Job Description
In one sentence
As the NonFunctional Testing Lead, you will own the quality and reliability of the products under realworld telecom workloads. You will design, drive, and evolve the full nonfunctional test strategy across performance, scalability, resilience, stability, and resourceefficiency.
What will your job look like?
Team IntroductionThere are 3 products running on premises in Mobile operators data centers and in the cloud, with tens of installations all over the world:
- Product 1: Handling mobile calls, forwarding or rejecting, charging them.
- Product 2: Handling mobile data sessions, doing protocol conversion, session correlation, hiding network topology.
- Product 3: Sending notifications to subscribers via SMS, email, push and other protocol, based on incoming requests, remote servers availability.
All these products are designed for network intensive communication, are based on event driven application server and handle tens of thousands operations per second. Your Responsibilities
