  • Contribute to the development and maintenance of open-source security tools, incorporating cloud-focused capabilities and threat simulations.

Requirements

  • Familiarity with lateral movement, privilege escalation, and post-compromise techniques in cloud and hybrid environments. 
  • Experience with at least one modern programming or scripting language (Python, Go, etc.) for building tools and automations. 
  • Advantage: Experience contributing to or maintaining open-source security tools. 
  • Advantage: Big data and data analysis skills (e.g., Elasticsearch, pandas, data pipelines) for processing and analyzing large security datasets. 
  • Advantage: Knowledge of detection engineering, telemetry analysis, and log-based threat hunting in cloud environments.
