QA Automation Engineer

In this role, you will design and implement automated tests for the Network Visibility MobileStack products, to ensure that Keysight delivers high quality products and solutions to their customers. MobileStack, along with the other Keysight Network Visibility products, provide the ability for our customers to tap, aggregate, filter, sample, as well as perform many other functions on their network traffic for monitoring and analysis.

Keysight’s network packet broker provides multiple applications, such as:

• MobileStack – monitoring of customer traffic from a mobile user/session perspective (e.g.GTP, SIP/RTP)
• AppStack – monitoring of customer traffic from an application perspective (i.e. L4-L7)
• SecureStack – providing secure encryption/decryption for TLS1.3 (Active SSL)
• TradeVision – stock trading monitoring and analysis tool
• PacketStack – standard packet broker features such as aggregation, deduplication, masking, etc.
• NetStack – port tagging and VLAN stripping

Our MobileStack products track mobile users and sessions, sending the associated control and user plane data to specific network monitoring tools (i.e. probes) for analysis. In addition, they load balance across probes and provide sampling, filtering and VIP whitelisting functionalities. This allows our customers to manage their probe bandwidth by looking at a subset of the overall network traffic, in addition to being able to troubleshoot specific quality of service issues. As network traffic continues to increase each year, our customers need solutions to monitor their network traffic more efficiently and cost effectively.

This position is an opportunity to contribute to our product and team, as we continue to evolve our MobileStack product to meet the demands of 5G core network and network virtualization.
