  • Perform structured security audits and drive remediation of risks
  • Monitor Substack’s vulnerability reporting program

  • Collaborate with IT team on security operations and internal security


  • 4+ years of relevant experience with security engineering or security architecture
  • Domain knowledge across cybersecurity disciplines, with a focus on application and cloud security
  • Independent and autonomous. We’re too small to micromanage and expect that every person at the company owns their work and can be a leader.
  • Hold yourself and others to a high standard when working on production systems.
  • Enjoy collaboration with a diverse group of stakeholders while bringing your own unique experience and background to the team.

Nice to have
