About Test Engineering

The Nokia Deepfield Test Engineering (TestEng) team is a global team of technical experts that help our software development teams validate product requirements and address defects before product release. Test Engineers are integrated in development teams and actively participate in all aspects of the SDLC. We collaborate with product and project teams to create test plans, develop tests, and execute against code changes as the software is created to ensure business requirements and expectations are met. We believe that quality is not the responsibility of a single person and is a core value that needs to be instilled in the entire organization. We are advocates for quality without sacrificing velocity, using creative solutions to ensure functionality.
