What does a performance test engineer do?

A performance test engineer is responsible for conducting performance testing to ensure system capacity, reliability, and scalability. Typical duties that you will perform include working closely with the testing team in developing performance test cases and plans, analyzing test results, and handling bug fixes in collaboration with development teams. Additionally, you will be responsible for evaluating the root causes of performance problems and resolve them. You will also be responsible for developing automated test scenarios for performance testing.

What does a functional tester do?

A functional tester's main responsibility is to validate the behavior of an application and analyzed the requirements of the clients. They are skilled in Java and database design for software development. The tasks they do are complex, including scanning IDs of the receiver and serial numbers on each unit, testing the units to make sure they work properly, and checking for any defects and damages. They are also trained in using numerical codes for passing or failing each unit and writing serial numbers on the production tracker.
