AST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today’s five billion mobile subscribers and finally bring broadband to the billions who remain unconnected. Position Overview The System \ SW Test team at AST SpaceMobile is responsible for verifying and validating the embedded software that runs aboard all spacecraft in the AST fleet. We are seeking a junior Test Software Engineer with AOCS (Attitude ability to read and follow flight software code with guidance. Foundational understanding of control systems theory (e. g. closed-loop dynamics, PID controllers, or state-space concepts). Introductory knowledge of orbital mechanics (e. g. Keplerian orbits, reference frames, coordinate transformations) Awareness of attitude representations such as Euler angles, rotation matrices, or quaternions, at a conceptual level. Analytical mindset with attention to detail and a willingness to learn in a fast-moving engineering environment. Communicates clearly in written and spoken English; comfortable asking questions and collaborating with remote teams. Preferred Qualifications: Experience writing automated test frameworks or continuous integration pipelines for embedded or real-time software. Familiarity with spacecraft sensors and actuators for attitude determination and control systems including star trackers, IMUs, reaction wheels, magnetorquers, or thrusters. Experience with hardware-in-the-loop (HIL) or software-in-the-loop (SIL) test environments. Exposure to spacecraft telemetry tools, ground software, or mission operations environments. Knowledge of estimation theory Experience using Jira or similar issue-tracking and project-management tools. Familiarity with version co
