About the role

  • NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises.
  • As Horizon3 has grown in both customer count and customer size, pentest execution and data processing times scaled as well.

Responsibilities

  • This work combines platform engineering to build the infrastructure foundation with cybersecurity domain understanding to translate years of batch-centric business logic into real-time processing.
  • Lead and grow a team of backend and platform engineers migrating post-op processing from a batch system to a real-time, event-driven architecture.
  • Partner with Product, Attack Engineering, and adjacent Platform teams to sequence the rework so customer value ships continuously rather than as one big-bang cutover.
  • Help translate existing batch-era logic (finding enrichment, attack path analysis, reporting) into streaming-friendly designs without regressing fidelity.
  • Establish healthy team practices: design reviews, technical writing, clear API contracts with neighboring teams, and durable decision records.
  • Solid fundamentals in backend and distributed systems: data modeling, API design, queues/streams, and the tradeoffs between batch and streaming.
  • We believe that diverse perspectives drive innovation and strengthen our ability to create cutting-edge cybersecurity solutions.
