Senior Lab Engineer

Senior Lab Engineer Lanham, Maryland, United StatesAST 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 OverviewWe 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 adnce to procedures, and the ability to work effectively with complex testing infrastructure while upholding high safety and quality standards.
