About the role

Senior Backend Engineer on the Precision Defense team helping to move customers from reactive security toward proactive, evidence-based defense across Rapid Response, Tripwires/Deception, Security Controls/EDR, and Autonomous Defense.

Responsibilities

  • Build and maintain backend APIs, ETL pipelines, and data processing systems that power Rapid Response, Tripwires, EDR effectiveness, and Autonomous Defense workflows.
  • Design and implement GraphQL APIs to facilitate data interactions across product components.
  • Develop event-driven services and distributed systems that support reliable, scalable security automation.
  • Collaborate with frontend engineers, attack engineers, and product managers to deliver customer-facing features that communicate security findings clearly and actionably.
  • Contribute to production reliability: monitoring, alerting, incident response, and debugging across ETL, deployment, and data-propagation workflows.
  • Support safe, explainable, and reversible security automation — understanding that incorrect behavior in this domain can mean missed detections, noisy alerts, or false confidence for customers.

Qualifications

  • Bachelor's Degree in Computer Science, Computer Engineering, or related field.
  • 7+ years of professional software engineering experience using modern object-oriented or functional languages (Python, Java, Go, Scala, C++, TypeScript, etc.).
