Principal Software Engineer, Manufacturing Test

PDW • Huntsville, AL

76d • Hybrid

About The Position

This role involves leading the design, implementation, deployment, and sustainment of manufacturing test software systems. The engineer will architect scalable software frameworks for automated production test fixtures, diagnostics, telemetry collection, and hardware validation. Key responsibilities include owning software configuration management, deployment pipelines, version control, and release processes. The role also involves developing automation tools, designing and maintaining Linux-based manufacturing systems, and partnering with various engineering teams to integrate software with hardware. Driving root-cause analysis for defects, establishing software validation methodologies, and improving manufacturing throughput are also critical aspects of this position. The engineer will develop tools for data collection and serialization, mentor junior engineers, and contribute to long-term manufacturing software strategy. Collaboration with cross-functional teams and support for deployment and troubleshooting are expected. Additionally, the role involves partnering with product engineering to enhance design-for-manufacturability.
