  • Experience with CI/CD pipelines and automation frameworks.
  • Solid understanding of networking protocols, system internals.
  • Experience developing or extending tools and existing software.
  • Familiarity with common offensive security tools (Nmap, Metasploit, Cobalt Strike, etc.) and methodologies is a plus.
  • Ability to work independently as well as collaboratively within a security team.
