About the role

  • This role reports to the CTO and has a direct line into every part of the engineering org.
  • You'll be hands-on with modern AI-native security tooling - we use Claude Security and Claude Code as force multipliers for internal pentesting, code review, and remediation.
  • SIEM & SecOps Dashboard: Stand up and operate our SIEM.

Responsibilities

  • Build out the SecOps dashboard that gives engineering, compliance, and leadership a real-time picture of our security posture - alerts, anomalies, auth events, infrastructure changes, and audit-ready evidence in one place.
  • Document findings, drive remediation, and measure mean-time-to-fix.
  • Own the vulnerability lifecycle end-to-end.
  • Build the automation that keeps packages patched without breaking production - including Dependabot tuning, lockfile hygiene, and gated auto-merge for low-risk upgrades.
  • We're hiring for a Security Engineer to own the day-to-day defensive and offensive security posture of Coinflow.
  • You'll build the SecOps backbone, hunt for weaknesses in our own stack before anyone else does, and partner with engineering to keep our SDLC fast and secure.
  • Vulnerability & Dependency Management: Own the vulnerability lifecycle end-to-end.

Requirements

  • 4+ years in a security engineering, product security, or DevSecOps role, ideally at a fintech, payments company, or other regulated environment
  • Experience with vulnerability management at scale: CVE triage, SCA tooling, dependency upgrade automation
  • Comfort working with AI-native tooling (Claude Code, Claude Security, or similar) as a daily driver - or genuine excitement to start

Compensation

  • Since our seed round in 2024, we've achieved 23x revenue growth and scaled to multi-billion-dollar annual transaction volume.

Benefits

  • Use Claude Security and Claude Code to scale your coverage - automate reconnaissance, fuzzing, code review, and exploit development.
