• Design network topologies replicating various data centre and telecom network segments reflecting the network designs used by our customers
• Reviewing and improving test plans from the network engineer's standpoint
• Support functional and regression testing of the network OS, in virtual environments, on actual hardware or in hybrid networks
• Execute QA testing of the NOS according to implemented and newly defined test plans to validate functionality post bugfix implementation and prior to new version release
• Design and implement CI/CD pipelines for QA purposes aimed at continuous testing of the NOS
• Fix deficiencies (bugs) in the QA simulation orchestrator, CI pipelines and QA scripts
• Work with the software development team in order to implement test scenarios as new features are added or OS functionality is updated
• Investigate and reproduce bugs reported by the field team or developers, perform root cause analysis and support the development team as they work on bugfixes
