  • Integrate enterprise telemetry, marketplace activity, physical security events, OSINT, support interactions, and external signals.
  • Develop automation, agents, and investigative tooling that improve detection quality and reduce repetitive work.
  • Own the detection lifecycle from hypothesis and data validation through deployment, tuning, measurement, and retirement.
  • Conduct technical triage and investigations by correlating signals, assessing confidence and scope, and supporting response decisions.

  • Production experience building and operating detection-as-code pipelines with source control, testing, review, deployment, and monitoring.
  • Track record of developing automation that improves detection accuracy, response speed, or investigative quality.
  • Experience building and evaluating agents or LLM-backed tools for detection or investigation use cases.
  • Strong investigative judgment and ability to turn incomplete information into testable hypotheses.
  • Experience working with diverse structured and unstructured security or behavioral datasets and assessing data quality.
  • Knowledge of telemetry such as marketplace activity, physical access, alarms, video, OSINT, or support interactions.
  • Strong knowledge of cloud-based and distributed systems, including troubleshooting queries, code, pipelines, and source systems.
  • Mastery of SQL or SIEM query languages such as SPL or KQL, plus proficiency in Python, Go, or another relevant language.
  • Experience with MITRE ATT&CK, D3FEND, or similar frameworks; Snowflake, Cortex, or Google SecOps experience preferred.
  • Excellent communication, stakeholder management, discretion with sensitive information, and mentoring skills.
  • Bachelor’s degree or equivalent practical experience.

  • 401(k) plan with employer matching.
