Jobbeschreibung

Описание

Refractal is an AI security company building the infrastructure organisations need to defend against autonomous AI threats. 2026 has shown that generally capable intelligence is here. The challenge now is modernising security to stop AI-enabled threats, whether they come from internal agents going rogue or from attackers using AI to become more dangerous.

Задачи

Translate detection and investigation workflows into product requirements, helping engineers understand what security teams need and why. Use your experience with detection rules and SIEMs such as Splunk and Datadog to guide product design and integration priorities. Build realistic examples and test cases that capture attacker behaviour, benign activity and common sources of false positives. Evaluate product outputs for detection quality, useful context and the effort required for an analyst to reach a decision. Work with customers and colleagues to identify gaps, prioritise improvements and check that changes address practical security needs.

Требования
  • Hands-on experience writing and tuning detection rules, with examples of how you assessed whether they worked.
  • Practical experience using SIEM platforms, including Splunk or Datadog, to query security data and investigate activity.
  • Experience in detection and response, with a clear understanding of analyst workflows, false positives and gaps in security telemetry.
  • The ability to explain security problems to software engineers and translate your experience into requirements and test cases.
  • An interest in building products and a willingness to challenge assumptions using evidence from practical security work.
  • Будет плюсом: Experience contributing to a security product or working closely with software and research engineers; Scripting skills for preparing data, prototyping ideas or creating repeatable security tests; An interest in how AI changes attacker behaviour and the security of autonomous agents
