At ExtraHop, we’re on a mission to protect and empower the connected enterprise. We reveal what is happening in the very infrastructure that sustains businesses, lives, and communities, and ensure the integrity of networks, data, systems, and processes. Organizations rely on ExtraHop to provide visibility into the cyber threats, vulnerabilities, and network performance issues that evade their existing security and IT tools. With this insight, organizations can investigate smarter, stop threats faster, and keep operations running.

Our mission is fueled by a profound social and moral responsibility to be the best at what we do, ensuring a secure world where everyone can thrive. If this sounds like a place you’d like to spend the next chapter of your career, we’d love to hear from you.

Position Summary

An ideal candidate will have strong software engineering, networking, and cybersecurity fundamentals. This position works with security researchers and developers, developing systems to make them more efficient and effective. You'll deliver impactful solutions that empower research and development, as well as working directly with network data to emulate adversary behavior.

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.

Key Responsibilities

Support Threat Research and Detection Engineering teams by providing tools and automation to accelerate Research & Development.
Develop and support internal systems, including:
Software deployment pipelines supporting continuous delivery
Pipelines for ingestion of new network identifiers to enable fingerprinting of device, software, and cloud services
Threat Intelligence acquisition and sharing
On-demand threat research labs using modern Infrastructure-as-Code and Cloud-based technologies
Continuous Testing and Validation pipelines
Work with a collaborative, dedicated and seasoned team of engineers
Actively participate in code review to ensure quality and uplevel other engineers

Required Qualifications

Bachelor’s degree in Computer Science, Computer Engineering, or a related technical field, or equivalent practical experience.
5+ years of experience in software engineering
Excellent engineering chops
Solid knowledge of Python
Experience developing and deploying code for enterprise software applications with emphasis on code quality and maintainability
In-depth knowledge of networking fundamentals, including the OSI model and excellent working knowledge of the key protocols from Layer 2 through Layer 7
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 tshark, tcpdump, tcprewrite, and Scapy to directly interact with this data.
Strong understanding of TCP/IP and Layer 7 protocols

Compensation & Benefits: The salary range for this role is $150,000 – $163,000 per year, plus eligibility for an annual performance-based discretionary bonus and stock option grants. We offer a comprehensive benefits package including medical, dental, and vision coverage (effective Day 1), a 401(k) with employer match, flexible PTO, parental leave, and more.
