Senior Software Engineer | Security

ExtraHop

8d • Hybrid

About The Position

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 ExtraHop. We're on a mission to provide security teams with the intelligence they need to confront and stop advanced threats like supply chain attacks, zero day exploits, and ransomware attacks. Cyber attackers still have the advantage. We’re taking it back with creativity, intellectual curiosity, and a sense of humor. Are you ready to help us reclaim the upper hand
We are seeking a highly skilled and motivated Senior Software Engineer | Security with a strong software and detection engineering background to join our Detection Engineering (DE) team and help expand ExtraHop’s industry leading detection coverage.
An ideal candidate will have strong software engineering, networking, and cybersecurity fundamentals. This position works closely with security researchers and data scientists to develop cutting edge network threat detections that leverage rule-based network observations as well as ML-powered anomaly detections.
As a Senior Software Engineer | Security, you will be working as part of a team dedicated to delivering industry leading detection capabilities. You will be expected to work with a high level of autonomy, to mentor other team members, and to demonstrate a high level of ownership of your areas of responsibility.
ExtraHop offers an exciting, high-energy, and versatile environment in which people are encouraged and supported to collaborate on industry-leading technology and create a world-class engineering team while they develop and enrich their individual growth. And we're doing it with creativity, intellectual curiosity, and deep critical thinking.
ExtraHop R&D supports fully-flexible work options that include full-time onsite, hybrid, and fully remote working arrangements. Except for a few roles that require physical access, we believe in supporting you in making the choice that works best for you and makes the team successful.
