Senior Systems Validation Engineer
AST SpaceMobile
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
We are seeking a Senior Systems Validation Engineer to be a key contributor to the validation of hardware and software features for our space-based RF and communications systems. This role ensures that hardware and software perform reliably in controlled environments such as labs and anechoic chambers, as well as during over-the-air (OTA) satellite testing. The ideal candidate will execute test plans, perform hands-on validations, and collaborate with remote teams to verify system performance against mission-critical requirements. This role is hybrid 3 days on site at Lanham.MD location / 2 days virtual. Within 6 to 9 months position will relocate to Tysons Corner, VA.
Key Responsibilities
- Develop and execute comprehensive validation plans for HW and SW features, including signal processing, beamforming, and communications protocols in lab, anechoic chamber, and OTA satellite environments.
- Execute hands-on testing and troubleshooting to verify system performance, integration, and compliance with requirements for phased array, RF, and SATCOM systems.
- Collaborate with remote engineering teams to review validation deliverables, identify issues, and provide technical feedback to ensure alignment with defense and commercial goals.
- Conduct OTA validations from satellites, analyzing performance metrics such as link budgets, interference, and signal quality in real-world scenarios.
- Contribute to system verification and validation, including proof-of-concept evaluations and customer acceptance testing.
- Translate validation results into clear reports and presentations for stakeholders and cross-functional teams.
- Mentor junior engineers on validation methodologies, test procedures, and tools for HW/SW integration.
- Support proposal pursuits and RFI/RFP responses related to validation for defense programs.
Qualifications
