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.

  • 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.
  • This position is for a senior software engineer. We enjoy training and mentoring each other, but we expect senior members of the team to work through issues independently (even if more slowly) when others are not available.
  • Proficiency with the Haskell programming language is required, including widely-used libraries and styles of functional programming.
  • Understanding of multi-threaded programming for both concurrency and parallelism is required.
  • Understanding of machine-level efficiency issues including high core-count computer systems, memory caching, and NUMA, is a strong benefit.
  • Some ability to read assembly language would be a strong benefit, as would the ability to read "core" output from GHC.
  • Some knowledge of C and would be helpful, as well as the Haskell FFI.
  • Familiarity with Linux systems would be a plus.
  • Familiarity with Nix package management and the Nix language would be a plus.
  • Knowledge of the Rust programming language is not required but would likely be beneficial to future research into parsing infrastructure alternatives.
  • Competitive salary with RSU grant.
  • Comprehensive medical, dental, and vision.
  • 401k with company match.
  • Flexible vacation.
  • Flexible work hours and paternity/maternity leave.
