About The Position

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 Lab Engineer to operate and maintain acceptance‑lab infrastructure, preparing test environments, installing builds, executing standardized test packs, capturing telemetry, and preserving golden configurations to support repeatable and auditable certification workflows. This role ensures all activities follow established tools, safety standards, and documentation practices.
The Senior Lab Engineer will run scripted test cases, perform CIQ and integrity checks, log defects, manage lab equipment, and publish results and artifacts aligned with acceptance criteria, OSS integrations, and NOC handover requirements for beta cycles and commercial launches.
This is a hands‑on technical role within our satellite‑cellular testing ecosystem, requiring precision, discipline, and operational excellence. Success depends on strong attention to detail, strict adherence to procedures, and the ability to work effectively with complex testing infrastructure while upholding high safety and quality standards.

• Execute test packs according to established procedures and acceptance criteria with comprehensive functional and performance coverage
• Run scripted tests in automated and manual environments following standardized procedures and maintaining detailed execution logs
• Capture telemetry and performance data during test execution for accurate collection and analysis of critical system metrics
• Perform CIQ checks to validate system compliance with technical specifications and customer requirements
• Log defects identified during testing with detailed reproduction steps, evidence, and impact assessment for effective resolution
• Publish results and artifacts from test execution with comprehensive documentation of outcomes and certification evidence
• Support repeatable, auditable certification workflows through consistent documentation and compliance with quality standards
• Ensure safety compliance in all lab operations following industry standards and company policies
• Align with acceptance criteria for each test cycle ensuring validation activities meet specified requirements and quality thresholds
• Support OSS hooks and operational support system integration points with properly formatted lab results and data
• Support NOC handover requirements by providing test evidence, configuration documentation, and operational readiness artifacts
• Support beta and launches through targeted testing, validation of configurations, and provision of deployment evidence
