Performance Test Engineer, Network Security Cloud

 

Do you want to help make the world safe from cyber attack? 

At Corelight, we believe that the best approach to cybersecurity risk starts with the network.  Attackers can evade endpoint detection, firewalls and many other technologies - but they can’t avoid leaving digital footprints on the networks they traverse.  Built on open-source innovations from Zeek, Suricata and YARA and refined through years of real-world use,  Corelight transforms network footprints from physical, virtual and cloud networks into actionable insights.   Our customers use these insights to speed incident response, proactively hunt for threats and stay in compliance with cybersecurity regulations.   

We are seeking an experienced performance test engineer to validate the performance, reliability and scalability of the Corelight network sensor with a focus on testing in virtual and cloud environments at scale. The sensors can be combined into fleets of sensors to cover the entire network. You’ll harness your skills and experience to isolate the origin of issues from Linux network processing to traffic mix through to detection packages and exporting. Provide dashboards and self-service tooling for collaborators to confirm results in a fully automated fashion. Let the statistical significance of the data direct the prioritization of your work. Feel strongly that the usefulness of our findings directly correlates into how well we can map the symptoms into real work impact.
