About The Position

Barrios Technology is seeking a Joint Station LAN Lab Test Engineer to support the Boeing Engineering Technical Services contract in Houston, Texas. The role tests and validates network hardware, connected devices, and Ethernet communications to help ensure reliable network performance for systems supporting human spaceflight. The position is based in the Joint Station LAN Laboratory at NASA’s Sonny Carter Training Facility and supports verification of components, hardware, software, and user payload devices for connection to the International Space Station Joint Station LAN. The engineer works with network engineers, software teams, hardware specialists, NASA customers, and other stakeholders to assess test requirements, configure laboratory equipment, execute test procedures, analyze network performance, and troubleshoot technical issues. The work includes documenting test results, supporting verification and validation, helping users understand LAN architecture and testing processes, and maintaining a safe and organized laboratory environment. Work is generally in an office environment but may involve indoor or outdoor tasks, commuting, and travel to other installations as needed. The role may require schedule adjustments to support peak periods and surge requirements. Applicants must be U.S. citizens and successfully complete a U.S. government background investigation; eligibility requirements for access to classified information may apply. A post-offer, pre-employment drug test is a condition of employment.
