Conventional Test Facility
Amentum is supporting an advanced U.S. Navy test facility project, an effort that began over a decade ago and will continue for years to come. This large-scale initiative spans multiple engineering disciplines (process, mechanical, controls, software, structural) and requires hands-on work with hardware.
The software team drives all data acquisition and control room functionality. This includes reading sensor values through NI hardware (cRIO and PXI), streaming data to Redis for real-time GUIs, and storing data in Kafka for long-term analysis. Control room tasks involve building operator interfaces for monitoring, recording, and triggering test sequences, integrating site cameras, and communicating with PLCs to control moving components.
About 95% of the code is written in NI LabVIEW, training will be provided, so no prior experience is required. As a team member, you'll contribute to both data acquisition and control room development, gaining hands-on experience with LabVIEW, Redis, Kafka, MSSQL, Git, and collaborative software engineering practices.
