ground to a constellation of satellites. This isn"t typical CI/CD. You"ll work with hardware-in-the-loop test environments, factory calibration stations, and embedded Linux targets. You"ll build simulation frameworks and cloud test infrastructure alongside 5G, RF, and embedded software engineers. The engineering challenge: scale software delivery to thousands of satellites, reliably, with no room for error. You don"t need satellite experience to start, but you"ll gain deep exposure to embedded systems, hardware, and space-grade engineering.

We"re a small, growing team inside Amazon Leo. We own the software layer for the satellite antenna payload, the services and infrastructure that make beam-forming, calibration, and hardware control actually work. You"ll work alongside embedded software engineers, SDEs, RF engineers, and hardware teams, and you"ll have real ownership from day one. The team is early enough that your decisions will shape how we build and test for years. If you want high-impact work on one of Amazon"s most ambitious technical programs, come join us.

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

Do you want to put code in space? Have you wanted an opportunity to develop the core wireless and networking for an advanced global telecom service spanning both space and terrestrial networks? Have you wondered what it takes to solve a multi-dimentional resource allocation problem at global scale?

• Own the software delivery path from ground to orbit, pipelines that build, sign, and deploy to satellites
• Build factory test station software that calibrates phased-array antennas before they leave the floor
• Create simulation environments that let the team catch bugs before hardware exists
• Design cloud infrastructure that orchestrates tests across hardware-in-the-loop environments
• Shorten the loop between "code written" and "validated on real hardware"
• Work directly with 5G, RF, and embedded software engineers to understand what they need and build it

About the team

At Amazon Leo, we believe that our differences makes us stronger. We are committed to Amazon's culture of inclusion ingrained in our Leadership Principles, which encourages team members to seek diverse perspectives, learn and be curious, and earn trust. We want to foster a culture of collaboration, delivering results and work/life balance.
