- Defining testing processes and selecting appropriate tooling
- Analysing metrics to verify system performance and ensure scalability
- Documenting guidelines (e.g., Software Delivery Plan) for successful project completion

You’ll balance mentorship with hands-on execution while driving quality assurance for a high-impact national security application.

- Implement continuous integration/delivery (CI/CD) practices where applicable
- Maintain test management tools, report discrepancies, and drive regression testing
- Ensure consistent, reproducible test results with robust documentation
- Act as a bridge between developers, testers, and stakeholders (e.g., project managers)
