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 & Orbit Control System) domain knowledge to join our India-based System SW Testing team and contribute to the verification and validation of flight software that implements attitude and orbit control functions.

In this role, you will develop and maintain automated FSW (Flight Software) test frameworks and your controls domain background will allow you to write meaningful tests,



interpret results in physical terms, and work effectively with both the FSW and AOCS engineering teams.

Key Responsibilities
- Design, develop, and maintain automated test scripts and frameworks in Python and MATLAB
- Implement and execute unit, integration, and software-in-the-loop (SIL) tests for AOCS algorithms including attitude control laws, momentum management, and thruster firing logic
- Review and debug C++ flight software modules to identify and trace defects revealed by test execution or on-orbit telemetry analysis related to attitude sensors
- Maintain and improve test infrastructure, including simulation environments, truth models, and automated reporting pipelines.
- Document test results, anomaly reports, and lessons learned in Jira and internal knowledge-management systems.
- Serve as a bridge between the FSW and AOCS teams, translating AOCS domain requirements into testable
