Senior Software Engineer | Security

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

• Experience with network-oriented security tools such as Wireshark, Tshark, tcpdump, Suricata, Snort, or other packet capture/analysis tools

Preferred Qualifications

• Proficiency in Javascript and Python

• Awareness of current network-based attacks and detection strategies, with a focus on post-exploitation, lateral movement, C2, and exfiltration techniques

• In-depth knowledge of Windows protocols and attack techniques

• Experience with threat hunting, purple teaming, and log/traffic analysis

The salary for this role is 150,000 - 180,000 + bonus + benefits
