Position Overview
The Principal Electro-Optics Test Software Development Engineer is an established and experienced member of the new products development/introduction team bridging the space between prototype concepts and final delivery of electro-optic products from R&D to manufacturing. The primary job activity provides automated test set software, instrumentation, and test methods to support certification testing of SubCom’s novel undersea electro-optic network elements. The role involves high level planning, platforming, and innovation across multiple products, production test sets, as well as the development of new electro-optic test sets and test methods. The role reports to the Director of Certification Test Engineering
Responsibilities
• Develop software architectures, automated test systems, procedures, and executable code to support certification testing of advanced electro-optic products and new product introduction initiatives.
• Design and implement data acquisition, instrumentation control, and test automation solutions to improve test efficiency, accuracy, and repeatability.
• Partner with R&D engineers throughout the product development lifecycle to define, develop, and validate product test strategies and certification methods.
• Lead the transfer of new products, test software, and qualification processes from development into manufacturing, ensuring production readiness and scalability.
• Collaborate with Production Engineers and Equipment Designers to integrate, deploy, and optimize manufacturing test platforms and processes.
• Provide ongoing support for production testing operations, including software maintenance, troubleshooting, and resolution of product and test equipment issues.
• Drive continuous improvement of test software development processes, including requirements management, software architecture reviews, coding standards, and formal design/code review practices.
• Analyze complex technical problems, identify root causes, and implement corrective actions to maintain product quality, reliability, and manufacturing throughput.
• Serve as a technical leader and subject matter expert for automated test systems, influencing engineering best practices across multiple programs and product lines.
• Mentor and provide technical guidance to engineers and technicians, supporting skill development, knowledge sharing, and successful project execution.
