Software Quality Engineer III

Company: ExtraHop
Location: San Diego
Posted on: January 21, 2026

Job Description:

ExtraHop is reinventing Network Detection and Response (NDR) to help enterprises and organziations stay ahead of emerging threats with unmatched network visibility, context, and control. Today’s attackers bypass traditional security defenses through identity-based entry, move invisibly across cloud, on-premise, and data center networks using encryption and trusted applications, and exploit and exit whenever they want. But all of that movement is visible on the network if you can see it. By combining the power of NDR with Network Performance Management (NPM), Intrusion Detection Systems (IDS), and forensics in a single, integrated platform, ExtraHop can decrypt and unlock complete packet-level data at wire speed, analyze and correlate it across all your networks, applications, devices, and users with cloud-scale machine learning, and provide a single interface to the SOC to detect, investigate, and remediate modern cyber risks in real time. Position Summary We are looking for a Software Quality Engineer III with a passion for software quality and strong understanding of the software development life cycle (SDLC) in an agile environment. The ideal candidate will have a strong testing ability , a detail-oriented mindset, and the ability to collaborate across teams to ensure our products meet the highest standards.
