• Establish meaningful automation and quality metrics and use them to identify opportunities for improvement. \n

• Identify, reproduce, document, and assist in troubleshooting software defects. \n

• Provide developers with clear reproduction steps, logs, traces, and other diagnostic information when investigating defects. \n

• Work with Engineering to improve application testability, logging, diagnostics, and environment reliability. \n

• Contribute to the continuous improvement of QA processes, tools, methodologies, and release practices. \n

Global Caption is a growing company, and this role will evolve along with our products and technology. The responsibilities described above are not intended to be an exhaustive or static list.

\n

As our products, technology stack, automation capabilities, and business needs evolve, the Senior SDET may take on new testing requirements, technologies, platforms, and quality initiatives. Responsibilities, priorities, and performance goals may be updated or expanded over time.

Why This Role Matters\n

Global Caption is not simply launching new services-we are building the technology and quality foundation of a company focused on expanding communication accessibility.

\n

As one of the senior contributors to our quality engineering practice, you will have the opportunity to establish how automated testing is designed, implemented, and integrated into our software development lifecycle.

\n

Your work will directly influence the reliability of our products, the speed and confidence with which we can release new capabilities, and our ability to scale our technology as the company grows.

\n

This is an opportunity to do more than maintain an existing automation suite. You will help build the quality engineering foundation that our products and development teams will rely on as we grow.
