Automate Testing: Develop automated testing frameworks and tools to streamline validation processes.
Analyze Results: Document and analyze test results, providing detailed reports and recommendations for system improvements.
Support Development: Ensure a “design for testing” focus during system development and integration.

What You Bring

Bachelor’s degree in Engineering (Systems, Mechanical, Electrical, Software, Ocean), Computer Science, Physics, or Math.
2+ years of hands-on testing, integration, validation, and verification experience with software and integrated electro-mechanical systems including developing test procedures
