Senior Software Engineer | Security

ExtraHop is reinventing Network Detection and Response (NDR) to help enterprises and organizations 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. 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. It provides 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. We’re doing it with creativity, intellectual curiosity, and deep critical thinking.

Key Responsibilities

• Detection Engineering:
  • Develop network threat detectors by leveraging rule-based and ML-based detection strategies
  • Reproduce attacks in a lab environment using live tools and recorded PCAP traffic, and perform threat hunts on aggregated log data, in order to identify malicious behaviors and develop techniques to detect them
  • Collaborate with Threat Research and Data Science teams to gain insight on attacker techniques and take advantage of the latest machine learning models to detect attacker behavior
  • Work with infrastructure teams to help develop and improve tools that Detection Engineering and Threat Research teams use in developing and testing detections
• Mentorship:
  • Mentor and coach other Security Engineers regarding detector development and network threats
  • Actively participate in code review to ensure quality and uplevel other engineers

Required Qualifications

• Excellent engineering chops
• 7+ years of experience in software engineering
• Solid knowledge of Javascript and Python
• In-depth knowledge of networking fundamentals, including the OSI model and excellent working knowledge of the key protocols from Layer 2 through Layer 7
• Experience developing solutions using cloud-native technologies
• Self-starter with a strong problem-solving track record and ability to grow and learn
• Excellent teammate and collaborator who can iterate on problems quickly
• Proficient at communication in both spoken and written forms, including documentation

Preferred Qualifications

• Experience working with network packet-level data using tools like Wireshark, tshark, tcpdump, tcprewrite, and Scapy to directly interact with this data
• Knowledge of cloud and on-premise cybersecurity threat models - attacker behavior, tools, techniques, and practices. Ability to translate this knowledge into user-facing threat detections

The salary for this role is between $150,000 - $180,000 per year + bonus.
