We9re looking for a software engineer who wants to ship code to orbit. You9ll own the pipelines that build, sign, and deploy software from the ground to a constellation of satellites. This isn9t typical CI/CD. You9ll work with hardware-in-the-loop test environments, factory calibration stations, and embedded Linux targets. You9ll 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 don9t need satellite experience to start, but you9ll gain deep exposure to embedded systems, hardware, and space-grade engineering. We9re 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. You9ll work alongside embedded software engineers, SDEs, RF engineers, and hardware teams, and you9ll 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 Amazon9s 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 BASIC QUALIFICATIONS - 3+ years of non-internship professional software development experience - 3+ years of non-internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience - 3+ years of software development engineer or related occupational experience - 3+ years of designing and developing large-scale, multi-tiered, multi-threaded, embedded or distributed software applications, tools, systems, and services using: C#, C++, Java, or Perl experience - 3+ years of Object Oriented Design experience - Bachelor9s degree or foreign equivalent in Computer Science, Engineering, Mathematics, or a related field - Experience programming with at least one software programming language PREFERRED QUALIFICATIONS - 3+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience - Bachelor9s degree in computer science or equivalent - Experience building test automation frameworks and tools - Experience with Linux operating system, embedded systems, consumer devices, or mobile apps - Experience scripting in one or more language (e.g. Bash, Python, Perl, Ruby), or experience working with device technologies under development, familiarity with flashing firmware, basic device debugging and familiarity with reading/pulling device logs - Experience with AWS Services including EC2, Lambda, S3, DynamoDB, SQS
