Full-time Mid-Senior Level

Job Overview

Who You’ll Work With

Arista's Network Detection and Response (NDR) platform is a mission-critical security tool for our customers. Its reliability is paramount. We are hiring a senior, founding Customer Reliability Engineer (CRE) to join our team. This role is foundational to the evolution of our customer-facing infrastructure and operational posture.

What You’ll Do

  • Develop and maintain software that parses network traffic for the purpose of extracting key features for threat analysis.
  • Improve the speed, quality, and ease of use of the parser infrastructure.
  • Work with data consumers to define which features to extract from network traffic.
  • Discuss general requirements with others and help to define specifications to satisfy those requirements.  The engineer is expected to lead on individual tasks, though with review and feedback from others.
  • Where the situation warrants it, make suggestions for more general improvements that involve multiple product components, not just the traffic parser.
