Phased Array Software Dev Engineer, Project Kuiper Antennas

Software Development Engineer

Project Kuiper 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. Innovation is part of our DNA. The Antenna team is responsible for the design, performance, and calibration of all Kuiper antennas across payload and customer terminals. We own the end-to-end performance of the RF systems that bring Kuiper to life.

We are looking for a Software Development Engineer to help architect and deliver scalable software systems that test, validate, and optimize Kuiper's phased array antennas and RF performance at scale. This engineer will work at the intersection of hardware, embedded systems, and cloud-scale software, helping prove out the next generation of antennas that will ship to millions of customers around the world. If you've ever wanted to see your software directly drive the performance of real hardware in orbit or in customers' homes this is the team where that happens.

Key job responsibilities:

• Architect and implement software frameworks to automate performance testing and calibration of Kuiper's phased array antenna systems.
• Develop scalable, production-quality software (C++, Rust, and AWS-based solutions) that validates system performance from concept to manufacturing.
• Build automation to test system-level functionality, link budgets, and RF performance metrics.
• Partner with hardware and system development teams to baseline and harden software derived from early prototype Python code.
• Enable data-driven performance insights through automated test execution, collection, and analysis pipelines.
• Collaborate with manufacturing and calibration teams to ensure that every Kuiper antenna shipped meets performance standards.
• Define and execute software release processes, CI/CD, and quality verification.
• Work hands-on with hardware test equipment, antennas, and integrated systems.
• Deliver clear documentation and user-focused software for engineering and manufacturing teams.

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.

A day in the life:

You will design and implement the software that validates the performance of Kuiper's antennas from lab test benches to fully integrated customer terminals. Your tools and systems will prove out the performance of one of the most advanced communication systems ever built. You'll collaborate with RF and systems engineers, see your code run on live hardware, and make daily decisions that directly affect the readiness of Kuiper's payload and terminal products. The software you build will enable critical data collection, system analysis, and calibration pipelines that ensure Kuiper hardware performs flawlessly on Earth and in orbit.

About the team:

This Software Development Engineer will join the Antenna and System Performance team, part of Kuiper's larger Antenna and RF Engineering organization. Our team owns the full performance lifecycle of Kuiper's antenna systems from early concept testing and calibration to final product release. We operate at the intersection of RF hardware, software automation, and large-scale system integration. You'll work closely with antenna, DSP, and system development engineers, contributing to test frameworks, manufacturing support, and performance validation. We leverage AWS tools and scalable software architectures to accelerate development, automate validation, and deliver reliable test systems used across the entire Kuiper organization. If you want to work on real hardware, influence product performance, and see your work scale to millions of users worldwide this is the place to do it.
